Fanvil DH401B key verified features

Technical specifications

Who is the Fanvil DH401B for?

The DH401B is especially relevant for users who spend substantial time on voice calls but do not want a closed-ear or in-ear headset. Typical use cases include account managers moving between desks and mobile calls, managers who need to hear colleagues while participating in online meetings, reception-support users who divide attention between callers and walk-in visitors, field supervisors who must remain aware of nearby activity, and hybrid workers who connect to both a laptop and smartphone.

It is not automatically the best choice for every headset requirement. Users who need stronger acoustic isolation in very loud environments may prefer an over-ear or closed design. Likewise, users who require long-range movement far beyond the normal Bluetooth working radius may need a DECT model. The DH401B is strongest when lightweight open wear, awareness, portability and two-device Bluetooth switching matter more than complete acoustic isolation.

Fanvil DH401B Tanzania

Businesses in Tanzania looking for a professional Bluetooth headset often need to balance call clarity, comfort, mobility and compatibility with the communication devices already in use. The Fanvil DH401B is a strong option when staff members work between a laptop and smartphone, need to hear people around them, or spend the day moving through an office rather than staying at one desk. Its open-ear structure is particularly useful where awareness matters: a user can participate in a call while remaining conscious of colleagues, visitors or operational activity. For procurement teams, the important step is to confirm the expected endpoint mix before ordering. A user working mainly with a Windows or macOS computer and mobile phone has a straightforward Bluetooth use case, while customers planning to pair the DH401B to specific Fanvil desk phones should verify compatibility for the exact phone model and firmware. FourTeck can help frame that check before a quotation is finalized.

For Tanzanian organizations standardizing user accessories, consider the work profile rather than issuing the same headset to every employee. Mobile managers, sales staff, service coordinators and hybrid workers may value the 13.6 g open-ear fit and two-device multipoint capability. Contact-center staff seated in consistently noisy spaces may require a different acoustic form factor. Battery planning also matters: the DH401B gives up to 5 hours of talk time from the headset, and the portable case extends total talk time to up to 23 hours when users return the headset to the case between sessions. This makes it well suited to mixed meeting and mobile-call patterns rather than uninterrupted all-day calling without charging breaks.

A business quotation should therefore include expected quantity, devices to be paired, typical daily call duration, workplace noise level and whether the organization is also refreshing IP phones or unified communications. FourTeck Tanzania can place the headset requirement within a broader voice environment through its business IT and communication services, while the Tanzania technology shop provides context for related products. This approach reduces the risk of buying a headset that is technically capable but poorly matched to the user role or endpoint.

Fanvil DH401B OWS Bluetooth Headset Dar es Salaam

Dar es Salaam organizations frequently combine office-based work with mobile customer communication, making two-device Bluetooth connectivity a practical purchasing consideration. The DH401B can remain connected to two devices at the same time, such as a work laptop and mobile phone, allowing staff to move between collaboration calls and cellular conversations without building the day around repeated pairing. This can be helpful for sales teams, project coordinators, administrative users and managers working across meetings, customer calls and messaging platforms. Its open-ear design also suits offices where users still need to hear a colleague speaking nearby or respond to activity at a reception or shared workspace.

For a Dar es Salaam rollout, headset selection should include a compatibility and user-environment check. Bluetooth range is specified at about 10 m under normal conditions, but walls, furniture, radio congestion and endpoint behavior can affect real-world mobility. Procurement teams should not treat that number as a guaranteed room-to-room distance. The headset’s dual microphones, AI environmental noise cancellation and acoustic echo cancellation are designed to improve transmitted voice, but an open-ear product will not isolate the listener in the same way as a sealed headset. Users working beside constant machinery or very loud conversations may need a different design even when the DH401B’s microphone processing helps the far-end listener.

A sensible quotation request for Dar es Salaam should state how many users need headsets, whether they connect to PCs, smartphones or Fanvil phones, the expected applications, and whether charging availability exists at desks. The included charging case is useful for staff who move between meeting rooms, customer sites and office areas, because it allows charging away from a fixed desktop dock. Organizations refreshing telephony at the same time can also review FourTeck Tanzania’s broader IT, telecom and collaboration portfolio so that headset selection, IP phones, network readiness and user workflow are considered together rather than as unrelated purchases.

Fanvil DH401B OWS Bluetooth Headset Mwanza

For businesses in Mwanza, a wireless headset may be part of a broader effort to improve communication between front-office staff, managers, field teams and branch users. The Fanvil DH401B is particularly relevant where personnel need a headset that is easy to carry, quick to pair and comfortable for intermittent calls throughout the day. At 13.6 g, the headset adds very little weight compared with conventional over-ear designs, and its ear-hook format helps keep it positioned without placing the speaker inside the ear canal. This can be attractive to users who dislike in-ear devices or who need to maintain awareness of their immediate environment.

When planning a Mwanza purchase, organizations should focus on work patterns instead of specification lists alone. Up to 5 hours of headset talk time can be sufficient for employees who alternate calls with other tasks and return the unit to its charging case between sessions. Users who remain continuously connected for longer periods should calculate whether charging opportunities fit their workflow. The case extends total available talk time to up to 23 hours and music listening to up to 36 hours, but those figures depend on recharging the headset from the case. The headset also supports up to eight devices in its pairing list, which can simplify reuse across a user’s approved devices, although only two are connected simultaneously.

Compatibility should be recorded before volume ordering. For standard Bluetooth computers and mobile devices the requirement is straightforward, while pairing with Fanvil VoIP phones should be checked against Fanvil’s current compatibility information for the exact phone model. Buyers should also specify whether the headset is for Teams, Zoom, browser calling, softphones or ordinary mobile calls, because user expectations can differ between applications. FourTeck can help organize the procurement conversation around quantity, endpoint mix, user roles and associated telephony requirements, avoiding assumptions about local stock, lead time or phone-model compatibility until they are confirmed during quotation.

Fanvil DH401B OWS Bluetooth Headset Arusha

Arusha businesses in hospitality, travel, professional services, administration and distributed operations may need communication tools that support users who are rarely fixed to one desk. The Fanvil DH401B addresses that profile with a compact open-ear format, Bluetooth 5.4 connectivity and a charging case that can travel with the user. The ability to connect to a PC and smartphone at the same time can reduce friction for employees who use a laptop for meetings but receive customer or operational calls on a mobile device. Instead of keeping separate headsets for each endpoint, the user can work with one paired device set and switch according to the active call.

Open-ear audio is also a meaningful design choice in environments where staff need to stay approachable. A hotel operations coordinator, for example, may need to hear a colleague while on a call; an office manager may need awareness of a shared workspace; a field supervisor may want to avoid complete isolation from the surroundings. The trade-off is that open-ear listening does not block external sound. Procurement teams should therefore distinguish between microphone noise reduction, which helps the remote party hear the user more clearly, and physical noise isolation for the wearer, which is not the purpose of the DH401B. This distinction prevents unrealistic expectations in louder environments.

Before ordering for an Arusha team, identify the primary devices, daily call load, charging routine and workplace noise profile. Confirm Fanvil phone compatibility by model where a desk phone is part of the workflow. Also consider whether users need a right-ear-only design, because Fanvil specifies the wearing orientation as right ear. These practical details matter as much as headline features. A well-prepared request lets FourTeck focus the quotation on the right user group and identify when a different headset category may be more suitable for another department within the same organization.

Fanvil DH401B OWS Bluetooth Headset Dodoma

Organizations in Dodoma evaluating headsets for administrative offices, project teams, service desks or hybrid staff should start with how calls are actually handled. The Fanvil DH401B is designed around mobility and awareness rather than heavy acoustic isolation. Its open-ear speaker sits outside the ear canal, while an ear hook supports the headset during movement. This makes it useful for staff who need to talk while continuing to interact with the physical workspace. The 13.6 g weight is particularly helpful for users who dislike the pressure and heat of larger headsets during repeated meetings.

From a technical perspective, the DH401B uses Bluetooth 5.4 with HFP, A2DP and AVRCP profiles and supports a typical operating range of around 10 m. The headset can remember up to eight paired devices and connect to two simultaneously. For an employee with a work laptop and phone, that simplifies daily setup; for shared desks or hot-desking environments, organizations should still define device ownership and pairing procedures so users do not leave personal devices in the pairing list. The hardware includes mute, multifunction and volume controls, and the charging case provides a practical place to store the headset when it is not in use.

For procurement in Dodoma, ask for a quotation with user count, intended endpoints and expected deployment date, then validate compatibility before committing to a large batch. If the headsets will be paired with Fanvil phones, supply the exact phone model. If they will be used mainly with laptops, list the operating systems and calling applications. If staff spend many hours on continuous calls, compare the 5-hour headset talk-time figure with the team’s schedule. This evidence-based approach helps determine whether DH401B is the right fit, rather than selecting it only because it is wireless or newly released.

Fanvil DH401B OWS Bluetooth Headset UAE

For UAE companies managing office, mobile and hybrid communication, the Fanvil DH401B provides a lightweight headset option for users who regularly switch between a computer and smartphone. Bluetooth 5.4 multipoint allows two simultaneous connections, which is useful for managers, sales personnel, consultants and service teams that move between collaboration software and mobile calls. The open-ear design also supports awareness in shared offices and mobile working situations. Because the speaker does not seal the ear, users can remain conscious of nearby conversation, announcements or movement without repeatedly removing the headset.

The DH401B should be selected according to acoustic conditions. Its dual omnidirectional microphones and AI environmental noise cancellation are designed to improve voice transmission, while acoustic echo cancellation supports cleaner calls. Those technologies do not make an open-ear headset equivalent to a closed noise-isolating model for the wearer. In a relatively controlled office or hybrid-work setting, the design can feel natural and convenient. In very loud operational environments, buyers should test the use case or consider a different headset form factor. This matters for UAE organizations with mixed environments such as corporate offices, showrooms, warehouses and customer service areas.

Regional procurement teams can align headset purchasing with wider communication standards by reviewing FourTeck UAE IT and telecom solutions. A quotation should identify headset quantity, endpoint models, call applications, preferred deployment schedule and any desk-phone integration. Buyers should also account for the right-ear wearing orientation, 10 m stated Bluetooth range and the charging pattern needed for up to 5 hours of talk time from the headset. The portable case extends total talk time to up to 23 hours, making it useful for users who can dock the headset between calls or meetings.

Fanvil DH401B OWS Bluetooth Headset Uganda

Ugandan businesses upgrading voice communications may use the Fanvil DH401B as an accessory for staff who need wireless freedom without the bulk of a conventional office headset. The unit’s open-ear ear-hook design is intended for light wear and environmental awareness, which can work well for branch managers, customer-facing personnel and mobile employees. Bluetooth 5.4 multipoint supports simultaneous connection to two devices, making the headset particularly practical where laptop-based softphone calls and mobile calls are both part of the workday.

A procurement plan should distinguish between Bluetooth compatibility and specific phone compatibility. PCs and smartphones typically connect through standard Bluetooth profiles, while compatibility with individual Fanvil VoIP phone models should be checked before ordering. Fanvil explicitly notes that compatibility varies by VoIP phone model. Organizations standardizing telephony should therefore provide the exact phone model, firmware context where relevant, and expected call platform. The headset can store up to eight paired devices, but only two connections are active at a time, so user training should explain which devices should remain paired and how to manage changes.

For Uganda-based projects, the headset can be considered alongside broader IP PBX and networking requirements. The FourTeck Uganda communication solutions site provides regional context for IP PBX, VoIP and networking. When requesting the DH401B, include quantities, city or site locations, primary endpoints, expected call duration and whether users need a headset for office, field or mixed work. Do not assume that one headset type suits every department; an open-ear model excels in awareness and mobility, while fixed high-volume call roles may require a different battery or acoustic profile.

Fanvil DH401B OWS Bluetooth Headset Kampala

Kampala offices often combine mobile phones, laptops, cloud meetings and IP telephony in the same user workflow. The Fanvil DH401B can simplify that mix for users who mainly need two Bluetooth endpoints. A laptop can remain connected for softphone or video-meeting audio while a smartphone stays available for direct calls. Multipoint does not eliminate the need for clear user procedures, but it reduces the repeated pairing process that can frustrate staff moving between applications. The headset’s controls for volume, mute and multifunction calling functions also keep common actions close to the user.

Comfort is another buying factor. The headset itself weighs 13.6 g and uses an open-ear right-ear design. For users who find in-ear devices uncomfortable, keeping the speaker above the ear canal can feel less intrusive. At the same time, open-ear audio means surrounding sound remains audible, so Kampala organizations should consider where users will sit. A manager in a private or moderately active office may benefit from the balance of awareness and clear calling, while a staff member beside loud equipment may need stronger isolation. AI environmental noise cancellation improves microphone pickup for the remote party but does not physically block noise reaching the wearer.

When preparing a Kampala quotation, list the number of users, their main devices, any Fanvil phone models, and whether calls are mostly short customer interactions or prolonged meetings. Battery fit should be checked against that pattern: up to 5 hours of talk time from the headset can suit intermittent calling, and the case can extend total talk time to up to 23 hours when used for recharging between sessions. A small pilot with representative users can be valuable before a larger rollout because comfort and acoustic preference are personal even when technical compatibility is correct.

Fanvil DH401B OWS Bluetooth Headset Arua

For organizations in Arua, practical wireless communication often depends on equipment that is simple to carry, recharge and use across different devices. The Fanvil DH401B fits that requirement with a compact charging case and Bluetooth connectivity rather than a fixed desktop base. This is helpful for staff who divide time between an office, meetings and mobile work. The open-ear design leaves the ear canal uncovered, which supports situational awareness and can be useful for personnel who must hear coworkers or nearby activity while remaining connected to a call.

The headset’s 10 m stated Bluetooth range is intended for normal short-range device use, not long-distance roaming across a building. For users who must walk much farther from a desk endpoint, a DECT headset may be more appropriate. The DH401B instead emphasizes portability and dual-device Bluetooth. Up to two simultaneous connections allow a phone and computer to remain linked, while the pairing list can hold up to eight devices. This is a useful distinction when comparing products: remembered pairings make device management easier, but they are not the same as eight concurrent connections.

Arua procurement teams should verify user priorities before choosing quantities. If staff make intermittent calls and can return the headset to its case, the up-to-23-hour total talk-time figure can support multiple sessions across the day. If users need continuous calling with no charging opportunity, the 5-hour per-headset talk time must be considered directly. For Fanvil desk-phone users, exact model compatibility should be checked. For laptop and smartphone users, note the applications and operating systems in the quotation request so the intended workflow is clear. This prevents a generic headset purchase from becoming a support problem after deployment.

Fanvil DH401B OWS Bluetooth Headset Mbarara

Businesses in Mbarara that rely on mobile coordination, customer calls and laptop-based meetings can evaluate the Fanvil DH401B as a lightweight professional accessory. Its design differs from conventional call-center headsets because it does not enclose the ear. Instead, an ear hook supports the headset while the speaker sits above the ear canal. This allows users to remain more aware of their environment, making it useful in offices where face-to-face interaction continues while staff are handling calls. The 13.6 g weight also reduces the physical bulk carried by mobile employees.

For technical planning, Bluetooth 5.4 with HFP, A2DP and AVRCP covers the primary voice and media use cases. Two simultaneous device connections can simplify switching between a work PC and smartphone. The DH401B also supports AAC and SBC audio codecs, full-duplex communication, AI environmental noise cancellation and acoustic echo cancellation. These features support everyday professional calls, but endpoint software, radio conditions and application configuration still affect the experience. Organizations should avoid assuming that a headset alone can correct poor network quality or a badly configured softphone environment.

A Mbarara purchase request should state whether the headset is being added to an existing communication system or delivered as part of a new IP telephony project. If users already have Fanvil phones, provide the model numbers so compatibility can be checked. If the organization is introducing softphones, indicate the preferred application and endpoint type. User comfort should also be considered because the DH401B is specified for right-ear wearing. By identifying these details before ordering, procurement teams can separate technical suitability from personal wearing preference and make a more reliable decision for a larger user group.

Fanvil DH401B OWS Bluetooth Headset Gulu

In Gulu, the Fanvil DH401B can suit organizations that need a straightforward wireless calling tool for managers, coordinators, sales staff or hybrid users. The key advantage is not simply that it is Bluetooth; it is the combination of an open-ear design, very low headset weight and multipoint connectivity. Users can keep a computer and smartphone connected at the same time, which can reduce switching friction during a workday that combines application-based meetings, direct mobile calls and other audio tasks.

The portable charging case makes the DH401B more useful for staff who are not permanently seated near a charger. The headset battery is rated at 60 mAh with about a two-hour charge time, up to 5 hours of talk time and up to 8 hours of music playback. The case uses a 400 mAh battery and extends total talk time to up to 23 hours or music time to up to 36 hours. Procurement teams should understand these as usage figures under manufacturer test conditions rather than fixed guarantees for every application and environment. Volume level, connection behavior and use pattern can influence real-world runtime.

For a Gulu deployment, consider whether users need awareness more than isolation. The open-ear design works well when hearing the workplace matters, but it also means background sound remains audible to the wearer. Dual microphones with AI ENC are aimed at improving how the user’s voice reaches the far end. Before ordering, provide FourTeck with the number of headsets, device types, Fanvil phone models where relevant, expected call duration and any requirement to standardize accessories across multiple sites. A clear bill of requirements supports more accurate product selection than a request based only on price.

Fanvil DH401B OWS Bluetooth Headset Kenya

Kenyan businesses searching for the Fanvil DH401B are likely to compare it with conventional Bluetooth office headsets, DECT models and consumer earbuds. The DH401B occupies a distinct middle ground: it is a professional open-ear device with a microphone boom and business-call controls, but it remains highly portable and connects directly through Bluetooth. The 13.6 g headset is designed for right-ear wearing and keeps the ear canal open, which can appeal to users who want less occlusion and greater situational awareness during office or mobile work.

The main buying questions should be tied to user behavior. Does the employee switch frequently between a laptop and smartphone? Multipoint is valuable. Does the employee sit in a relatively controlled environment where hearing colleagues is helpful? Open-ear wear is relevant. Does the person need to roam far from a base station? A Bluetooth range of around 10 m may be limiting compared with DECT. Does the user spend eight uninterrupted hours on calls? The 5-hour headset talk-time figure means charging workflow must be considered. These questions create a more useful comparison than choosing by price alone.

Organizations operating in Kenya can review related regional technology coverage through FourTeck Kenya. For a quotation, include the number of units, exact devices and applications, whether Fanvil desk phones are involved, and the expected deployment environment. If buying for a mixed workforce, consider a small validation batch for representative roles before standardizing at scale. This helps confirm fit, comfort, call behavior and pairing procedures without assuming that every department has the same acoustic or mobility needs.

Fanvil DH401B OWS Bluetooth Headset Kuwait

For Kuwait-based offices and mobile business users, the Fanvil DH401B provides an open-ear alternative to traditional enclosed headsets. The design can suit consultants, sales professionals, project managers and administrative users who need to hear colleagues or surrounding activity while participating in calls. Bluetooth 5.4 connectivity removes the need for a proprietary wireless base in standard PC and smartphone workflows, and multipoint allows two connected devices to remain available for switching during the day.

The acoustic design should be matched carefully to the workspace. Dual omnidirectional microphones, AI environmental noise cancellation and acoustic echo cancellation support clearer transmitted voice, but the open speaker arrangement intentionally does not block external sound. A quiet office, private workspace or moderately active shared area is therefore a more natural fit than an extremely loud industrial location. The headset speaker supports a 20 Hz–20 kHz frequency range, while speech-mode bandwidth is 100 Hz–8 kHz. AAC and SBC codecs support media as well as calling, so the device can serve mixed communication and listening tasks.

Kuwait procurement teams should also consider mobility and battery behavior. The headset has up to 5 hours of talk time per charge, with the charging case extending total talk time to up to 23 hours when the headset is recharged between uses. Users who spend time away from a fixed desk can keep the case with them rather than relying on a desktop dock. Before finalizing an order, provide the exact Fanvil phone models where applicable because compatibility can vary. For PC and mobile use, identify the key calling applications and user role so that the quotation reflects the real workflow rather than only the hardware specification.

Fanvil DH401B OWS Bluetooth Headset Ghana

Ghanaian organizations modernizing hybrid communication can consider the Fanvil DH401B for users who want a light, unobtrusive headset that does not cut them off from the surrounding workspace. The open-ear design can be useful for team leaders, supervisors, customer-facing staff and mobile professionals. Unlike in-ear earbuds, it keeps the ear canal open; unlike a full over-ear headset, it adds very little bulk. This makes the device well suited to users who alternate calls with in-person interaction.

Two-device Bluetooth multipoint is another practical feature for teams that use both computers and smartphones. A user can keep both endpoints connected rather than manually disconnecting and pairing throughout the day. The DH401B can remember up to eight devices, but procurement and IT teams should define which endpoints staff are allowed to pair in managed environments. The 10 m stated Bluetooth range is appropriate for personal-area use around a desk or nearby workspace, but businesses that require wider roaming should compare DECT options rather than expecting Bluetooth to cover an entire floor or building.

For a Ghana quotation, include quantity, workplace type, primary calling device and expected daily call profile. If the headset is to be used with Fanvil VoIP phones, provide exact models so compatibility can be validated. If the organization is refreshing voice infrastructure, the headset can be considered alongside IP phones, PBX, switching and Wi-Fi rather than purchased in isolation. Battery expectations should also be communicated to users: up to 5 hours of talk time comes from the headset itself, while the portable case extends available talk time through recharging. This distinction helps teams plan realistic usage and avoids confusion between continuous and cumulative battery figures.

Fanvil DH401B OWS Bluetooth Headset Nigeria

For Nigerian businesses with mobile managers, distributed teams and mixed PC-and-smartphone workflows, the Fanvil DH401B offers a professional Bluetooth headset focused on flexibility. The headset connects to two devices simultaneously and weighs 13.6 g, making it easy to carry between desks, meeting spaces or customer-facing areas. Its ear-hook open-ear design is aimed at users who need to stay aware of their surroundings, which can be particularly helpful in collaborative offices where people still interact face to face while using voice applications.

Noise management requires realistic expectations. The DH401B uses dual microphones and AI environmental noise cancellation to reduce unwanted sound in the voice pickup path, helping the person on the far end hear the caller more clearly. Acoustic echo cancellation also supports cleaner communication. However, the wearer still hears environmental sound because that is the purpose of the open-ear format. Teams working in very noisy operational spaces should compare alternative headset styles that provide more physical isolation. In quieter office, home-office and mobile-work settings, the DH401B’s awareness can be an advantage rather than a limitation.

A Nigeria procurement request should specify whether the headset will connect to smartphones, PCs or supported Fanvil phones, plus the applications used for calls. Organizations should also consider user schedules against the up-to-5-hour talk time and plan use of the charging case, which extends total talk time to up to 23 hours. The pairing list supports up to eight devices, useful for users who work across more than one computer or phone over time. Before bulk purchase, a representative user trial can confirm comfort, right-ear fit, microphone positioning and application behavior so that a large deployment is based on actual operational use rather than specification alone.

Fanvil DH401B OWS Bluetooth Headset Seychelles

Seychelles businesses in hospitality, professional services, tourism support, administration and multi-site operations may need headsets that are portable enough for users who do not remain at one workstation. The Fanvil DH401B is designed for that type of movement. Its compact charging case, low 13.6 g headset weight and direct Bluetooth connection make it easier to use with mobile devices and laptops than a headset that depends on a fixed wireless base. Open-ear wear also allows staff to remain conscious of guests, colleagues and nearby activity during calls.

For customer-facing roles, this balance can be useful because the user is not acoustically separated from the room. At the same time, organizations should assess whether privacy and concentration requirements favor a more closed design for some roles. The DH401B’s AI environmental noise cancellation is focused on microphone pickup; it helps clean the user’s transmitted voice but does not remove surrounding sound from the wearer’s experience. That distinction is important when specifying headsets for reception, back-office, operations and remote-work users, as each group may need a different acoustic profile.

A Seychelles quotation should therefore describe users rather than only state a quantity. Include the main endpoints, typical call duration, expected environment and any Fanvil phone model that must be supported. The headset can connect to two devices simultaneously and stores up to eight paired devices, which is useful for people who alternate between work systems. Battery planning is also straightforward when users return the headset to its charging case between calls: the headset offers up to 5 hours of talk time per charge, and the case extends cumulative talk time to up to 23 hours. These factors make the DH401B a practical candidate for mobile professional communication when its open-ear design matches the workplace.

Compatibility, setup and buying guidance

Pairing is straightforward: power on the headset, select “LINKVIL DH401B” from the Bluetooth device list and complete pairing. The headset can connect to two devices simultaneously. For organizations using Fanvil VoIP phones, model-specific compatibility should be checked before purchase because Fanvil notes that compatibility varies by phone model. For PC and smartphone deployments, organizations should still validate the intended operating system, softphone or collaboration application during a pilot if the rollout is business critical.

The headset is right-ear only. Users should align the speaker above the ear canal, position the ear hook behind the ear and adjust the microphone boom. The headset powers on when the charging case opens and powers off when returned to the case with the lid closed; manual power control is also available. The package includes the DH401B headset, charging case, USB cable, quick-start guide and safety information.

Fanvil DH401B FAQs

Quotation checklist

For a faster and more accurate DH401B quotation, provide the following information: required quantity, city or delivery destination, primary user role, PC or smartphone operating environment, softphone or meeting application, exact Fanvil phone model if applicable, approximate daily call duration, typical noise level and intended deployment date. If the purchase is part of a wider IP phone or PBX upgrade, include that scope so endpoint compatibility can be considered as one project.

Decision recap

The Fanvil DH401B is best suited to professionals who value a light open-ear headset, awareness of their surroundings, two-device Bluetooth connectivity and a portable charging workflow. Its verified specifications include Bluetooth 5.4, 10 m stated range, two simultaneous connections, dual-microphone AI ENC, a 13.6 g headset weight, up to 5 hours talk time per headset charge and up to 23 hours total talk time with the case.

Choose another form factor if the user needs stronger acoustic isolation or long-range roaming beyond normal Bluetooth use. For Fanvil desk-phone deployments, verify the specific phone model before purchase. FourTeck can help turn those requirements into a clear quotation and compatibility discussion without assuming stock, delivery time, warranty terms or model support until they are confirmed.
