The open-plan professional needs a headset that fits two contradictory demands at once. Sound professional on every call - even in a noisy office, even working from home, even on a busy floor. And stay aware of the room - one ear on the call, one ear on the colleague approaching, the supervisor's instruction, the customer at the desk.
The Yealink BH70 Mono was engineered for exactly this professional.
This is a wireless Bluetooth single-ear headset built with one clear purpose: to make every call sound professional and to keep one ear permanently open to the world around you. At just 91 grams - lighter than most smartphones - the BH70 Mono achieves its purpose without adding weight, bulk, or complexity to the working day.
The microphone system is where the BH70 Mono makes its most significant statement. Three MEMS microphones in a beamforming array are mounted on a boom arm that is 135.7 mm long - 74% longer than the industry-standard 78 mm boom found on most competing wireless headsets. This longer arm is not a design detail. It is a fundamental acoustic advantage: a microphone positioned closer to your mouth captures your voice with a stronger, more direct signal relative to ambient background noise. Before the beamforming algorithm and Acoustic Shield noise cancellation processing even engage, the BH70 Mono starts from a stronger acoustic position than a headset with a short boom can achieve.
Multiple noise cancellation algorithms work on the combined signal from all three microphones - beamforming focuses the microphone sensitivity precisely on your voice while the algorithms identify and remove background sounds from every direction. Office conversation, keyboard typing, air conditioning, household noise, and outdoor sounds are eliminated before your voice is transmitted. Your callers hear you clearly. Whatever your environment.
The 35mm speaker driver delivers a single-ear audio experience far beyond what mono headset speakers typically offer - dynamic EQ automatically switches between call mode for crisp, clear voice audio, and music mode for richer, fuller sound between sessions. At 50 metres of Bluetooth 5.2 range, movement within any standard office or home environment is unrestricted.
Up to 35 hours of talk time on a full charge with busylight off. 43 hours of music playback. 22 days of standby. A full charge takes just 90 minutes. Multipoint connectivity maintains simultaneous connections to two devices - typically a laptop via the included BT51 USB-C dongle and a smartphone via native Bluetooth.
The integrated busylight on the headset illuminates red when you are on a call, signalling do-not-disturb status to colleagues and visitors in any shared workspace - at home or in the office.
Built and tested to withstand drops and heavy pressure. Compatible with all major collaboration platforms and operating systems out of the box. A charging stand is available separately for those who prefer a permanent charging home for the headset on their desk.
91 grams. One ear free. 35 hours. Three microphones. Every call, crystal clear.
KEY FEATURES
3-Mic Beamforming Noise Cancellation - Multiple Algorithms Working TogetherThe BH70 Mono's three-microphone MEMS beamforming system combines physical beamforming directivity - focusing microphone sensitivity toward your voice - with multiple noise cancellation algorithms trained across diverse real-world acoustic scenarios. Office noise, home noise, and on-the-go noise environments are all addressed. The algorithms identify and separate your voice signal from background sounds arriving from other directions, delivering clean voice transmission regardless of your environment. This multi-layer approach is more effective in variable, complex noise environments than a single-algorithm single-microphone system.
135.7mm Boom Arm - 74% Longer Than Industry StandardMost wireless headset boom arms are approximately 78 mm long - a length that balances aesthetic compactness with reasonable microphone proximity. The BH70 Mono's boom arm is 135.7 mm - 74% longer - positioning the microphone significantly closer to your mouth. This physical proximity advantage means the microphone captures your voice with a stronger, more direct signal relative to ambient background sounds before any processing begins. The longer arm is the primary reason the BH70 Mono's noise cancellation performs above what its entry-level positioning might suggest. The boom arm is fully adjustable and holds its position precisely once set.
91 Grams - Featherlight All-Day Mono ComfortAt 91 grams, the BH70 Mono is exceptionally light for a professional wireless Bluetooth headset with three microphones, a busylight, and a 35-hour battery. The low weight is the result of new premium materials used in the headset frame and headband - engineered to feel lightweight while maintaining the structural durability to pass drop and pressure quality testing. The headband design accommodates a wide range of head shapes, distributing the minimal 91-gram load without concentrated pressure at any point. Soft leatherette ear cushion provides a comfortable contact surface for extended single-ear wearing.
35-Hour Talk Time - The Full Working Week and Beyond Up to 35 hours of continuous talk time with busylight off on a full charge - covering an entire working week of eight-hour call days with hours to spare. 43 hours of music playback. 22 days of standby. A full charge takes just 90 minutes via the included USB-C charging cable. For hybrid professionals who use the headset across long working days and forget to charge overnight, 35 hours provides meaningful buffer against power anxiety.
35mm Speaker with Dynamic EQ - Great Audio for Calls and MusicA single 35mm speaker driver in the mono earcup delivers audio quality above what most mono headsets achieve. Dynamic EQ automatically switches the audio profile between call mode - optimised for voice clarity and speech intelligibility - and music mode - adapted to deliver rich bass, detailed midrange, and crisp highs for genuinely enjoyable audio between calls. The transition is seamless and automatic. You always hear the right audio for what you are listening to.
Bluetooth 5.2 - 50-Metre Range, 2-Device MultipointBluetooth 5.2 provides a stable, efficient wireless connection with a range of up to 50 metres - genuine freedom of movement throughout any home or office environment. Multipoint connectivity maintains simultaneous connections to two devices - laptop via the included BT51 USB-C dongle and smartphone via native Bluetooth. The headset stores up to eight paired devices for instant reconnection.
BT51 USB-C Dongle Included - Stable, Optimised PC ConnectionThe included BT51 USB-C Bluetooth dongle provides a dedicated, optimised connection to your laptop or PC - more stable and consistent than relying on built-in laptop Bluetooth in environments with wireless interference. A USB-A adapter is included for use with standard USB-A ports.
Integrated Busylight - Visual Do-Not-Disturb SignalThe busylight integrated into the BH70 Mono headset illuminates red automatically when you are on a call, providing a clear visual do-not-disturb signal to colleagues and household members in any shared workspace. No separate busylight device required.
Situational Awareness - One Ear Always OpenThe single-ear mono design leaves one ear completely open to the surrounding environment. This is the deliberate, correct choice for professionals who need to remain aware of their surroundings during calls - contact centre agents hearing supervisors, open-plan office workers hearing colleagues, customer-facing professionals hearing visitors, and any professional whose environment requires simultaneous awareness of both the call and the room.
Drop and Pressure Tested - Built for Daily Professional UseThe BH70 Mono has been subjected to high-level quality tests including drop testing and heavy pressure testing, validating its durability under the demands of daily professional use. New premium materials provide structural integrity without adding weight.
Works with All Major PlatformsCompatible with all major collaboration and communication platforms out of the box - including Zoom, Google Meet, Cisco Webex, Cisco Jabber, RingCentral, and 100+ UC platforms and operating systems. One headset covers every platform your organisation and your clients use.

FREQUENTLY ASKED QUESTIONS
Q: Why choose a mono wireless headset over a stereo wireless headset?
A: A mono single-ear headset leaves one ear completely open to your physical environment during calls. For contact centre agents who need to hear supervisors providing live coaching, open-plan office workers who need to remain accessible to approaching colleagues, reception and customer-facing staff who need to hear walk-in visitors, and any professional whose environment requires simultaneous awareness of the room and the call - a mono design is the right tool. A stereo headset that seals both ears is the correct choice for professionals who need full audio immersion and maximum passive isolation. The BH70 Mono and BH70 Dual are available to cover both preferences; this listing is the Mono only.
Q: What does the 135.7mm boom arm mean in practice?
A: Most wireless headset boom arms are approximately 78 mm long - a compact length designed for aesthetic tidiness. At 135.7 mm, the BH70 Mono's boom arm is 74% longer, physically positioning the microphone significantly closer to your mouth. A microphone closer to its target captures a stronger, more direct voice signal relative to background noise. This physical proximity advantage is the most important factor in microphone noise cancellation performance - it is why the BH70 Mono's three-microphone beamforming system outperforms many competing headsets with shorter booms, regardless of the number of microphones they use.
Q: Is a charging stand included?
A: No. This listing is the headset without a charging stand. A Yealink charging stand compatible with the BH70 is available separately. The headset charges via the included USB-C cable connected to any USB power source or laptop port.
Q: How does multipoint connectivity work?
A: Multipoint allows the BH70 Mono to maintain simultaneous Bluetooth connections to two devices - typically your laptop via the BT51 USB-C dongle and your smartphone via native Bluetooth. Both connections are live at the same time. When a call arrives on your phone while your laptop is connected, you hear it through the headset. Switching between devices is handled by the headset automatically when a call begins on either device. Up to eight devices can be stored in the pairing list for instant reconnection.
Q: What is the BT51 USB-C dongle and why is it included?
A: The BT51 is Yealink's dedicated Bluetooth USB dongle - it plugs into your laptop's USB-C port and provides a dedicated, optimised Bluetooth connection to the BH70 Mono. Built-in laptop Bluetooth varies in quality between models and can suffer from interference in crowded wireless environments. The BT51 provides a more consistent, stable connection for professional headset use. A USB-A adapter is included for compatibility with USB-A ports.
Q: How long does the battery last in real-world use?
A: The 35-hour talk time figure is measured with the busylight off. In real-world use with the busylight active during calls, expect slightly lower talk time - still well above the daily requirements of most professionals. Music playback extends to 43 hours. Standby reaches 22 days. Most professionals who charge the headset overnight will never experience a mid-day low battery situation.
Q: Is the BH70 Mono suitable for contact centre use?
A: Yes. The three-microphone beamforming system with Yealink Acoustic Shield noise cancellation handles high-density, noisy floor environments effectively. The 135.7mm boom arm positions the microphone for optimal voice capture at desk-use distances. The single-ear design keeps one ear open to team leaders and supervisors. The 35-hour battery life covers full shifts and beyond. The busylight signals availability. And the headset has been drop-tested and pressure-tested for daily professional durability.
Q: What warranty does the Yealink BH70 come with?
A: The Yealink BH70 is covered by a 2-year manufacturer warranty. Please confirm current terms with your retailer at time of purchase.
