Yealink BH78 USB-C/A Bluetooth ANC Headset

The Yealink BH78 USB-C/A Bluetooth ANC Headset is a premium wireless business headset designed for professionals working across offices, home workspaces and on the move. Combining Bluetooth 5.3, Adaptive Hybrid Active Noise Cancellation and AI-powered microphone noise cancellation, the BH78 helps users stay focused while ensuring their voice remains clear during important conversations.

A sophisticated multi-microphone system works alongside Yealink Acoustic Shield technology to distinguish the user's voice from surrounding sounds and suppress distracting background noise. Adaptive Hybrid ANC further enhances concentration by intelligently responding to the surrounding environment, helping create a quieter listening experience for both calls and music.

Designed for comfortable extended use, the BH78 combines an over-ear wearing style, soft ear cushions, hidden microphone boom and foldable construction. Up to 38 hours talk time, up to 120 hours music playback and the included BHC78 wireless charging stand make it a versatile solution for demanding professional and hybrid working environments.

Adaptive Hybrid ANC – Stay Focused Anywhere

The BH78 features Adaptive Hybrid Active Noise Cancellation (ANC), intelligently responding to the surrounding environment to help minimise unwanted distractions.

Whether working in a busy office, travelling or taking calls remotely, the technology helps create a more focused listening environment. Yealink states that Adaptive Hybrid ANC can provide up to 35dB of noise reduction across low, mid and high frequencies.

AI-Powered 4-Mic Noise Cancellation – Be Heard Clearly

Clear communication is supported by an advanced 4-microphone system, combined with AI-powered uplink noise cancellation and Yealink Acoustic Shield technology.

The intelligent processing helps distinguish your voice from surrounding environmental noise, suppressing distractions such as keyboard sounds, background conversations and wind noise. This helps ensure your voice remains clear and professional during calls, whether you're working in a busy office, from home or on the move.

Bluetooth 5.3 Multi-Device Connectivity

With Bluetooth 5.3 and up to 50 metres / 160 feet wireless range, the BH78 provides the freedom to move around the workplace without remaining tied to a computer or mobile device.

The headset supports two simultaneous Bluetooth connections and pairing with up to eight devices, making it particularly convenient for professionals working across multiple communication devices.

The product also includes the BT51C Bluetooth dongle and USB-C/A adapter for convenient PC connectivity.

Designed for All-Day Comfort

The BH78 combines an ergonomic over-ear design with soft, skin-friendly ear cushions to provide a comfortable and secure fit throughout extended meetings and working sessions.

Yealink's CloudSoft Comfort technology, pressure-relieving adjustable headband and cushioned earcups are designed to distribute pressure comfortably, while the foldable design makes the headset easier to transport between different working locations.

Hidden Microphone Boom & Smart Controls

A discreet hidden microphone boom retracts neatly into the headset when it isn't required, giving the BH78 a streamlined appearance for music, travelling and everyday use.

For convenient call control, users can raise the microphone boom to mute and lower it again to unmute. Integrated wearing detection, call controls and dual-sided busylights add further convenience throughout the working day.

Designed for Hybrid Working Wherever the Day Takes You

From focused office work, business trips, to taking calls whilst on the move, the Yealink BH78 is designed to support modern professionals across a variety of working environments. Its wireless connectivity, Adaptive Hybrid ANC, advanced noise cancellation and comfortable over-ear design help provide a consistent calling and listening experience whether you're in the office, travelling by plane or working on the go.

Extended Battery Life & Wireless Charging

The BH78 provides up to 38 hours talk time and up to 120 hours music playback, helping users stay wireless throughout demanding working schedules.

The included BHC78 Wireless Charging Stand provides convenient desktop storage and charging, helping ensure the headset is ready when the next call begins.

Rich Audio for Calls & Music

A 35mm speaker and dynamic EQ help provide detailed audio across both professional conversations and music playback.

The BH78 intelligently optimises audio performance for different listening situations, delivering clear speech for calls alongside rich, natural sound for music and multimedia.
