There is a sound that anyone who has spent time on a video call in the last five years knows well. It is the sound of a colleague’s voice cutting in and out against a backdrop of traffic, construction, or the ambient hum of an open-plan office.
It is the sound of someone apologising for the wind, or asking – again – to be repeated. Background noise is one of the most common friction points in modern working life, and its impact on productivity, concentration, and call clarity is felt every day across hybrid and office environments alike.
The BH78 is Yealink’s answer to that problem. “If we find the user’s pain point, we need to solve these problems,” says Alex Lin, Headset Product Marketing Manager at Yealink.
“Maybe combining hardware and software together to make a whole solution.”
The headset market has long been driven by specifications – driver size, frequency response, battery life – but the real challenge in enterprise audio is environmental. It is not about what a device can do in a controlled setting. It is about what it can do when someone is walking through a factory floor, sitting in a glass-walled office, or taking a call from a kitchen table. That is the challenge that shaped the development of the BH78.
From Hybrid ANC to Adaptive Hybrid ANC
Active noise cancellation has been part of the headset market for some time. Hybrid ANC – which combines feed-forward and feedback microphones to reduce noise across a wide range of frequencies – marked a meaningful step forward, offering more effective cancellation than earlier single-microphone approaches.
The BH78 goes further with Adaptive Hybrid ANC. Rather than applying a fixed level of noise cancellation, Adaptive Hybrid ANC intelligently adjusts to the user’s environment in real time – dynamically modulating the degree of cancellation depending on what surrounds them. Whether a user moves from a quiet home office to a busy open-plan floor or steps outside into wind and traffic, the BH78 continuously recalibrates to deliver a focused calling and listening experience. The result is noise cancellation that works with the user’s environment rather than against it.
Microphone Noise Cancellation
Alongside its ANC capabilities, the BH78 features a 4-microphone AI noise cancellation system that addresses the other side of the audio equation – not just what the wearer hears, but how clearly they are heard.
The 4-microphone array works in conjunction with Yealink’s AI-powered Noise Cancelling Technology and Acoustic Shield 3.0 to isolate the speaker’s voice and intelligently filter out background noise. The person on the other end of the call hears only the speaker – clearly and without distraction – regardless of what is happening in the surrounding environment. For contact centre agents, remote workers, and anyone whose role depends on being understood as much as on understanding others, this is a meaningful capability.
The Link Between Audio and Outcomes
The conversation around enterprise audio has historically been framed around quality – does it sound good? But the more useful frame is outcomes – what does poor audio cost, and what does good audio enable?
Listener fatigue is well-documented in occupational health research. Cognitive load increases when audio quality degrades, as the brain compensates for missing or distorted information. In environments where communication is core to the work – contact centres, sales teams, remote support functions – the cumulative impact of poor audio on performance and wellbeing is significant. It is also largely invisible, absorbed into broader metrics around productivity or employee satisfaction without ever being attributed to its source.
The BH78 sits within Yealink’s broader BH series, which spans a range of use cases from general office to on-the-go environments. Its position in the portfolio reflects a deliberate approach to segmentation: different environments have different demands, and the right device is the one matched to the actual conditions of use, not the lowest common denominator. For organisations building out their audio infrastructure, the BH series offers a pathway – a coherent set of devices designed around a consistent philosophy, rather than a collection of products competing on spec sheets.
“Before, people would go to the office and work all day,” Alex observes. “Now they may be half the week in the office, half the week at home. They need audio solutions for both scenarios.”
Designed for Comfort
Audio performance means little if a headset cannot be worn comfortably for extended periods. The BH78 underwent multiple rounds of UX testing and refinement throughout its development, with each iteration focused on optimising the overall wearing experience. Fit, clamping force, and weight distribution were all adjusted across testing cycles to ensure that the headset remains comfortable during long shifts – whether in a contact centre, an office, or on the go.
Built for the BH Series, Designed for Hybrid Work
For hybrid workers specifically, the BH78 is designed to move with them. When the microphone boom arm is flipped up, the headset transforms into a sleek, minimalist form – suitable for music, entertainment, and everyday use beyond the desk. It no longer looks or feels like a work device, which matters for users who move between professional and personal contexts throughout the day.
The foldable design reinforces that portability. The BH78 folds in two seconds, making it easy to pack away and carry between the office, home, or wherever work takes the user next. It is a small detail, but one that reflects the broader design philosophy behind the BH78: a headset that adapts to how people work now, not how they used to.
