Hands-on Review: EPOS Adapt 660 perfect choice for modern professionals
Review: Why settle for a flashy, uncomfortable ride when you could glide through your day in calm, effortless style?
That's the experience the EPOS Adapt 660 USB-C offers - a sleek, purpose-built wireless headset that combines exceptional comfort, intelligent noise cancellation, and finely tuned audio.
Designed for modern professionals but ideal for anyone craving quality sound and focus, this headset is a quietly powerful contender.
Built on EPOS' proprietary BrainAdapt technology and featuring refined audio heritage from its former partnership with Sennheiser, the Adapt 660 is less about style statements and more about performance and long-term usability.
Whether you're jumping between Teams calls or zoning out to music in a noisy café, these headphones are up to the task.
Subtle design and serious comfort
The Adapt 660 isn't designed only to stand out - but it's also built to blend in.
With understated black earcups, silver accents, and a foldable, travel-ready build, it leans into its 'enterprise headset' label with quiet confidence. But the real story is how it feels: at just over 200 grams, it's one of the lightest ANC headsets in its class, with plush, oval-shaped earpads and a padded headband that make all-day wear genuinely comfortable.
Touch controls on the right earcup are simple and responsive - swipe for volume or tracks, tap to pause.
A three-way switch lets you control the adaptive ANC, and a dedicated button launches Microsoft Teams with a single press.
Dual Bluetooth pairing makes it easy to connect to your phone and laptop at once, a must-have for multitaskers.
Battery life is stellar. In testing, the Adapt 660 lasted around 30 hours on a single charge, making charging a rare chore - even for heavy users.
Smarter noise cancellation
EPOS' hybrid adaptive ANC system is among the smartest on the market.
Rather than trying to block out everything, it focuses on reducing cognitive load - suppressing distracting background noise like HVAC hum or office chatter while still allowing relevant sounds to filter in when needed.
It's an approach that feels more natural and less isolating than many competing ANC systems, which often create a boxed-in or artificial listening experience.
This is particularly helpful for hybrid workers or travellers who need to stay semi-aware of their surroundings.
The headset also includes four beamforming microphones, powered by EPOS AI, which dynamically adjust for optimal speech clarity during phone and video calls. Voices come through clearly, even in less-than-ideal acoustic environments.
Audio performance with a professional edge
Though EPOS now leads the brand, the Adapt 660 still benefits from Sennheiser's renowned audio tuning.
The stereo sound is spacious and precise, with excellent balance across the frequency spectrum.
Bass is present but not overpowering, mids are clean, and highs are detailed without harshness.
Whether I was on a call, streaming music, or watching action films, the headset delivered consistently enjoyable sound.
It also supports custom EQ profiles via the companion app, so you can tailor your sound if desired - but most users will find the default tuning well-rounded and satisfying.
Subdued yet superb
The EPOS Adapt 660 USB-C may not have the flash of some consumer-oriented headphones, but it makes up for it with thoughtful design, real-world usability, and excellent sound.
From its lightweight build and smart ANC to seamless device switching and great call clarity, it's one of the most well-rounded headsets I've tested.
If your day shifts between meetings, playlists, and moments of focus, the Adapt 660 adapts with ease and offers excellent value in a crowded market.
