EPOS Adapt 660 Review: A Work Headset That Actually Sounds Great

The Bluetooth connectivity across multiple devices is the smoothest I've tested. And the entire setup experience, from unboxing to first call, feels like a product that was designed by people who actually use headsets for a living.

The ANC is solid but not class-leading, and the microphone is very good without being outstanding. At $319 MSRP, these sit in premium territory where expectations are high. But for a headset that handles Teams meetings, Zoom calls, Spotify playlists, and airplane noise all from the same pair of ear cups, the Adapt 660 makes a compelling case for being the only headphones on your desk.

Who It's For

Remote workers, hybrid professionals, frequent travelers, and anyone who spends most of their day switching between calls, meetings, and music. If you're tired of using consumer headphones that fumble on work calls, or work headsets that sound lifeless when you play music, the Adapt 660 bridges that gap. The long battery life and lightweight comfort make it especially suited for people who wear headphones 6 to 8 hours a day without wanting to take them off.

If best-in-class ANC is your top priority and you don't need UC certifications, the Sony WH-1000XM6 or Bose 700 will outperform the Adapt 660 in pure noise cancellation. If you need a boom microphone for crystal-clear call quality in loud environments, a dedicated UC headset like the Jabra Evolve2 85 might serve you better. And if $319 is above your budget, the EPOS Adapt E1 earbuds offer excellent connectivity and sound at a lower price point.

Design, Build, and Comfort

The Adapt 660 has a clean, understated design that says "professional" without screaming "gaming headset." The matte black finish is minimal, the branding is subtle, and the overall silhouette is slim enough that you won't look out of place wearing these in a meeting room, at a coffee shop, or on a flight. The build is a mix of metal and high-quality plastic that feels sturdy without adding unnecessary weight.

At just 8 ounces, these are some of the lightest ANC over-ear headphones I've worn. The leatherette and memory foam ear pads are soft, shaped to match the contour of your ear, and the padding across the headband distributes pressure evenly. I wore these for full 8-hour work days without any discomfort, pressure on my jaw, or hot ears. That's not something I can say about every over-ear headset, and for a product designed for all-day professional use, it's a critical detail that EPOS nailed.

The ear cups fold flat and the headband folds inward, making the whole headset compact enough for the included carry case. The swivel mechanism that powers the headset on and off is clever. Rotate the ear cups outward to their listening position and the headset powers on. Fold them flat and it powers off. It feels premium and eliminates the need for a separate power button. The one downside is that resting the headset around your neck can sometimes trigger the off position, requiring a quick reconnect. Once you're aware of it, it's easy to avoid.

Sound Quality

This is where the EPOS and Sennheiser heritage really shines. The Adapt 660 USB-C sounds fantastic for a wireless work headset. The drivers support a frequency range of 17 Hz to 23,000 Hz, and the result is a wide, open soundstage with punchy bass, clear mids, and detailed highs. Music sounds immersive and dynamic. Vocals come through with clarity and presence. Bass has real depth without overpowering everything else. There's a spacious quality to the audio that many noise-canceling headphones lack because they tend to sound boxed in.

The EPOS Connect app lets you customize the sound with several presets including Club, Movie, Speech, Neutral, and a custom Director mode where you can adjust the profile to your taste. The Speech preset strips out bass and focuses on the vocal range, which is perfect for long meeting days. Club gives you more energy for music. I spent most of my time on a custom profile that boosted treble slightly for more detail, and the headset responded well to the adjustment.

For calls, the audio coming from the other end is crisp and natural. The Call Enhancement feature in the EPOS Connect app is worth enabling immediately. It makes voices on calls sound remarkably clear, almost like the person is sitting across from you. Combined with the sidetone feature that lets you hear your own voice at a comfortable level, the call experience is genuinely excellent.

Connectivity and the USB-C Dongle

Connectivity is where the Adapt 660 excels beyond what most consumer headphones offer. The included USB-C dongle plugs into your laptop or desktop and provides a dedicated wireless connection that's more stable and lower-latency than standard Bluetooth. For video calls, this translates to consistent audio sync, no random drops, and no frustrating re-pairing after your laptop wakes from sleep.

Dual-device multipoint Bluetooth lets you stay connected to your phone and laptop simultaneously. When a call comes in on your phone while you're on your laptop, the headset switches automatically. When you end the call, it switches back. I tested this across Teams meetings, Zoom calls, Spotify streaming, and phone calls throughout the day, and the transitions were seamless every time. No drops, no delays, no manual reconnecting. The Bluetooth range held strong at distances well beyond my desk, letting me walk to the kitchen or another room without losing connection.

The dedicated Microsoft Teams button launches Teams with a single press when connected via the dongle. If you live in Teams, this is a nice shortcut. The headset is also certified for Zoom, Google Meet, Cisco Webex, and Amazon Chime, so regardless of your UC platform, you're covered.

Active Noise Cancellation

The adaptive hybrid ANC uses four microphones to monitor your environment and adjust noise reduction in real time. In practice, it does a solid job with consistent background noise like office chatter, HVAC systems, airplane cabin drone, and traffic. The adaptive mode is the standout setting. Rather than applying maximum noise cancellation at all times, it reads the environment and scales the ANC accordingly, which feels more natural and less fatiguing over long sessions.

EPOS has tuned the ANC to let through certain important sounds like voice and announcements, which makes sense for a work headset where you might need to hear a colleague or a train announcement. It's a deliberate design choice, not a limitation. For pure noise isolation while commuting or in a loud open office, it works well enough. But if you're comparing directly to the Sony WH-1000XM6 or Bose 700 in terms of raw noise-blocking power, the Adapt 660 comes up a step short. It's good ANC. It's not the best ANC. For the work-focused use case, the adaptive tuning matters more than maximum silence, and EPOS made the right call.

The three-position switch on the right ear cup lets you toggle between ANC on, adaptive, and off without reaching for an app. Simple, fast, and I used it constantly throughout the day.

Microphone Performance

The three-microphone array with EPOS AI machine learning does a very good job on calls. In quiet to moderately noisy environments, colleagues consistently reported clear, natural audio from my end. The EPOS AI is designed to optimize voice pickup by learning your speech patterns and suppressing background noise in real time, and the results are noticeable. Office noise, keyboard clicks, and general room ambiance are filtered effectively.

In windier or noisier outdoor environments, the mic performance holds up reasonably well but starts to compress the audio slightly. It's not bad. People could still understand me clearly. But compared to headsets with dedicated boom microphones, there's a small but noticeable quality gap. For a boom-less design at this price, the microphone is competitive. It just doesn't reach the same level of clarity that you'd get from something with a physical arm positioned next to your mouth. For 90% of work calls and meetings, the mic quality is more than sufficient.

Battery Life

Battery life is a genuine strength. EPOS rates the Adapt 660 at 30 hours of listening time and 25 hours of talk time on a single charge. In my testing, those numbers hold up. I charged the headset on Sunday night and didn't need to charge again until late Thursday, with 6 to 8 hours of daily use including a mix of calls, music, and ANC. That's exceptional for a wireless headset and means you can genuinely go a full work week without thinking about charging.

The standby time is rated at 360 hours, which means you won't come back to a dead headset on Monday morning even if you forgot to charge over the weekend. Charging takes about 3 hours from empty to full via USB-C, and fast charging is supported if you need a quick top-up. The five-dot LED battery indicator on the headset makes it easy to check your remaining power at a glance.

The EPOS Connect App

The EPOS Connect app is available on desktop and mobile, and it's one of the better companion apps I've used with a headset. The interface is clean and purposeful, with no unnecessary clutter. You can customize EQ presets, adjust sidetone levels, toggle ANC settings, check battery status, manage paired devices, and update firmware all from one place.

The EQ presets are well-tuned. Speech mode is excellent for call-heavy days. Club mode adds energy for music. The custom Director mode lets you dial in your own preferences. Firmware updates push through the app smoothly, and EPOS has been actively updating the Adapt 660 line to improve performance and add features over time. The app isn't flashy, but it's stable, responsive, and does exactly what a professional headset companion app should do.
