Comfortable and ergonomic design

The EPOS Adapt 660 headsets are of high quality, elegant design, but above all comfortable to wear all day, even in the office. With its lightweight of 227 grams, it is stable and well distributed over several contact points to ensure a good fit. The carrying system with adjustable headband allows it to be adapted to the morphology of each user and the rotating system allows it to be worn according to your preference, with all the usual comfort.

Black in color, the ADAPT 660 feature a matte finish with leatherette accents on the headband and the circumaural (over-the-ear) ear cups. Touch-sensitive controls are located on the outer panels of the cups, although you can not notice them, as the panels are blank.

Professional and dynamic sound quality

The Active Noise Cancellation Hybrid design allows you to maintain full awareness of your environment when needed. The ear cushions also provide passive isolation against unwanted background noise for perfect listening quality on calls or with your music.

The EPOS Adapt 660 guarantees you a perfect audio experience because of three-voice pick-up microphones integrated into the headset. These microphones are also equipped with a noise cancellation system for use in the noisiest environments.

Powered by EPOS AI, the headphones are adaptive to speech and they study the surrounding environment through machine learning.

Essential and versatile functions

Thanks to its multi-connectivity, you can use it with a wide range of supports, via the multipoint Bluetooth connectivity (up to 8 registered devices and 2 when used simultaneously), the USB dongle or the wired audio cable. The EPOS Adapt 660 headset allows you to connect to all your environments!

You can also accept or reject calls by holding your finger down for a second and tapping twice to place them on hold.

In a call, the microphone is muted or unmuted by moving forward or backward. By double-tapping the headphones, you can disable ANC and muffle the music, and put them into Transparent Hearing mode, during which the ambient mics pick up your voice and your surroundings so that you can talk with ease.

Compatible with all softphones

Thanks to the UC function, it can be easily used with all softphones on the market and features plug & play installation for Microsoft Teams. This feature is astonishingly helpful for those users who rely heavily on Microsoft Teams in their work. Now I can quickly connect to Teams with just a button press.

The EPOS ADAPT 660 have a unique feature set including an exclusive button that launches Microsoft Teams. Powered by EPOS AI, the headphones can adapt to speech and they study the surrounding environment through machine learning.

With Voice assistant

You also have a voice assistant built into your headset, optimized for "Alexa". Simplified management in one word.
