THE ADAPT 660

The soft bundled case has just enough room inside the ADAPT 660 and its cables.

Much like most headsets in its class the ADAPT 660 is primarily made out of plastic, leatherette and aluminum but unlike most it weighs just 227g.

This is clearly a medium sized headset.

Both earcups are also made out of plastic but have an aluminum ring on the outside.

The EPOS Sennheiser logo is placed just over both earcups.

I was a bit surprised to see that the bluetooth on/off switch was located at the front top of the right earcup (almost hidden).

Moving at the rear of the right earcup we find the ANC switch (max/adaptive/off) and the dedicated teams/pairing button while at the base we find the USB-C and 3.5mm ports.

The exterior of the right earcup also acts as a touch pad so you need only swipe up/down to increase/reduce volume, left/right to change tracks and mute/unmute the microphone, single tap to play/pause and accept calls, double tap to turn talkthrough on/off and put calls on hold, 1 second tab to reject/end calls, 2 seconds tap to activate voice assistant/Alexa and 4 seconds tap to check battery life.

All of the voice microphones are also located at the front of the right earcup.

Left and right markings are placed on the fabric in each earpad as seen above.

Leatherette is also used to dress the headpad which is soft and well padded.

People who move a lot will be happy to learn that the earcups fold and rotate to make it easier to store and/or carry (folding the headset turns it off).

The headband can extend on either side up to 37mm (74mm total) via 15 increments (not visible ones).
