The ATH-M20x professional monitor headphones have long provided a great introduction to our critically acclaimed M-Series. Now you can take that classic M20x studio sound with you wherever you go! Featuring powerful 40 mm drivers, the ATH-M20xBT wireless over-ear headphones deliver the same sonic signature as the wired model, with full-range, high-fidelity audio and enhanced bass. But they also give you the convenience of a Bluetooth wireless connection and have multipoint pairing capability that lets you connect wirelessly to two devices at once. Plus, there’s a low latency mode that improves the synchronicity between audio and video for smooth streaming and gaming. The M20xBT headphones provide up to 60 hours of continuous use on a full charge and up to 3 hours of use on a 10-minute rapid charge (via USB-C connection). The headphones are easy to operate with a microphone and buttons built into the left earcup for convenient handling of calls, music playback, and volume control. We’ve also included a 1.2 m (3.9") cable so you can use M20xBT like a standard pair of wired headphones, when desired.

I purchased these to replace mine 30 year old Sony digital headphones which have now develop chain buzzing in one of the headsets. These particular were highly recommended on the musician forums I belong to. Well, they have a very rich and full sound. They deliver a very flat response with tight bass and clear highs. They fit tighter than my old sonys but than again these are new and my old sonys have been well used. If you have a large head, your ears might get fatigued after long usage. I like a tighter headphone that will not slide off my head while playing my guitars so they work for me. Having 2 included chords with sufficient length that twist and lock into the phones prevents them from pulling out accidentally. I really like these headphones and the price isn’t out of reach for most folks.

I use these with my digital piano. Excellent sound quality, blocking out all outside noise. Very comfortable, and I really like the long, curly cord.
