The Audio-Technica ATH-M20X is a pair of studio headphones which place the emphasis on the lower tones, producing a powerful bass sound. Thanks to the flat, over-ear ear cups, the headphones don't leak any sound and ambient noise is blocked out. The ear cups can be rotated 15 degrees for a comfortable fit. One ear cup can be rotated, making these headphones suitable for DJs too. You can hear how the crowd responds to your music while listening to the track you want to play next, at the same time. The M20X has an included 6.3-millimeter adapter so you can connect the headphones to all kinds of audio equipment.
