New ABYSS DIANA MR headphones are designed to connect audiophile and head-fi aficionados with professional audio mixing and mastering engineers. The team at ABYSS developed this highly universal full-range planar headphone with ultra-low distortion, near flat frequency response, and smooth addictive clarity to sound.

DIANA® MR maximises listening enjoyment with any level of electronics, from a simple USB dongle through high-end tube and solid-state headphone amplifiers, this headphone has a universal sound character that sounds amazing with them all.

Its low impedance works well with portable battery-operated gear and desktop electronics, extracting amazing resolution out of low voltage power sources while still sounding lush in the bass. This patented newly designed MR planar driver exhibits a flat frequency and phase response with a full natural sound through the bass and midrange, excellent vocals, and an extended high-frequency range that's smooth, clear, and true to the source yet never harsh or brash.

With MR you'll hear crazy low-level details into the recordings without fatigue, glare, or sibilance. We've instilled the best attributes of high-performance headphones into this one model. The sound is just to die for, effortless and easy. This latest ABYSS Diana MR headphone will fit your head, ears, and brain like it was custom-made just for you!
