The ATH-R70x is Audio-Technica’s first pair of professional open-back reference headphones. Together with the ATH-M70x, they stand as a flagship model in A-T’s professional headphone lineup.
Featuring specially designed drivers and acoustically transparent housings fashioned from aluminum honeycomb mesh, these headphones provide an accurate and natural open-back sound. They also incorporate a new, improved design of our popular 3D wing support system to provide even greater comfort during the prolonged use often required in professional settings. Robust yet lightweight, and equipped with a unique, dual-sided detachable cable that automatically maintains proper stereo orientation (no matter how it’s attached), the R70x headphones are built for lasting comfort, convenience and audio purity."The R70X have a character that might be described as ‘scooped’, but it’s obviously different from that of the M–series ‘phones. There’s still a definite high–frequency lift, but on most material it manifests itself much more subtly as a soft, airy, understated presence rather than a brash treble boost. The bass is excellent: deep, clear and even, and slightly forward without ever sounding unbalanced or overpowering. The mid–range, meanwhile, seems pure and uncoloured, albeit slightly recessed and soft...
Quite a few other high–end open–backed ‘phones have similar just–on–the–scooped–side–of–neutral frequency responses: if not quite a smile curve, then a definite glint–in–the–eye curve. I tend to associate this sort of sound with AKG’s open–back models, for example, and like the K712s and their siblings, the R70xs also present an expansive stereo panorama which occasionally seemed to me to make centre–panned sources appear a little low in the mix. In both cases, though, any deviations from neutrality are small enough that your ears quickly compensate. All in all, these are fine mixing headphones which must be auditioned if you’re in the market for a serious pair of open–backed cans."
