Audio Technica ATH-R70x are an extremely light weight open headphone with a new, sleek design and a detailed, neutral, open sound. The treble response is a little softer than with other, sometimes bright, open Audio Technica models, making the ATH-R70x easy to listen to for long periods and easier to listen to with pop, brighter recordings or lower quality files.
Very light weight with large ear cups, a replaceable cable and a carry bag. The ATH-R70x is a 470 ohm headphone with high sensitivity, so it is not too hard to power, but is meant to pair with a non-usb powered headphone amp.
From Audio Technica: The ATH-R70x is Audio-Technica’s first pair of open-back reference professional headphones. Featuring specially designed drivers and acoustically transparent housings fashioned from aluminum honeycomb mesh, these headphones provide an accurate and natural open-back sound.
