Excerpt: Just as I started working on this review, I met with Naotaka Tsunoda, one of the designers of the Sony MDR 7520, in NYC. This soft-spoken man is responsible for a number of Sony’s very best headphones including the legendary Qualia 010 ($2,400), a model that dates from 2004. That one had extraordinary high-frequency response, all the way up to 120 kilohertz, making it a good match for high-resolution audio.
Excerpt: Sitting pretty at the top of Sony’s critical listening range of studio headphones, the MDR-7520 offers an appealing combination of comfort, wideband reproduction and excellent acoustic isolation, as well as being lightweight enough for extended wearing. The tech specs indicate frequency response going down to an impressive 5Hz and extending to an equally impressive 80kHz, so we were naturally eager to put them through their paces in our studio and see how they fared.
