Compared with my Audio Technica ATH-Pro500MK2 (38ohms), the MDR-10RC (40ohms) sounds quieter at the same volume (smartphone as source). But when coupled with a portable amplifier (Fiio E11), the MDR-10RC has very tight and defined bass, clear mids and highs. I guess its "anemic" performance with my smartphone is caused by being under-driven. The clamping force is softer (and more comfortable) compared to the Pro500MK2 (DJ headphones). I was surprised that the MDR-10RC sounded quite well with classical music, thinking that these headphones are meant for bass-heavy music.
