What reviewers say

MusicRadar and SoundGuys agree the MDR-7506 is a sturdy, revealing and affordable tool that still works well for mixing and monitoring. Both found the heavy coiled cable a nuisance; MusicRadar found the leatherette pads a little cheap, while SoundGuys found them uncomfortable with glasses and their treble prominent.
