I guess Sennheiser assumed that only DJs would use these phones, in bass-heavy dance club environments, because they completely neglected the low-end response from the phones themselves. The mid-range (vocals, etc) sounds excellent, the highs are a tad bright, and the bass response is non-existent. If you listen to rock, dance, hip-hop (basically, any type of music with pronounced bass), you will hate these phones.On the plus side, I guess they are comfortable. Sennheiser should take the headband from these and use it to replace the horrible headband on the 280 Pros, which sound great but are horribly uncomfortable.
