Note: audio quality tested with sennheiser momentum, v-moda m-80, sennheiser ie8

These sound really good for closed headphones: very good detail, good bass, fantastic mids, good highs without beeing too bright or harsh sounding. Jumping from v-moda m80 I found these more detailed and extended, expecially on the highs. The sound is also more airy and the soundstage more extended. I also owned v-moda m-100 and while I think both are very good, I find momentum best for rock genres (like muse, radiohead,...) and as all-rounder  while I found m-100 best for dance, techno and electronic genres.

When I received my M-80, the first thing I noticed was the premium packaging. Build quality is really great, these headphones have really a premium feel. Also the case is unique. 2 cables are included, one with only mic (compatible with most phones and players) and one for apple products. The cables are a bit stiff, I don't know if they will become more flexible with usage. After 24 hours of burnin, here are my considerations about sound. Currently I own also sennheiser IE8 so I will do a little comparison. Differences between IE8 and M-80 sound...
