I'm not into an over-the-top base sound. I just want accurate equal sound. These are fabulous. Sometimes I get the chills when I listen to something really beautiful with them on. In fairness though, I've never owned a decent pair of headphones before. I specifically chose this pair because of the replaceable cord because that's usually what goes first. I sometimes forget I have headphones on because I'm used to wearing ear protection for my work. This tends to wreak havoc on audio cables.
They sound great whether you're listening to music or playing games.
These are absolutely amazing . I have the HD700 and HD850s along with several very nice audio technica cans for mixing and mastering and I find myself using these for most tasks most of the time. They are very comfortable with incredible flat uncolored sound quality unrivaled by any headphones at the same price point. The soundstage is very wide and very accurate. You can always trust Sennheiser to make quality gear.
I am a moderate audiophile and use these recreationally, not professionally. I am a passionate classical music listener and demand top notch reproduction across the range of dynamics of classical music. I don't have to have THE BEST, but I do require excellence, and these have it. The sound is realistic and balanced. There is very good reproduction of tone qualities. I have heard brighter sound, but in comparison that sounds artificially bright to me now. These are very comfortable to wear and do a remarkable job of blocking out ambient noise, given that they are not actually noise-cancelling.
