These are nice headphones but I'm downsizing a bit on equipment. Used, but not hundreds of hours - more like maybe 15-20 total.

Ultrasone is a fine brand, and these phones give you a detailed stereo soundscape that seems extra-dimensional with the S-Logic design. Nice bass response that is solid but not muddy or overwhelming. I'm a bass player and I often reached for these if practicing only with headphones. But they also sound good just plugged into my iphone listening to mp3s. A great all-around pair of headphones.
