I'm certainly no audiophile so I won't pretend to be. They sound great. Awesome bass, good mix of highs, but beyond that I'm a fish out of water. The comfort however, is something I do know. These are pretty horrid for long term listening. I can go about an hour before I need to take them out. They're uncomfortable overall, poor design imo. They also refuse to stay in the ear, often slipping out when I'm not doing anything (working at my desk). What really sucks is they Comply doesn't have any eartips specifically for the DM008K's, so universal will have to do. The included foam tips are terrible, no saving grace there. I really wish these would've come with better ear tips, I feel like that'd have made them a much better product.
