The highs are rolled off so much that my (really good) electronic piano doesn't sound at all realistic. I have compared it using a few pairs of very good headphones, as well as my somewhat expensive home stereo. This guy might handle power well without blowing out, and produce pretty good mid- to high bass as well (they still need a subwoofer for even moderately low bass.) But they are not accurate. I would return them but I am past the return date.
