Our Verdict Despite impressive looks, these Koss's are poor performers For Generous bass Against Hard, thin sound uncomfortable to wear cumbersome Reviewed on 22nd January 2010 Compared to close rivals, these cans from Koss feel heavy and cumbersome. The rubber ear pads aren't very comfortable: ironic, because these headphones are comfortably the poorest performers we've seen for a while. Listen to Eminem's Same Song and Dance and it sounds like it was recorded from the confines of a size five shoebox: there's a hard edge that renders long-term listening impossible. The only saving grace is that bass is generous, but still, they're way behind their rivals See all our headphone Best Buys More after the break Follow whathifi.com on Twitter Related News Best headphone deals - in-ear, over-ear, wireless and more Tue, 23 May 2017, 05:42pm The best What Hi-Fi? deals of the month - May Fri, 19 May 2017, 05:38pm Sennheiser reveals special edition Pink Floyd headphones Wed, 17 May 2017, 12:51pm The 10 most popular reviews on What Hi-Fi?
