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.

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 The best What Hi-Fi? deals of the month Fri, 22 Sep 2017, 05:18pm The 10 most popular reviews on What Hi-Fi?
