Query: Incredibly disappointing

It's no wonder they've discontinued this product. DO NOT purchase them, at any sale price, if bass response is at all important to you. They are comfortable and the clarity at the high end is decent, but the bass response is the worst I've ever heard in an earbud-style headphone. Even the slightest bass levels force them to distort radically and ruin the listening experience completely. The only possible use I could see for them is listening to audio books. Just awful.
