When would you listen to music on a phone or potato - very bad. If the price is not worth even bother to send the stuff back! Buy for years the Sony MDR-E 818 for 9 - these hold then exactly one year - Top Performance! - When I wanted to order this time were the Sony MDR-E 818 briefly at 18 - then I foolishly resorted to this cheap version Sony MDR-E9LPB - a serious mistake!
