The sound quality on these is okay, but the end of the right earbud started popping off (not the rubber part, the end-cap of the speaker enclosure, itself). Now, the end-cap has completely broken off and gone missing. I keep them in a satchel and they aren't banged around or compressed at all, so I'm assuming it was defective to start with. They were fine for the price, but buying a new set of earbuds once a month isn't my idea of money well spent.
