Who cares what they sound like? They're only 3 bucks!
Even better than that. Theyre only $3 and DO sound good. Enjoy full-range sound from the 10mm drivers, with extended bass and good mids and highs. Enjoy the convenience of the in-line microphone and play/pause button.
Don't worry, just because they are cheap doesn't mean they are cheap. The tangle-free flat cable will allow you to concentrate on what is important, the music. And the money you saved.
