The reviews here sound so wonderful, if only the earphones matched!I simply don't get what everyone else is talking about. These are just wretched; clear, I suppose, but no bass at all. (zero!)I much prefer the originals that came with the iPod. Buy 4 of those instead.They were a gift at christmas and so the return window timed out. Thtat's a whole LOT of cash to be wasting.2.5 stars for sound quality, 1 for service.
