Dang. I bought a pair of the aluminum ones shown here for $13...like 4 years ago (for 3 times the price) when they were new? The bass isn't as intense as Skull Candy and some others, but the sound is clear and nice. These are the only no-tangle earbuds I've had that truly don't tangle.
In other words, this is a STEAL. If mine weren't still going like new, I'd be in for more.
