I'm buying two more at the price I payed for one: One to leave permanently on my backpack and one for a spare in case I lose or break my current pair. I lost the first pair on vacation on Kauai (If you found them, brag, call 'eh?) Second pair I smashed in the car door when the the earpieces fell out of my pocket. Even being careful, the long cord lets the earpieces drop to the ground (I'm 5;9") and makes it easy to step on or lose the earbuds. Somehow, the on/off button is a target, and anything near my chest seems to find a way to turn on my audiobook when the earpieces are stashed. No fun trying to find my place in the book. :-)
Now for the good stuff: The earbuds come in several sizes, and even with my small ear canals they are quite comfortable. The buttons are quite responsive, and can do cool things like turn a recorder on and off, and operate the iPhone's camera remotely. Usually I will think, "Can it control this app?" and more often than not, it can, at least for on and off.
Sound is good, but I am no audiophile. I have friends that are, and they buy these after hearing mine, so I guess they're okay. I'm very happy with mine, and I would be an idiot not to take advantage of the deep discount. If you get them, enjoy.
