I am now on my third pair of headphones, I guess I am a sucker for technology.Reasons I love them, for some reason they seem to have better speakers than headphones with wires. They are convenient and easy to use. Great for the gym unless you are leaning back.Reasons I hate them, the band is cheap and cracks very easily (I have a medium head)The adapter is very heavy, and spins my IPOD, a pain when running through the airport.The head band is not adjustable, one size fits all does not work for some people.Outside of that I happen to like them, I am saddened that I am on my third pair, but I plan on sending this set to Logitech for repair instead of paying out of pocket.
