The only downside to these headphones are they are completely made of plastic, so if you rough on headphones I probably would stay away. Other than that they are great, easily foldable, great design, cheap, and they sound great.
To people that worry about bass. I read a couple reviews that these headphone had no bass or they would distort when turned Up loud. The only distortion I've heard is due to some of my poor quality music not the headphones. Tip also is to turn the EQ setting to off on your iPod, sounds much better
In whole buy them, now
