Summary: Bulky keyring unit but very, very convenient and completely eliminates all those irritating tangled-up wires when you drag your MP3 player out of your kit-bag or the vulnerability of winding flimsy cables around your MP3 player.
Summary: I bought these headphones 2 years ago from a shop in New York and was very pleased with the quality of the sound, design and comfort.Unfortunately due to a fragile cord they stopped working 2 years later, but still I think they were a good buy.

Pros: neat and tidy with good sound production
Cons: the retractor can sometimes be annoyingly in the way
