Summary: Great sound, very difficult to use.
Crutchfield Customer Review (What's this?)
I had great difficulty getting the ear buds to stay in my ears, as they kept falling out. The wrap-around-the-ear cord made it worse. The instructions that came with the product are woefully inadequate. I have gotten the buds to (kind of) stay in my ears only after visiting the online site indicated, reviewing instructions there, watching a video, and finally, having a chat with a tech. Unacceptable. Without the extra research, I couldn't remove the sleeves (concerned about damaging the housing) to experiment with others provided that worked better. The sound was great, once I got the right buds properly inserted (sound had no base and was tinny otherwise). I give the product high marks for build quality. I would give it low marks for design quality if that category were available. The latter is made worse by the collective lack of understandable instructions. Net: the product is overly sophisticated for even the serious consumer. Important note: I'm a retired, former self-employed IT Systems and Management Consultant ... not the dullest knife in the drawer.
Pros: Great sound quality ... once you can get the right ear buds properly inserted in your ear, and keep them there (monumental tasks for me).
Cons: Difficult to use, exacerbated by terrible written instructions.
