Summary: After too many problems with sein***er, I decided to go one step up and invest in something more durable. Pros: - Impressive overall quality. - Great comfort given by those "click" buttons - Durable! Really sweat resistant! - Sounds good.
Summary: Great, but a bit cumbersome to adjust. I have another in Ear klipsh however bought this one as it is a rugged model. Sound is pretty close from the non rugged I have. But adjusting it to your ear is the weak point to me.... Sound blows the competition away.
