Sounds very good, however it's no a tight fit,
Verified Purchase(What is this?)
This review is from: Plantronics M55 Bluetooth Headset (Accessory)
Works wirelessly with IPhone 4S using IOS 6.01 software which means you can listen to Internet radio etc. it's light, sound quality excellent my only grumble is that it feels loose in-ear. By that I mean if you push I slightly the sound improves further with better bass response, but then it slackens off again when you let go. It doesn't fall to though in fairness, as the gel cover has a piece which fits inside your ear, anchoring it effectively. It just "feels" loose if that makes sense!
