What I like most about this headset is ironically the thing that bothers me the most as well! That is the fact that the earpiece goes directly in the ear, this makes it a noise cancelling head set which is great because I really can hear the person that I'm talking to. Unfortunately this also takes a little getting used to because the noise cancelling is only in one ear, so that you feel like you have  water in your ear or something. You will not want to walk around with this in your ear like you see people doing with other devices. As far as it staying in my ear, I've had no problems with that and so far no one has complained that they can't hear me. I especially like how light it is and because I wear glasses, this device doesn't interfere with my frames. I also like the sliding boom to open or close a call. All in all a very nice head set and I had no problem pairing up with the motorola Razr2 V8
