I have a Nokia BH-214 which I use occasionally which is similar to the Jabra, you can plugin normal headphones if you don't like the ones it comes with. The speaker is in the square where the headphones plug in to. The sound quality is ok, but when riding at 20mph the mic will pick up a lot of wind noise, so you'd have to slow down. Like the Jabra headset if any music was playing it will mute it during a call. They both have the play/pause, skip, back and answer buttons. I've mostly liked it, but again don't really use it all that often. The earbuds don't get in the way of the staps on my helmet which is nice.

To add to the flamewar, the argument for needing to hear every single sound is totally useless to me. I can't tell what lane a car is in by the sound, how close they are with any useful kind of accuracy, if they're driving inside of lane or drifting outside of it, not to mention that wind noise makes it quite a bit worse at 18mph+. Mirrors, on the other hand, are actually useful.
