This headset has great sound quality (nobody knows I'm even on a headset), works well in windy conditions, and pairs easily with my motorola E815, as well as a Palm Treo 650.It is plenty loud for me, has a decent connection range (even through walls), and lasts for a long time (can't say specifically, but it invariably lasts longer than E815's battery with bluetooth on and that's what matters). The charger is tiny, but I'd still reccomend getting one of those combo chargers with interchangable tips available at Radioshack and the like; a bit easier than carrying around a separate cellphone and headset charger.Also, its small enough to be worn comfortably for long periods of time; I've gone three hours at a stretch and hardly even noticed its on. It fits nicely over your ear so it doesn't get too hot but fits snugly. It also seems durable; I keep it in my pants pocket with no problems.Overall, it would be hard to improve on this design for a functional, high quality wireless headset. I don't know what higher priced models could possibly offer, other than caller id on the headset.
