I bought this after my previous Bluetooth headsets (a) stopped working, entirely, (b) had such terrible sound quality conversations were impossible, or (c) were stolen. It is by far the best headset I have used. I can hear conversations clearly without pressing the earpiece into my ear (which defeats the point of the headset) and people on the other end report that the conversation actually sounds better than using my mobile alone.Pros:- great two-way sound quality- reasonable comfort- light-weightCons:- buttons take some getting used to- sounds/signals take some getting used to- a little large- battery life is shorter than some headsetsThe cons list may seem long, but if you are looking for a reliable headset that offers superior call clarity, especially on the road, this is your best choice.
