Cons: This thing hurts! I messed with it hour hours trying to get it to fit right and the best I can do, after an hour or two of use even with it's soft little ear piece just hurts to wear. It's a little quiet for my liking too.
Summary: I like it alot better than my wifes jabra which always sounds airy. but the battery life is random its not lasting all day on standby or I would have given it five. Other than that the sound is great and people cant tell im on a head set.
Pros: Its very clear had no problems pairing it with my razr. Very light weight and it fits in the ear very well.
Cons: Battery life is random. I dont believe the standby time the unit will not shut off and the light keeps blinking it looks like lighting in a dark room. (fixed with a sharpie)
Summary: This headset is probably the worst one I've used. I've had many SonyEricsson headsets, and currently I ended up using a free one that I got with my order of other stuff from office depot. That one lasts much longer than this one!
Pros: Made by Logitech, a well known company
Cons: 1. Headset sits on ear very loosely. Feels like it's falling off, constantly 2. Big, compared to other headsets 3. Doesn't hold a charge. Standby for approx 20 hours, w/o any talk time!
