Ok I'm onto my third set of these now. Why do I love them? Because they sound great, look good and I can, unlike most other bluetooth headsets, run in them.
The Battery life isn't the greatest but I suppose that's the comprimise you make for this form factor. Main problem is they don't seem to last the year before I had to send them off to warranty. The buttons seem to jam after time and cease working. When this is the volume increase button you can see the problem!
Also don't lose the ear buds because they are vital for a good fit and sound. For some reason Motorola don't sell them separately. Without them the headphones are junk.
Also they don't take well to be stored in your pocket because they are so thin they can bend easily and break, if only they came with a protective case. So I wear them on my neck but you run the risk of losing one of those priceless earbuds!
But overall these are still the only choice for me as far as BT headphones go.
