Read all the reviews, got them from Radio Shack because of the return policy.PROS: light, no cords, controls work well, mids & highs brought out details in some songs that I had NEVER heard before.CONS: severe drop outs, especially outdoors. Unfortunate because I wanted to use them while bicycling (they also fit well under my bike helmet). Motorola must know this because they now include a little flyer in the package warning you of this, and telling you to move the phone into the "Optimal Bluetooth Experience Zone." LOL. This is about between your navel and your shoulders, according to the diagram. I still had drop outs outside with the phone in my shirt pocket. They also got a little tight on my ears after 10-15 minutes of wear.OK, so they are going back to the Shack. I am back to my wired headphones with an MP3 player. *sigh* I had such high hopes. They didn't sound too bad in my office with the phone on the desk, although I got drop outs with the phone in my pants pocket and I rolled under the desk. Might be OK for some folks in limited use, but for full retail I can't justify them. Good luck.
