I don't normally leave reviews unless I am either extremely impressed or extremely disappointed. This is NOT an impressed review. I bought my first pair two months ago. Overall, the range was not that great, but it was not all bad either. If you were in an open room with no other kind of interference, you could possibly get about 20'. However, if there was a wall somewhere in between, forget it. You MIGHT get 10'. If there was a "warm body" (or even part of a warm body) between the phone and the earbuds, you could also forget about reception...this included an arm or a gut. (If I had my phone in my pocket and crossed either one of my arms across my chest or stomach, I got the annoying "Out of range. Trying to connect." message.) This frustrated me, but I put up with it.
However, after only about three weeks of use at work, I noticed greatly diminished sound/volume (phone calls, music/audio books) in the left earbud to the point I had to have the volume on my phone maxed as well as the separate volume control on he earbuds maxed just to barely be able to hear the audio. Because of my work setting, I typically only use one earbud, so I could have just switched ears, but I figured I must have just purchased "the rotten apple in the bushel." So, I returned them to Best Buy where the folks who helped me were absolutely wonderful, and purchased another pair of them. Unfortunately, I quickly learned that the range impairments were not limited to the first pair. Then, again, after only about two weeks, the volume in the left earbud became severely diminished in the left ear. I carefully performed a thorough cleaning the earbud to ensure there was no wax buildup instead of the usual wipe down every couple of days, but that did not help. So I switched to the right ear. After about two weeks using it, the volume in it became so diminished I could no longer hear it. Needless to say, I returned them tonight and went with a different brand. As I talked to the sales people about the different brands of Bluetooth earbuds, they said they have heard a lot of negative feedback on these.
