I recently purchased my first bluetooth enabled cell phone and was really looking forward to using it. I purchased this earphone expecting great things. While others mention the AAA battery as a positive, I'm finding that I need to replace the battery at least once a week. I have had serious problems with echoes, both on my side and the side of the person I am speaking with. Also, the earphone feels floppy and doesn't fit tight against my ear. I am always concerned that it will fall off.So, even though I have only had the earpiece for 2 months, I am shopping for a new one!
