"Battery life is a drain!"2.5 starson by EBRRBE
Pros: Size and compatibility with cell phones is excellent.
Cons: The battery life is advertised at 3.5 to 4 hours of talk and listening time. I got on average 75 minutes of talk and listening time. The right ear bud (which is where the battery is) heats up and is not comfortable at all. Expensive and don't last.
Summary: Sound quality wasn't bad but it wasn't great. I'm sure that 2010 will produce similar ear buds for the wireless market, so I would wait if I were interested in these ear buds. The IS800 are nice but offers only a taste of what most of us are waiting and wanting. Save your money and stick with your current set for now.
