While the battery life on this device is really great (lasted my 12 hour shift on a single charge) it seems to have failed about two weeks after my initial purchase when the watch has been going on and on reported that they are in TF mode. Sent back and exchanged for another. Same problem but only one day after receipt. I ended up returning it and buying a whole different brand that works great (except the battery life is only 10 hours. But I just charge it up during my lunch break and I'm ready to work the rest of my shift). With both brands, the sound quality is EXCELLENT! The volume can be very loud when needed. Of course, this consumes battery power, but you can also charge it while playing. The value for money is excellent. Twenty dollars for a small, portable, yet powerful speaker is good value.
