How long is the battery life when Using Bluetooth?

The battery life is very good on these headphones. I bought a huge packet of HEAVY DUTY no-name batteries (not alkaline) from a hardware store. It takes 2 batteries and I probably mow the pasture 3 or 4 times before I have to replace them and it takes me 6 hours to mow, so doing the math, you will get about 24 hours of music off a couple of cheap batteries before you'll need to replace. I would assume you will get much more if you use alkaline. An outstanding feature is that long before the batteries go dead, a woman's voice comes over the radio and says LOW BATTERY, so you get a heads up to change them out before they die. Another feature is that after many hours of use, the unit will check to see if you are still listening and will prompt you to hit the volume button in a few seconds or it will shut off on it's own to save the battery.

How long does the battery last on a full charge?

I can usually go about a week and a half on a full charge. I'm really good about waiting until the battery is really low and then doing a full charge before unplugging it. I listen about 7 hours out of a 9 hour day. It takes a long time to charge.
