It uses batteries (2). Last thru 3-4 movies. Works in car, have not tested range, mostly because there is no need to. Product is very nice for the price! Recommend purchase over OEM set.

They didn't work with anything we had in the house. When I discovered this it was to late to return. So I gave it to a girl who could use them in her father's van.

I returned mine it only lasted 4 hours on a charge, so I don't know anything about the warranty . I buy Plantronics m70 or m45 they are 11 hours and charge in 2 hours. Range is about 30 ft.

I have never fully discharged it so I can't say how long a full charge would take. I recall that the first charge took under an hour. However, I have used it for well over 4 hours without a charge and a re-charge takes about 30 - 45 minutes +/-. I use a standard charger not the USB port on the computer. Seems fast to me.

I am not sure but this battery takes about 8 to 10 hours to be fully charged from a labtop USB port so this may not be feasable

Battery life is pretty good. I like it because it is rechargeable. Just plug it into an outlet.

Hi Jack,I bought this for my wife for Christmas. It is charged through USB only, which is a problem for her because she wanted to use it from her iPad. It works OK, but if the battery gets low she can't recharge it without USB.

I can't give you an exact amount but the unit must be plugged into a POWERED USB port and not a regular usb port. Therefore, there would be some minimal battery drain. It is well worth it tho, as I can hear "things" from the computer so much better now.

I use it at school. Fully charged, it can last me 5-6 hours or so, depending on if I shut it down, or just let it sleep

Hi Robert, connecting the device to a USB port will only recharge the battery. However, connecting via a Bluetooth dongle will work. Hope this helps.

The most I have had battery life is a little over 2 hrs. If you charge it and don't use it right away it will die. But honestly for the money its a good price. Hope this helps.

Hello Alex I charge it with my computer and from my Anker external battery (using the 1A output) but I guess any USB port will do the same...Thierrywww.tgmdev.be

It's pretty good... I got up to 2 days use with mine without charging. And when I gave it to my friend in Africa.. He never complained about battery life despite the fact their wasn't steady power supply where he lives.

I've charged the battery from an electrical outlet with a USB adaptor and that works. I haven't tried charging it from the USB port of another device.

Don't know, but battery life seems pretty long...I've used several times without need to recharge. Sorry I can't be more specific.

I cannot attest to battery life. That would depend upon usage. The entire length of the unit is 2.75 inches.

Battery life is pretty good... A whole day if your actually using it.. I've left it sitting and it's lasted around 3 weeks without usage on one charge.

It comes with a USB port charger. I have found battery life to be very good!
