The battery in my ML 80 headphones only lasts for 2hrs of use now, but it is over 4 years old. I have never actually used the ML80's with the Nox, instead I have used them almost daily watching stuff on my tablet. So they have been recharged many hundreds of times. I guess that is still pretty good going really, though now it is time to replace the battery. It is a 3.7v 320mAh LiPo but I am going to upgrade it to a 600mAh as it will still fit okay. I guess I can't really grumble at £2.49 delivered?

I'll will be easier to just cut the existing battery wires and solder the new ones onto them.
