Chosen Solution

I had a perfectly good set of Bose Quietcomfort 20 ear buds, battery working well, charging quickly and lasting ages. Whilst in Thailand and charging the battery there was an electrical storm and a power outage (presume surge). When I tried to use the headphones there’s no charge in the battery and it won’t charge. There’s no noise reduction when I turn them on. The green charging light comes on when they’re plugged in but even then there’s no noise reduction. As soon as I unplug from the power the green light goes off and the battery is dead. Any suggestions? Thanks, Bill

@billwatkins start by replacing the battery. It may no longer hold a charge. Update (11/08/2017) This video and part two of it on here should work for that. Different model same idea. Definitely not an easy job….
