My Sennheiser wireless headphones had taken to cutting out (no lights on the base-station) after several hours of use. Unplug it and leave it and they’d be working next day. Since the cheapest part I can replace is the PSU, that’s what I got for £13.75 with next day First Class post delivery. The new wall wart is a switching unit whereas the old one was a heavy copper transformer. It’ll be a while before I know if I’ve cured it as it was an intermittent problem anyway.
