Ok, so I have a conundrum…
I have a pair of Sony WH-1000mx4 bluetooth headphones, they have a built in DAC and amp but can also run ‘corded’ with a 3.5mm stereo cable. The built in amp works while connected to the stereo cable, but the bluetooth and other features ‘noise cancelling’ turn off automatically. You can also ‘power off’ the headphones and use them as a standard pair of non-powered connected headphones (which is my preference when listening to music).
When I use them as bluetooth headphones, the battery will last about 30-35hrs, pretty good.
However, when I plug in a source stereo cable and use them non-powered, the battery drains in about 6hrs. Heck, I could just leave them plugged in and turned off and 2 days later they will be flat. Not great, even though I don’t need the battery it should not drain that quickly.
Is it possible for the battery to drain via the stereo cable? Seems odd!
