Headphone jack bug?

Hello. New user with an input issue

I have been using OP-1 for about a month and no problems other than a couple of crashes.

But today I inserted my headphones as usual and the OP-1 responded as if I’d inserted a Mic into the Mic input, with the case reacting ‘live’ to touch. I rebooted and it didn’t happen a second time, and it’s kept clean and not dusty, so I’m fairly sure it’s not a mechanical problem.

Any ideas?

If it only happened once I’d chalk it up to a weird bug. Mines glitched out plenty of times over the years.
