Line 6 UX2 Headphone Jack Trouble

[LukePukeDuke1]

Hi, I've been searching everywhere but I can't seem to find an answer for this problem that I'm having, I really hope someone can shed some light on this. I've been having some trouble with my UX2, I should preface this by saying everything's working properly outside of the fact, input levels are normal, it's reading a normal output level, etc. So, my problem is that when I plug my headphones into the headphone jack (through adapters, yes) fully, the sound is so quiet and only really comes through the left speaker. When I plug in the headphones about 3/4 of the way in, they work perfectly fine like they used to. I suppose I could just record like this, but I'm worried that this may not be accurate sound, and I'd just like the sanctity of mind to know that I'm hearing accurate playback. Can someone please fill me in on what's going on, if this is a hardware issue, a jack issue, if this is a huge problem or not. Thank you.

There’s a good chance you are using a mono adaptor for TS (tip sleeve) for a stereo jack, TRS (Tip Ring Sleeve). Or possible headphones with a mic.

Could something like that work fine before hand, though? These were working as intended not too long ago, would there be any reason for them to be acting up like this out of nowhere?

That is strange, can you confirm what type the 1/8 inch jack and adaptors are?
