Reddit mentions of FosPower (4 Inch) 3.5mm Male to 3.5mm Female Auxiliary 4-Conductor TRRS Stereo Audio Extension Cable [24K Gold Plated Connectors]

Perfect. Yeah, something like this should do the trick. I don't know about the quality of the particular one I linked to, so make sure to check them out yourself.

Don't know if it would solve your problem, but I ordered this TRSS cable to force the DAC into high impedance and it sounds much better. But in general, I have no idea what I'm doing with this phone, and probably should have gotten a Jitterbug. So take my advice with a grain of salt.

Edit: XDA fiscussion: Different modes in the Quad Dac?

Edit2: You may be able to find a TRRS cable at Sam Ash or Guitar Center locally at most certainly an inflated price.

Yes. I bought this one: https://www.amazon.it/gp/product/B01552UGSS/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 and it works. You have to do the following: 1) plug extension cable in the phone without headphone 2) insert headphone 3) enjoy

I got one of these in order to fix it, had the same issue:

Will prob get it fixed via warranty the time i change phone, too much of a hassle atm since I bought it from ebay (asian version)

Yeah I've had a commuter on my past two phones. I like them, but they are a bit bulky. I also feel like they may have gone down in quality. My first one on the Droid Charge was rock solid and the plastic/rubber didn't peel away or crumble. The one I had more recently seemed like they lowered the quality of rubber or plastic they use because it didn't feel as nice at all. At least not nice enough to justify the cost.

What I'll probably do it get a nice one I like, and get something like this

I'd rather recommend a short extension cable, like this. Barrel-type adaptors will put unnecessary stress on a phone's headphone socket.
