So i just got mine in the mail, and am testing them with my desktop (which requires use of a "small to big" or 1/4 to 3.5mm adapter) and the weirdest thing happens - the audio is all mid channel unless i hold down the mic button, then it will be full stereo. This won't do, as i hope to use these with my home rig as well as on the go. Any idea why? are there adapters that take the 3rd ring on the plug into account and let you use it as intended? P.S. tried these on my phone and tablet and they do sound great in other setups as long as i don't need an adapter, but once that use-case comes up they're kinda borked. Help a moron out, anyone? thanks in advance.

phylum_sinterThe problem is in the adapter, and there are only certain ones I have that work. The post on the headphones is TRRS and the typical adapter is TRS so things aren't lining up properly and you're getting a short across the mic ring. My first suggestion would be to plug the KSC's into the adapter that's connected to your desktop, turn on the music, and then you twist the post in the hole on the connection and see if that restores the full stereo sound. I have to do this every time I plug my PortaPros or my KPH30i's into my work setup. I have some adapters that work fine after the twisting, but some don't work even after the twisting or they work but will short when moved. I have a couple adapters from some V-Modas and those are the best. No twisting ever. The all metal ones I've purchased never work, but the gold ones with the black plastic ring work well (with the twist). These are the ones.... https://smile.amazon.com/gp/product/B00XAWQ4W8/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 You can also use this. It'll remove the mic channel, but you'll still need the 3.5mm to 6.3 mm adapter. https://smile.amazon.com/YCS-Smartphone-Headset-Headphones-microphone/dp/B00MV2PDCA/ref=sr_1_1_sspa?s=electronics&ie=UTF8&qid=1541980852&sr=1-1-spons&keywords=trrs+to+trs+adapter&psc=1
