Try messing with wifi. If I remember correctly it's the 5ghz wifi messing it up.

You guys should post some of these suggestions on official forums. They are very open minded and open to ideas.

I actually got compliments on the mic from my gf. She thought it sounded a lot better than the BTR3 I had and my vmoda boom pro mic.

New update coming this week, Might include the PEQ.

Can't rename saved EQ profiles yet and there is a bug with the EQ where it shows 0 when you go back to it. It still works as it should and it still saves into the memory just fine.

Tbh it sounds like the same problem the guys with the japanese phones were having. I suggest you post on official forums, if it's the same problem i'm sure they can fix it as they fixed it for the japanese phones.

They are working on adding it next update iirc. Peq is top priority

No self powered USB mode yet but they're working on it.

I also have these same exact cables and they work with the 5k NP

https://www.amazon.com/gp/product/B07TPYSLBN/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 That's what I use, 3 good cables for cheaper than the one in that link.

I've tried it on galaxy tab s6 android 10. Galaxy tab s6 doesn't have a headphone jack, it used the 5k just fine for me. I had the 5k set to 48khz in the app which is why it shows that for my device capability.

I don't have this problem though I don't use foobar. I tried win10, usb + Amazon HD music/MusicBee/youtube music

That works when I do it. It sounds like you need to make sure side tone is disabled under the mic options. The SW is a bit buggy so sometimes I have to turn it on and then back off for it to truly be off. Give it a shot and that whole hearing the cable thing shouldn't be a problem anymore

Thats so weird, I'm super curious as to why there is a problem only on Japanese phone.

You must be another person who didn't choose express shipping ;(
