LF 64Audio U12T Must be willing to ship to Canada. PM me price. Cheers

It's not supposed to back charge, but there is definitely power drain going on, even with OTG cables (happens on every device that I own). The workaround I found that works is to first turn on your DAP and the Q5s WITHOUT the cable plugged into either. Plug the cable into your DAP first, and...

Got two cables made by Null Audio with the ER4 specific MMCX connector and they're great.

I've been waiting 1+ year for this. Soon please :)

So I finally got my R6 back after shipping it to HongKong to get it fixed. Whole process went perfect, so I am very happy with that. Just a quick question, maybe I am missing something completely: I got the device back with the latest firmware (I had not upgraded to Oreo prior) and it seems...

The workaround if you don't want to disable charging completely is to turn on the Q5s first, then plug in the cable, then plug cable to phone.

Despite what this picture says, there is definitely back-charging going on when I use the CL06 cable with my devices (Hiby R6, Hidiz AP80, Huawei phone). I'm not talking about the device showing a notification that there is back-charging, the battery drain just happens noticeably faster. Also...

Indeed it would be great if Fiio could just release a firmware to fix the issue instead of having to rely on a somewhat inconvenient workaround.

On a side note, I was wondering whether you are able to connect the Q5s to the AP80 by Bluetooth? For some reason, my AP80 absolutely refuses to find the Q5s (even though every other device can pair with the Q5s just fine).

Someone posted the solution a few pages back and it's worked for me: 1) Turn on AP80 2) Turn on Q5s 3) Plug-in cable Done. If the cable is plugged into the Q5s before you turn it on, it will draw power from the AP80, but if you do it in this order, everything is fine.

Hey, just wanted to thank you again for the help. I ordered the parts from Lunashops. Now waiting for them to get here and see if I can make it all work... :fingers_crossed:

I'm having the opposite issue, where my AP80 absolutely refuses to discover the Q5S through bluetooth (even though my phone, laptop, etc. all have no issues, and the AP80 can discover other devices just fine). Any ideas anyone?

Thanks, very helpful! If you don't mind me asking: any Ety specific MMCX adapter/moddable prebuilt cables you would recommend (preferable on Amazon/Ebay). My biggest fear undertaking this project is sourcing low quality material, and I would assume that you have a good idea of what works well.

How would I go about building myself this kind of adapter? I'd also be interested to learn how to build my own cables, the materials needed, etc. if you don't mind helping me out...

Can't get line in input to work no matter what... am I doing something wrong or do I have a defective unit? :frowning2: I just did more tests... if line in end is halfway plugged in, signal comes through fine. As soon as I push it all the way in, no more signal.
