I am running into same problem. Similarly, Fiio is not replying. Is there any compatible battery we can use? Or any LiPo that match the voltage will do?

that is the screen, Q5S will be disconnected once "Confirm" is pressed. I need to remove the device, then pair a new device again. This is what I have now, can't even select the codec.

using Fiio Music app on Xiaomi A1. Anyway, changing codec from developer option doesnt change anything. Connection is still ALWAYS SBC as indicated in Fiio Music App.

Connected to Q5S using a Mi and Huawei phone. Everytime i tried to change codec, and press Save, the bluetooth connection died just like that. There is no way to reestablish connection again other than remove Q5S from bluetooth pairing, and create a new pairing, all over again. Therefore, codec...

This Fiio App to control Q5S, is not for iPhone and no luck for Android, right?

That is about USD20, other solutions on eBay cost a bit more than USD10. Not sure how they compared, some recommendation from existing user will be good. Point being, I got CL-06 from Fiio thinking of a nice set up. Have never thought of a situation where I need to buy even more stuff to make it...

I can, but it is putting too much pressure on them. Either of the cable or either of the socket is going to break extremely fast.

Recabled my ER4 to 2.5mm balanced some time ago, bought Fiio CL-06 together with Q5S, thinking I will have a formidable walk-around set up with my MI A1. But.... turns out CL-06 cannot coexists with 2.5mm balanced cable. Sigh...........

Just got my M5 and have been using it for an hour. Preliminary observation - Currently using folder browsing to play songs. Every time after power up, M5 wont be able to recognize micro SD card. Need to manually remove the card and reinsert, wait for 5 seconds, then the device can recognize it...

from the spec itself, should we expect M11 to have better sonic quality compared to Q5/Q5s? specifically about detail and instrument separation etc

Anyone listen to this and also ER4XR? How do they compare to each other?

Any suggestions where to get the corresponding mmcx connector for ER4XR for me to diy a new cable?

I am a long time owner of Er4p, loving it. But just a couple of things about er4p that made me ordered an Er4Xr, the extra bass and the "replaceable" cable. Reading this long thread made me realised it isn't so replaceable after all. Having Fiio X5 III but still can't take advantage of the...

that works flawlessly!! thanks!!!

I am using Windows 10 on a Dell Vostro 3400. Installed the official DAC driver and it reported "failed". Obviously it doesnt work as a USB DAC. Any suggestion what i can do?
