I does not have any issues when transmiting music from Fiio to earbuds via aptx protocol, just with SBC.

@Fiio, do you have any thoughts about mentioned bluetooth SBC issue? Is this a software related problem, or failury units? I have a couple days left for a return and need to know as soon as possible if fix for this issue will be delivered soon or not. Otherwise, I will go for a Shanling M0 device, sorry.

Edit:

Tried dowgrading BT firmware to 1.1.1, device software to older. It did not work. Tried 24 bit flacs and regular vbr mp3 - no matter what file is played via SBC protocol, it hissess a lot.

i have the same problems using SBC bluetooth earphone, been waiting for the firmware updates for months, so rarely use the M5 since the day i purchased, fiio really slow in updating the firmware, many audio enthusiasts in my country suggest me to replace it with shanling, they update the firmware more frequently, so @Fiio please hear your customers complain and give the solutions, so they don't regret buying fiio devices.

We have reported to the engineer, but it may still take them some time for checking about that.

Hi, I recently bought the M5 and update to latest firmware. I also have this problem with my Sony WF-1000XM3. I try to connect my JBL Live 100 through 3.5mm it works just fine

Dear user,

Can you connect to the headphone via another Bluetooth codec and check again?

Dear Fiio,

Is there any plan in the future from Fiio to update M5 Bluetooth Firmware to resolve this SBC codec problem that cause the distortion and grainy sound?

Thank you

The distortion appears when using SBC codec, aptX works correctly.

I also find the sound quality to be bad with SBC earphones (Bluedio T-energy and Mifa x5). I understand that these are budget earphones but the same earphones sound much better connected to a $15 Benjie S5 or a cheap Cubot Smartphone than they do with the M5.
With the M5 everything sounds very compressed with poor splashy treble and little bass.
This is very disappointing as I prefer to use bluetooth outdoors but the poor sound quality is stopping me from doing this.
Hopefully a fix can be found soon.

We have reported this to the engineer. But they fails to reproduce about that and understand well the bad sound quality you feel, so it may not be easy for them to improve currently.

Thanks for your response.
My M5 has now developed other more serious problems for which I have created a new thread.
These include getting stuck on the boot screen and problems adjusting the time and it not being saved on power off.
These could be related to the same underlying issue. I am mentioning them here in case anybody else with the bluetooth quality issue sees them as well.
