Hello @Shanling first of all. I absolutely love the UP2. It has replaced several devices by doing multiple things well and sounds amazing. So, thank you for a great product but I've got one problem. I've got a Huawei P20 and everytime I connect the P20 Pro to the UP2 it defaults to HWA codec which has a tom of problems. 1. Constant signal drop (even with Wifi turned off) and 2. The signal constantly gets static and harsh noise interference misxed into the audio signal. If I force the phone to use LDAC all the problems disappear. So here's my question: Do you know how to force the pairing into LDAC? I've enabled developer mode on the phone but I cant find a way to disable HWA / LDHC . Any help would be appreciated as I have to manually force the LDAC connection through developer options each time I connect.

Interestingly I have the same phone and have no issues with HWA on the UP2 (I did have that issue on the BTR3 however).

Tried the UP2 with my computer via BT. I hear clicks when AptX LL is enabled. When disabled, the audio is clean.

Please what system, what app, what BT transmitter are you using?

Can you try it for comparison with other computer or android smartphone?

On an intel Skulltrail NUC i6kyk. On Netflix or just youtube via chrome. Windows 10 1903. Can't tell Aptx LL with cellphones as no phone has Aptx LL.

I got my UP2 this week, and it's fantastic. Its sound and driving power are really good — very audibly beyond what I was using before — and I love how easy and fumble-free the control wheel is compared to buttons. Very, very fine work, Shanling.

I got my UP2 too. Sound quality is great, but the microphone is a bit too noisy.

I was hoping that FIIO app would turn off HWA phone-wise, but it only did so for BTR3 - HWA sounds great in general, but there are occasional hiccups.
Really looking for a way to disable HWA.

I checked with a smartphone, everything is ok. It turns out that the problem is with my transmitter, thanks.

Glad to hear you sorted it out.

We were little nervous about putting all controls into one wheel, since everybody is used to bunch of buttons, but so far feedback seems to be very positive.

For microphone, you mean you are getting in too much noise from background? Or catching wind? Or some hiss?

Will try to put it as task for our software team, if they can advice some way how to disable automatic HWA connection on phone.

When I speak, my voice is always recorded with a lot of noise, as if as someone is constantly touching the microphone. There is noise even during quiet time - the background isn't "dark" enough.
During the test, I set still, with UP2 clipped on my shirt.

Avantree Clipper Pro does a much better job - blacker background, natural voice timbre.
Maybe you can use it as a benchmark for UP2.

My thoughts on the UP2. Very solid little unit!

Yes, it's one of functions of CSR chip.
