I have been comparing, I have to say my first impression is this is a winner. Beets the two similar devices (Es100 & BTR5, My BTR3 broke) I have hands down. Added some updates from wslee, thanks man.

Thanks! I searched their site and couldn't find anything.

Using the device via LDAC performance mode.

Sony ier-z1r has well represented bass. Voices and Treble are harsh.... But interestingly filters do make a difference on this device, and they can reduce this treble harshness.

App in android is not beta feeling at all. Easy and responsive; not frustrating at all.

What is that big T adapter sticking out of it?

Sorry to be that guy:

so, on iOS or better, mobile application, if connected, does it get the data through the cable or it remains on bt? I’m interested since I think this little fella is like the bt5 though with a bit more guts and powa. I’m considering it

My DD-HiFi 4.4mm to 2.5mm balance adapter.

Since my official Sony cable is 4.4mm. And this Sony iem is not sensitive enough to need to worry about adapter impedance.

Same amp's so yes. I don't know why but the SQ seems better than the BTr5 to me in the mids mainly. Better battery and better SQ no screen so a little less easy to used but once it is set up who cares. The app is not as good as the ES100 but it is still in development. Been listening to this and playing most of the day now and it is really growing on me.

z1r, damn man talk about baptism of fire , The Mids and high detail due to that natty tweeter are going to be a bit harsh. Bit extreme for a BT dongle . I have been trying to get a pair of Z1r's in the UK. non in the country as far as I can tell, wondering if Sony are going to update them soon as they dont seem to be making them anymore... Opps sorry off topic.

Yeah, off my other gear this harshness is not there.

Is the latency acceptable on pc when gaming?

You'd have to resort to using it via USB if you would want to game. Even just with movies and video, delay is noticeable for me using Bluetooth and aptX.

You would be better off with BTR5 and Aptx-LL. And a usb Aptx-LL tranceiver.

With the Samsung s20 Ultra it at 990Kbps it stutters but not often, it is OK at 660Kbps though. I should add Im in an RF noisy environment.

Their support told me:

Qudelix Support qudelix3 hours ago
Please note that Samsung smartphone usually has issue with 990kbps.
It works at 990kbps, only when the screen is off.
The 660kbps is the best tradeoff at the moment.
Samsung device sometimes doesn't work properly, when you change the bitrate or LDAC sample rate in the developer option.
In that case, you will need to stop music and then play again.
Thanks!

Which I think is a bit of Horse Sh1t btw. I have an issue screen on or off.

I've always had issues forcing my Galaxy S9 to connect to my ES100 via LDAC 990kbps. Will see how it works on the 5K when I get it but I expect it to be the same.

Just picked it up
SQ is good. Should examine it more. It seems to sound more dynamic than my ES100
Although, initially LDAC 990 was stuttering a lot (Samsung S10), a minute later it became smooth (have to check it more)

Sounds great with my balanced FH7 and my single ended Beyerdynamics T5p

I have been told the stuttering gets better when the screen saver kicks in.
