@FiiO - would be great and if it possible to make in future option to turn off lighting when computer goes to S3 Sleep State (my Razer Huntsman V2 RGB keyboard turn off lighting in S3 Sleep state) I make option to turn off light like you showed in previous post SW on Mute button, but not...

Great thank you, waiting for solution, without solution fix try to use it at night :) By the way, is it possible that firmware to KB1 was badly flashed via jade.audio website ? Or it's not possible if device work fine exept this strange volume behavior. Another question, for what this KB1 have...

More investigations with tihs problem: Easy to identify this problem, when you rotate a volume knob from click to click it work fine, but when you will rotate it from click to not click and let it go in half between clicks, then it will itself increase volume to max or decrease to min itself...

Thanks, right I fixed it, I have select some certifcates from site and this was cause a problem, solution is to Cancel any certificates and site is load fine. @FiiO - after upgrade a firmware on website jadeaudio.com now my volume sometimes increase or decrease itself to maximum or minimum when...

Yeah great move FiiO, you discontinued better much premium produckt and now produce only plastic cheap light version :clap: One more thing this site do not work anymore, now https://keyboard.jadeaudio.com/device 403 - Forbidden: Access denied. You do not have permission to view this directory...

@FiiO - why KB1 aluminium is not available on Alliexpress ? Also, can you make keycaps with signs Play/Pause, Previous, Next.

I made built-in microphone test in Qudelix 5K, compare also to FiiO BTR3.

I do not think lossless is necessary to anything. I can't even tell difference between AAC VBR 320kbps and FLAC. Where LDAC can go up to 990kbps :) so. Lossy compresion is 100% fine not noticeable for anyone , problem is loudness war this thing ruin songs quality.

I'm using now EQ in LDAC with Qudelix 5K and it's perfect fine for boost a bass on earbuds for example I use it with VE Monks+, and nothing change in clarity of sound after EQ them on bass, 31, 63Hz.

^this is not perfect solution, I prefer built in EQ in device memory, because I pair it with few devices also with PC. FiiO is a joke with this EQ for LDAC.

I think 5K its too new to release new model :)

Ohh nice, I do not know that, thank you for info.

Thank you for info. Just received it from AudioHeaven.eu in Poland, for fast test now connected to VE Monks+, finally I will pair it with HD579 or HD600. Very small, even smaller that BTR3 on high I quess. Firmware upgraded super fast via OTA, EQ work in LDAC which is great. Would be great to...

^ There are few things to improve BTR5, most important are: - EQ support for LDAC !!! - lighter construction - better BT range like Qudelix 5K - aptX Adaptive support.

How do you think any chance to implement via firmware support for native DSD ? BTR5 support it and use same or very similar components. Why 5K can't ?
