I still find directly connecting to my iPhone via USB to the Q5 sounds better than BT. On the go I use BT. But, for sit down listening sessions, it’s direct connect. Noticeably better in my case. iPhone 7/Tidal or Hiby App, (AFLAC or DSD),/ Lightening to USB/Balanced 2.5/SE846 Modded Blues.

Normally. Just followed the directions carefully. It was a bit confusing and frustrating. But, I printed out the directions and carefully completed it successfully.

Yes. I was able to finally get it all updated yesterday. It took me a long time to understand the process. Thank You.

I got it to work. Thank You. Both System and BT updated now successfully.

Bluetooth seems better sound quality wise. But, that’s probably the placebo effect on my part.

I wish FiiO would document a version history. Not sure what has changed in these updates.

I was able to finally get both the System Upgrade v.058 and Bluetooth Upgrade working. It took a reset on the Q5 to get everything talking to each other. I hope others are able to get theirs updated. Just follow the instructions very closely. I’m amazed it took me this long. Thanks for your help...

I did do that. I reset the Q5 with a paper clip. It now is working with the update. Thank you for the reply. I’m patiently waiting for the DSD light to come On now.

I get as far as this... and the System Uodate just stalls at Entering Update Mode. Then Error Message: Firmware Upgrade Failed

Maybe you could make a video to show just how easy it is?

I totally agree. I’m still trying to get it to update. I’ve given up. I’ll send it back to Fiio if I hear it’s some major update. Otherwise, I’ll keep enjoying it. Everything works well. So, I’m happy in that regard.

Trying to upgrade BT with your instructions. Trying to install USB DAC Driver. Can’t find the “Q1Mkii under the “Sound Video and Gamecontroller” in Device Manager after Executing the FiiO Wizard. The only thing under “Sound Video and Gamecontroller” is “Conexant ISST Audio” This is so frustrating

Same here. This is with Windows 10

It’s whatever Apple sends via BT on iPhone 7Plus. I’ve heard it’s AAC, which sounds good. Obviously when playing DSD with Hiby App there is a difference from USB and BT connection. Still a difference with AFLAC USB vs BT. Just my take. I avoid BT whenever possible.

My Q5 definitely has better sound quality through USB than BT. I only use BT when stacking is not convenient.
