FIIO Q15 DAC and Headphone Amplifier Discussion & Impressions Thread

Cheers. One thing that's been lost in all my trials with attempting to use the Q15 USB connected with my phone is how damn great this thing sounds. I've managed to use it Bluetooth connected and USB connected to iPad.
I can confirm that with my S22 Ultra I have to set the tiny switch on the bottom of the Q15 to Phone Mode On, otherwise no sound at all.

I hope that helps!

Hello, please turn the “PHONE MODE” switch to "ON" and then turn the DESKTOP mode to "OFF" to see if the problem you mentioned will occur?

Don't worry about Q15 will come to brick after upgrade, it only appeared in the previous version of the machine, don't worry about it now!
Yes thanks, I can confirm that Phone Mode is switched to ON, and Desktop Mode is Off. I have consistently done this since the first day of having the Q15.

All sorted. Tweaked some settings as per Samsung(that'll teach me for playing about with the phone!) and then updated FW using @neobandog1 suggestion of opening new window to bypass security warning. Thanks to everyone who helped.

Edit - Daft question time. Does it matter which of the two supplied USB cables you use to play music back via the Q15? I find the small "decoding" cable a bit too small and therefore a bit restrictive. I'd much rather use the cable that is used for fast charging as it's less restrictive for movement.

I was listening to Q15 today and used the longer cable.

My assumption is that the shorter cable is for convenience of stacking the Q15 and a phone for on the go usage (so you don’t have a long cable flopping about).

Yeah that's what I thought as well but thought I'd check as the quick start guide does highlight what each cable is used for

Did you change between USB and BT when listening to the same song? There is a glitch that reactivates PEQ and thus applies a negative pre-amp value making the sound quieter.
This glitch is very real, don't forget to always cycle eq on, select a different eq preset, and then turn off. I do this every time before listening otherwise I'm left wondering why the sound quality got weird.

I can't open Fiios firnware link, the website just hangs loading for ages.. I recall a while back (years/months) Fiio had issues with their website (super slow requiring minutes just to load or not loading at all), seems they are still ongoing..

could someone already compare the soundstage depth and layering of the q15 with the questyle cma18? i would buy the latter, but it seems not to bypass the battery when connected via usb.

Not buy owned mojo 2, gryphone, ifi black label dsd and many more....q15 is in same league for me and better than mojo 2 for my taste
yeah your taste. we know you like your warm thick sound, so its a bit of a claim to call anything best tbh. best to your liking doesnt mean its technically the best.
