Thanks Joe for the Hiby Music update apk....updated to version 1.6.6 and seems to be working well for me.

Mine came with two screen protectors on the front screen - the really obvious one, which I took off straight away and came off easily, and then a second one underneath that I didn't realise was on there until a couple of months later. This was more difficult to take off and left some residue on...

Excellent stuff, thanks for this - I love fiddling about with settings. On the same subject, is there any plan for any type of reverb plugin in the future? I continue to be amazed at the sound that comes out of this little device.

Just been playing around with the system wide MSEB, an excellent development. Had been trying various players over the last couple of weeks and couldn't get Michael Jackson's voice to sound as good as with Hiby's app with MSEB active. For example the Jet Audio app has something called...

For anyone in the UK, the Fiio K5 Pro is now available for pre-order on advancedmp3players.co.uk for £149.99. No due date for stock that I could see though.

I upgraded to an 8-core Fiio LC-3.5C cable for use with my FA1. No change to the sound that I could hear, if there was it was subtle. Nice cable though, thicker and easier to untangle than the stock cable.

Looks good - all in one DAC/AMP with three level gain on the front plate, not too many of those around. Will sell well, thanks for the chance to win.

thanks sinquito, yes, that would make sense. It's not a huge difference but it's there if you look for it, with higher quality recordings anyway.

Been using the NX4DSD as a desktop dac/amp plugged into my 2010 iMac, servicing a pair Sennheiser HD599s. Had my eye open for a bigger desktop amp (which I may get still just for a bigger volume knob), but with the HD599 this combo is more than enough for me. The gain switch is useful on some...

Thanks Brooko, I'll hold off for now and and enjoy them as they are. I'm sure I will contract 'customisation fever' at some point though!

Like Giambuca a few posts back, initially I found the FA1 sound flat and I thought there might be a fault with them, but they were my first IEMs and didn't know what to expect. I was also listening to songs that may not have been the best at showcasing the FA1s abilities. Swapping over to...

Hello to All, Headphone user over many years, now using a new pair of Fiio IEMs and getting into the science of it all, EQing etc. IEM sound quality seems to have improved since my last pair a few years ago! Cheers
