Hi! I just can’t decide what will be best for me. I have simple IEM HiFiMan RE400. Also iPhone that I could use with Q5S.
Shanling M5s pretty much fresh player, but I can’t find comparison with X5 III.
In the future thinking about Sennheiser HD 600. So need something that will be best with RE400 and HD600.

I've got the Q5s and I'm a fan. It has a pretty clean sound signature and the bluetooth is a nice touch. I'm not so much a fan of its design (it would have been nice if FiiO emulated the FiiO Q1mii or Q3 design), but that's a small point. Might worth checking XDuuo's XD-05 (there's a basic and plus model) - they have a bluetooth module that you can attach to it for about $60. The plus version is going to yield more than enough power for full-sized headphones. If I remember correctly, the basic model yields about the same output as the Q5s balanced, don't quote me on that though!
