Hi,
I got it to work, but if you have the volume right up it would cut out and said it exceeded the power limit.  I think you need a usb hub in between to get around this.  I am hoping that the new L19 FiiO cable may fix this whenever it finally comes out.

I finally got the K1 to work well with the Nexus 5X and Marshmallow.  All I needed was this OTG cable:

No dropouts.  No power problems.  Occasionally, I have to plug it in twice.  Works well with Spotify, which was my end goal.

Hi could anybody help me decide this question - fiio x1 vs smartphone + k1? I'm mostly interested in sound quality as things like battery life or comfort are not my priorities thanks

The K1 don't work with all kind of smartphones - so the question is what smartphone do you own? If you look in this thread some report to work and others doesn't and this problem is not a driver issue which is easy to fix with apps like UAPP, HibyMusic or Onkyo HF player, the Android version like 4.4.x or 5.x doesn't matter too.

Few examples:

Samsung Galaxy Note 4 (4.4.2), Samsung Galaxy S4 (5.1.1) and Sony Xperia Z1 compact (4.4.4 or 5.1.1) don't work. HTC One M9 and iPhone 6s Plus working with K1.

Sound wise the K1 has less hiss as the X1. Power output slightly higher on X1. Output impedance is better on K1, which is for sensitive multi driver IEMs important. SQ equals for both and you need to admit that the X1 is a dedicated DAP and the K1 is "only" as USB DAC/AMP and needs a working source - so choose what you prefer.

I didn't have luck with Galaxy Note 4 (5.0.1) and Galaxy S5 (5.0.1) either.

Do you know if the K1 works with a Samsung S6 ( 5.1.1 ) ? it doesn't my priority but i'd like it

Thanks a lot for clearing things out Fiio said that K1 should be compatible with galaxy note 2 that has similar sound setup as my galaxy s3, so I will give it a try. 
 
One more question - has anybody tried K1 while playing PC games?

I own a Nexus 6P and XB90EX, is K1 suitable for a basshead like myself?
 
Right now, I'm managing the audio by ramping up the gain which has it's flaws but I am open to suggestions.

Has anyone compared this to the Schiit Fulla?

Bassheads should be looking into headphones with enhanced low end response and also tweak the EQ to go beyond that

  You want your source to be close to flat, not colored or saturated at any frequency.  Or as an alternative, get a model with hardware Bass Boost switch, like FiiO's Q1.

I've already got the first parti (XB90EX is a Bass Boosted IEM). I am not sure without tweaking the EQ(powerAMP), I wouldn't have been much satisfied.

Under $40 (for K1) and considering you have Nexus 6P (which should be supported, usb otg) and Basshead IEM - you are all set!

Thanks, dude!

I suspect most android phones will work when you upgrade to marshmallow...  The USB Audio support is default... Previously phone creators tweaked and implemented it themselves.
