Sometimes it depends on the CPU. Qualcomm and Mediatek should be fine. Maybe you can also try USB Audio Player Pro,  HibyMusic and Neutron Music Player, to see whether one of them works.
 
Otherwise it's because of your phone.

Thanks to Charles. I have something to play with during the holidays. Want to compare OPA1612, MUSES8820, MUSES02 and SS V5i.  Also try to improve my listening.

Can this power small bookshelf speakers and could i use it as a dac only?

Looking forward to your comparison.

Ditto, your op amp review will be very interesting.

Do you notice hissing when gain and volume set to max with nothing playing?

Just got mine, tried with my 650s and with my newly received Massdrop AKG 7xxx red. I am very impressed. My other amps are Schiit Valhalla 2, Asgard 2 and perreaux.

Do you feel like the hd650 is been driven nicely by it? Can you elaborate a little on the quality of the sound?

I kept the V5i installed in the XD-05 as you can see here. Such a great combination...

...no, there is no amp inside to power bookshelf speakers. It can be used as DAC only, but just via 3.5mm jack. As DAC I would prefer the ifi iDSD micro (which I am using myself for that purpose on my desk-rig) since it comes with RCA output.

Ok thanks musikaladin thats very helpful.

I was using the optical as a test I have been using it on its own for a while but I wanted to test optical and also I wanted to use my Beyerdynamic 250ohm which require a little more juice. 

So how's sq compared between the X10 and XD-05?

my opinion is based on about 20 mins of initial listening only. I did a little more today and it does drive the 650s well, even in low gain mode. The source is Roon on a Windows 10 machine. I listened to orchestral and vocal as well as electronic stuff. Sound quality is clean and transparent, although I think it lacks a little depth compared to Asgard 2 with the Valhalla 2,the whole groovy morphine experience is gone, but I would consider taking it on an extended trip away from home. I am waiting for an otg cable to test it out with my android phone.

Interesting that it can get a usable volume from 650s in low gain mode. I find that even with low resistance headphones, I seem to prefer the sound from mid-gain on this thing. The volume doesn't change much but the quality seems to change markedly for my SHP9500s and Status CB-1s, both of which are merely 32 Ohm.

Interesting comment, I have audio technica ad900s and found the same thing.
