Also wanted to give some, simple, impressions. After complaining a little about the seller on aliexpress not shipping them they have been here now for 2 weeks before I had time to listen to them, did some burn-in a few nights though. Compared them A/B with HD800S and the Ananda (v1 with see through mesh) from memory which I had like 3 years ago
Build / comfort: the radius of the headband fits quite good for me, not too much of a hotspot here. The strap of the Ananda did an even better job of course. What the XS shares with the Ananda is that they both are a little bit too big for my head. Iām on the lowest setting and could need like 2 or 3 clicks smaller, have to add some extra padding here. Not sure but I think the Ananda pads were softer, XS seems to be firmer. I donāt really notice the weight increase going from hd800 to XS. Not using the stock cable, only some cheap openheart aliexpress cable.

Bass: Even without EQ the bass on the XS is so much better. No sub bass roll of and the upper bass delivers a better punch and slam compared to the hd800. When I had the Ananda I mainly used them on a ifi xcan with xBass on all the time. Songs like run the jewels - oh Mama made a nice subwoofer feeling on the head without messing with the mids or make things muddy. Same experience with the XS and EQ xBass. Of course I can EQ the bass on the hd800 for more quantity but never get the quality of the planar bass.
Mids: the HD800S not being a mid range focused like the Hd6x0 (that I never liked though) I canāt agree with some experiences here that the XS sounds thin here. Vocals on the XS are not as recessed.
Highs: No surprise, XS is more laid back here. Was never really bothered by the 800s highs. Might EQ a little bit for more sparkle.
Soundstage / imaging: As expected here the XS falls a little bit behind. The Soundstage actually is not that much smaller. When I changed from my Ananda to the hd800 (not 800s) the difference seemed bigger. Imaging goes to the HD800S. On songs like wintergatan - marble machine or yosi horikawa bubbles / letter I can follow the objects moving around better.
Power consumption: the a30pro outputs 6W at 16 Ohm( high gain, pot almost at max). My Qudelix 5k is set to low gain (1V output instead of 2V ~ - 6dB) for a lower noise floor.
The sabaj preamp is at around -44dB when I listen at a louder, more fun volume. Together this would be - 50dB. Some (rounded, - 10dB = power devided by 10) calculation 6000mw/10/10/10/10/10=0.06 mW.
0.06mW (without EQ preamp) so rather easy to drive I would guess. Will try to run them just with the qudelix 5k when I get the time. When I was changing back and forth between hd800s and XS I didnāt had to adjust the volume. Pretty much on the same volume level.
I am not someone who has multiple main headphones for different use cases. Like I always want the comfortable headphone with good bass and an immersive headstage. So my plan was to sell either the hd800s or the XS. Given the price difference I think I will keep the XS and try to EQ for a little more open sound, adding some energy at 6khz like the 800 or so.
@ all who heard the hd800, Arya and maybe XS. How big of a step up would the Arya (V2) be? Especially in the stage and imaging category.
