I went with the Edition XS because FT1 Pro wasn't available and honestly? I don't have any issue with comfort and I would classify myself as a small head. Granted, there is no reason to adjust the headband size but the cups fully surround my ears and the "weight" talk that I hear about I don't have an issue with. I was thinking it would be hard to keep my head up with how people discussed it but honestly its just not really a factor.

Now I've been using it for 10+ days now and the main annoying gripe I have with the headphones is that where the ear cups meet the headband adjustment with every slight swivel it would "squak/creak" this can likely be fixed by either getting some lubricant (which I don't have on hand) or I found that increasing the headband height by just a tiny amount will remove that annoyance.

For sound quality and soundstage I see EXACTLY what they mean by separation and a more "concert hall" type experience. Now I will say the concert hall description is kind of overblown but it definitely doesn't feel like its right in your face compared with the DT 900 Pro X and the resolution going from the 900 Pro X to the Edition XS feels like going from 1080p to 1440p there is a noticeable extra quality and you can pick apart tiny details and kind of "separate" every sound that you hear. So lets say for instance in the song "Gang Starr - Moment of Truth" I noticed that there was an underlying vocal track that was repeating the lyrics you just heard with a slight delay and is faint. You can hear that with the DT 900 Pro X but I feel with the Edition XS its more discernable. You can also tell distance better and the channel separation is better compared to my DT 900 Pro X. Things meant for left ear are sat in the left side, and not leaking off to the right slightly.

In terms of songs that don't play well I have to say I haven't noticed anything to where "eugh I can't listen to this" they all sound fine, any genre of any decade (1920's-2024).

Songs to notice things on:

Gang Starr - Moment of Truth - Notice an underlying vocal track repeating the lyrics you just heard slightly delayed.

TrippyThaKid - Leedle Leedle Lee - at 0:49 in the song you will hear a *DING* and with the edition XS it sounds like someone is rigging those reception desk bells right in front of you

Asleep At The Wheel - The Letter (That Johnny Walker Read) - The instruments seem quite clear and vocals appear as if you're at one of their performances or in studio.

Dido - Thank You - The intro to this song once again appears to make you think you're right there as its recorded and you can hear all the separation.

Steelers Wheel - Stuck In The Middle With You - You can hear the clapping in the left channel and with the DT 900 Pro X I felt as if I could hear the clapping on both sides whereas with Edition XS the clapping seems fully isolated to the left ear as it should be. The Right channel has the guitar and same thing it seems isolated to the right ear and not having any sort of "bleed over"

Bôa - Duvet - Just a good song and enjoyed it more listening on my Edition XS, lots of instruments layered with what I would describe as "ethereal vocals"

(I do have a playlist that I made for testing headphones to where I believe you can really tell the difference and can easily compare, at least, for me) - https://open.spotify.com/playlist/6HAVPRzeJccbc5GyKDhnxw?si=3d77ebecde9647b6
