Honestly if you hear 8331 you will forget headphones.
The 8331 is more detailed than headphones. You might wonder why. The reason is space. Instruments just hang out in front of you. You hear everything in its own space. You notice things which the headphones cannot show you in the limited space between your ears. Instruments get smashed up together.
I do not have a dedicated room. Instead, I put lots and lots of thick, heavy absorbers and a carpet in my 24m2 sleep+living+office room. Spent around 2 or 3 grand.
Given that the only space I could use them is on my digital Piano since I use 2 screens and a big tower PC on my table, its different. I would be able to toe them in and having slightly more distance.I have never tried $4000 headphones but I have tried $1200 ones. Nothing too special. Also a friend of mine tried his brother’s Orpheus. I did not get one word about how they sound. That tells me enough of what I need to know. Of course this is an opinion thing. I cannot imagine a music lover sitting in front of any Genelec ones and not have something to say about them.
Also headphones are uncomfortable in their own right. This thing on your head plus the heat and the ear pain. This is why for headphone I just get Bose. Blasphemous I know but comfort matters. No point hurting while listening.
The heat is a real issue. But the pain... I dont have that on my Beyerdynamic DT 770 / DT 990 Pro
They do not support proper AUX and I doubt they will beat the Tannoy's because sound over Bluetooth is worse. At least thats from what my testing showed.One thing that you can try in the meantime is to toe out the 8010 and live with the limited output but sit further from them. I know they sound so good you want to strap them to your ears but they won’t sum properly but you can aim from a consistent axis. If they are stationary to your ears you won’t have limited sweet spot it will move with your head turning. But your head won’t bear that weight.
If you toe them out maybe you will get less highs but your sweet spot will be more forgiving.
Not exactly toe “out” but maybe toed in less than pointing them at your ears.
So I have 8341 now and this balance between a tight but very sweet sweet spot and a more forgiving but not as sweet sweet spot still exists with them.
Right now they are pointing at my nose. The correct spot is so sweet. In fact it’s kind of obvious so you will naturally fix your head to that spot. Still turning the head is fine just left to right position matters a lot.
The alternative is to have a wider sweet spot but center vocals are not so razor focused. Finding an obvious perfect position is much harder but it’s decent for a few inches left and right. Maybe even 6” and then the center moves with your head. But the quality of that center is lower when you finally move that far.
In the more focused set up the center moves very fast and then collapses with side to side movements and the quality decreases rapidly.
It’s also interesting that in my experience many systems are forgiving of turning the head in terms of center image position but tonality declines rapidly.
Actually a pair of Apple HomePods is more forgiving about turns and side to side was forgiving. Maybe its wide dispersion?
My room is treated as far as possible. Every glass surface is covered with heavy acoustic elements. Every corner has 2 basstraps, going to the ceiling. In the middle of the room there is one big ceiling absorber. Although lightweight because my ceiling is not able to hold so much weight as it is a in-between ceiling and the actual load-bearing elements are after that.To hear voice in recordings some room treatment is a must. With small setup you may need only 2 panels on the ceiling and maybe one or 2 behind/around each monitor.
