Spoiler: The 3D audio is really uneventful if you have been used to any kind of surround sound system, especially Dolby Atmos one.
I can finally answer You since I've had the headset for about an hour now and post my little early impressions... only 3d I've used on pc previously was the dolby headphones etc few years ago. All distorted sound too much.
Holy fucking shit does Demons Souls sound amazing.
I've only ran it on default middle(3) level in ps5 settings and it sounds so immersive I am astonished !
All the little details in environment and the thump when you parry ?! nice
No hissing, static or anything wrong as of yet.
The comfort is somehow spot on. I am not a fan of over ear headhpones but these are very light and do not clamp too much at all but comfort can't be judged after barely over an hour.
Maybe the top rubber thingy will be a problem after few hours. I can see that. Not a huge fan of suspended headphones but these are ok now.
The earpads are made of low density foam it seems as they do not block too much outside noise and so far my ears can breathe just right.
I've had experience with Brainwavz hm5, takstar pro82 and both of these super soft italian sofa pads are so soft and crate such a seal that I can always hear my heartbeat, a cable and it's too hot.
The foam is of cheaper kind in pulse 3d but it does not seem to create the hot death seal or hotspots. Of course nothing is as summer friendly as porta pro.
I've also played Maiden demo and not sure if I should enable 3d audio in the game options on top of ps5 system 3d. I guess so since I think it sounds better but did not had enough time yet.
Now I am listening to music on pc. It works flawlessly too. The windows volume does nothing and all volume is headset controlled.
No volume issues on ps5 or pc. I run it 2 click below max so far.
The audio quality is great honestly. Some people said it lacks bass? not at all. it is exactly where it needs to be. Punchy and all.
The headset sounds wide and spacious. I love the bassy sound of Porta Pro and these are a bit more detailed maybe with bass going lower but also not spreading... no idea how to describe sound.
Overall so far? Impressed with 3d, with sound and comfort. I've not had super high experience but I do use Koss Porta pro and fiio e10k daily. Used more expensive headphones too but Koss always sounded most open and fun.
edit: No way to check battery level on pc right ?
edit2: These smell great lol
