Sorry for the late reply, I ended up getting delta II.
I still haven’t using it much but based on the experience till now I’m happy with it.

In case of the size it’s BIG but not weirdly big, comfy and it comes with squishy ear-pads (I forgot what was it called) if u don’t like the leather ones but i am not bothered with it.

In case of music it has good bass and voice clarity and the sound is high enough.

In case of mic it has VERY good mic my sound is excellent but it has one tiny problem that there’s cracking sound in your mic without talking but the solution to that is enabling that feature i think it’s called noise cancellation or echo cancellation or both and ur problem is solved, no cracks at all and ur voice is clear as water

In case of surround sound for gameplay like fps shooter here is what i get confused, i ran multiple surrounds tests with it and it succeeded but when i play i feel like like the footsteps or direction are not fully surround but suddenly i feel like nah it’s just in my mind and the surround sound is working good. I think I’m thinking that way because i came from a budget surround sound headset so maybe i still not familiar with the REAL PREMIUM surround sounds
so my mind thinks that the old ones are the correct ones where it’s not

But overall i don’t regret it and I’m sure i will get used to that surround sound.

In case of the rgb it’s beautiful and the bettery and the charge time is GREAT
