if you mean room treatment, most people just don’t have the ideal room layout / space for to properly incorporate not only broadband absorption and bass trapping— but diffusion AND soundproofing.
For a “proper” listening space, they all need to be in harmony.
For a listening space being built for the ground up, they all need to be taken into consideration.
I made some simple broadband absorption panels and bass traps myself. But I can’t do clouds or diffusion. And was only able to add traps to my front corners. My listening area is small, a 10’x13’x8’. With a ~3x5x8 opening in the room as a closet space. But I like to think it’s better than most.

But a lot of us deal with what we have. Not having an idea ll room shape, squeezing speakers into rooms that are WAY too small for them, adding too much broadband absorption with not enough bass traps, wanting to add diffusion where it won’t be utilized as intended because of space constraints etc.
sadly, not enough people give a shit about room treatment and it’s a shame because it gives incredible benifits. Too many people start going down the snake oil path and buying gear that— measured on scientific gear is noticeable… but isn’t audible.
Not only that premade solutions are expensive. For a small listening space that can incorporate absorption, diffusion, and bass trapping it can easily be in the ~$1,500 range. And that’s not something that can easily be a/b tested.
Dude learns his country is small and shipping is expensive lol.
I’ve never had a problem with returning stuff from drop. Drops where I learned about how bad hifimans stuff are lol. I had to return 3 headphones multiple times. All with noticeable defects. They never gave me a hard time.
