Is there a expensive air decompression system

[verticallimit]

Can companies order a cheep or a better and more expensive air decompression system in commercial aircraft, for example, Airbus / Boeing
I ask because sometimes I experience more pressure for the ears in decent.
The list is long of extra purchases when buying new aircraft, there are many options, but is there a grade of the pressurization system.

Or is "hard" decompression controlled by company rules, pilot related or even manufacture related.

Thanks.
