I read an Amazon review which influenced me a lot and I have decided to use the brainwavz velour pads. I do not know even if I changed them properly or even if this leather enclosure can fit inside the space as the original one.
The way I am using them right now obviously make the headphone look a lot more uglier although so much supremely comfortable to me since I love the velour feeling. To be honest though these velour pads are not even close qualitywise to the sennheisers 6XX series pads which I really adore.
The diameter from the inside part of the pad is smaller I believe and this probably affects the sound considerably.
Now YMMV a lot and maybe you will NOT like the change in signature and that is quite understandable.
But if you like the change it is very probable that you will like it a lot since according to me there is a significant change in the sound signature. To my ears this is a game changer not a fine tuning move.
These pads + balanced cable + xCan = I do not believe what I am hearing.
Only thing I need somehow to place them differently and make the headphone look pretty again.
I hope Meze will devote effort to really develop proper velour pads of serious quality for the 99 series.
