Dear Head-Fi users,

I recently acquired a pair of Sennheiser HD 212 Pro's.
Upon changing the damaged Ear pads, I decided to open them up and see what's inside. (Also it was a bit tricky to change the pads, not much room to get in behind)

As I'm new to Headphones and Audio, I am wanting to inquire as to what "soft mods" I can perform on these to achieve better sound quality.
By "soft mod", I mean a modification that is relatively simple, or can easily be reversed. (E.g. Adding dampening material, not cable changes)

I'm looking for more bass and softer mids, treble is fine.
Most people say these have tonnes of bass, but I found it to be lackluster no matter what I drove them with.
Treble meanwhile was quite nice and defined, mids were a tad harsh.

So, what are my options in modifying them?
I have attached some pictures so you can see what you're dealing with.
So far I have seen no pictures on the internet of the HD 212 Pro's drivers or "insides", so I took my own.



Any and all useful information is appreciated.
If you would like/need any more pictures simply ask and I will upload them.

Thank you for your time and support.

Does no one know of a way to mod the cavity or rear of the driver to increase the sound quality and smoothness of the Bass and Mid-Range?

Just after general advice, nothing too specific.

Seriously, 40 views and no input?

This is Head-Fi, the place where Audiophiles to share knowledge and advice:
Does no one have either to offer inn this thread?

Eagerly awaiting input, I just want to improve the sound ASAP.
I'm experimenting on my own, by some experience would be greatly appreciated.
