Swapped out my cups for the 7keys wood cup.
Pretty easy mod. I did the hairdryer method to open the cups which took about 3-5 minutes for each cup before I was able to pry them open.
Then I used a combination of a hack saw blade and a dremel to cut into the inner shell and pliers to break away the shell. This part was much more difficult and I was constantly worrying about sawing into or damging the driver but it worked and didn't take too long.
Then it was just a matter of shoving the drivers into the wood cups which fit perfectly without requiring any glue or adhesive.
I used a mesh screen that I cut to size using wire clippers.
All in all a fairly simple mod
These things really do look quite beautiful. The grain on the wood is super interesting, and the tone of the wood is a lot paler than it appears in the picture. They are also a lot lighter than the plastic cups.
Now on the the sound:
Fantastic.
It really gives the music a much warmer, fuller feel and just makes everything seem more natural. The sound is much less plasticy.
I didn't hole punch mod prior so this also really increased the bass which is at a great level now.
The wood does a great job of taming the treble which was a tad too much before.
I can't put my finger on all of the qualities that makes them sound better but these just sound so good now.
Before I though these sounded pretty great, now they are probably my favorite headphones I've ever listened to.
Thanks again 7keys, you really did a tremendous job.
The rest of the cups are on their way to you Triton. Enjoy!
