I couldnt listen to most jazz on these headphone,so I decided to trying and tame the bass just a little. I added a bit of form and a piece of shelf lining.

Better. I can listen to most jazz now. If you dont like the sound,you can undo the mods.

With a finger. Push and lift at same time. There are 3 screws holding the baffle.

Thanks so much for the info! I've been curious about this, just haven't had time to screw around with these, let alone really audition these since they arrived.
Coming from bass light 701's these are a bit brash at first, yet very fun and involving. Taming the bass, even a notch, would be grand.

How did you remove the felt ring? Is the ring 'glued' on?

If I don't like the sound signature of it after peeling it off, is it still possible to put the felt ring back?

There are 2 layers of the felt. I would recommend taking off only the top layer (peels right off) because the bottom layer helps keep hair and dirt out of the driver. Taking the felt off is hard to undo, but it shouldn't change the sound signature so much that you will suddenly hate it. Only a slight improvement in mids imo.

I see. Sounds like good news to me.

When you say 'improvement' in mids, I assume the mids would be more forward and clearer after having removed the first layer of felt ring?

(Just to be sure before I mod it)

The biggest improvement in sound on these comes from a week of burn in. Removing half the felt helps a bit. And EQing does wonders for these as well, as they're a bit weak in the mids, but just a bit of EQ really brings them out.
