As I understand it, the V-Moda headphones like the M80, LP2 and the M100 are semi-open instead of closed, so there's some isolation lost there in exchange for a better sound and more soundstage. I think that's what the vents on the ear cups are for.

Gear mentioned in this thread:
Fabric that covers the vents? Do you mean the fabric inside the earcups that sits over the grill that houses the drivers?
Not sure but I remember seeing some kind of cloth over the vent holes on the inside just beneath the shield. Never removed the shield to check. It looked like as it would have been attached to the shield itself.
Hmm... I have the V-80s and I swapped my shields for some custom ones. Didn't notice any fabric on mine. It was just the plastic earcup with the same 3 vents you see from outside the shield. I've never handled a LP/LP2 before, though.
Wait wait wait - Plastic?
The M-80 for sure. Val even said this a while back. Just makes logical sense. Bigger cups = less neck room.
They better sound amazing.
Well, imagine how heavy a full-sized, 50mm, circumaural headphone would be if it was entirely made out of metal. Bye-bye head/neck comfort. From my experiences with my V-80, it would take a lot to damage them beyond minor scuffs and scrapes. Heck, someone posted in the M-80 thread a while back that his mom ran over his M-80s with a CAR! Bent the metal arms all out of shape. Luckily, his dad works with metal and welded/soldered it back into wearable form and they still played just fine. Imagine that happening with any other headphone. (Beats Solo HDs, anyone?)
