Wow, an accessory mesh! =o
Anyway, I've also hated the only headphone mesh on IMVU, and have been dying to make my own mesh. I decided I'd also add some sci-fi looking things onto it, too. Anyway, this mesh is REALLY customizable- the only things that DON'T have opacity maps are the bits that go over your ear. Everything else does, meaning developers can make pairs of headphones in quite a few different styles! ^^
Mesh Features:
-2 different headphone band styles! (over the head and behind the head)
-Sci-Fi Visor! Can be customized via use of opacity map Template Here!
-Cool Sci-fi tech ear-wings/antennae! It'll go well with any sci-fi themed avatar!
-Inner Earphone Template: Here!

Thanks for looking! Any questions should be directed to my homepage, I check it daily! ^^
UPDATE! The mesh clips one of your avatar's ears a bit, I will be looking into this!
