So yeah; I think I found something that hasn't exactly been announced yet. Check out these officially-licensed Mega Man headphones by EMIO. They're styled after classic Mega Man's helmet and feature LED lights. Pretty spiffy, wouldn't you say?
You can pre-order these headphones right now for $99.99 USD with free shipping. Before you buy, do note EMIO did not provide audio specs. We don't know how good these actually are. They're certainly neat to look at, though. You'll find more images at the link!
Related-ish, EMIO also has Mega Man analog stick thumb grips.
