Officially official
If Mega Manmerch can be made, Capcom will either make it, or allow someone else to make it. It’s the eleventh commandment. Look it up. The next piece of merch on the block is the official Mega Man headset, complete with LED lights from EMIO. They’ll run you $99.99, but the audio specs are not public.
I’m dubious as to the quality of these, since you can get some rockin’Sennheisers for under $100, but the novelty factor is obvious.
