I've been trying to find good headphones for a while and found some nice looking ones, however I cannot for the life of me figure out what a microphone sensitivity of -113 dB listed on the site means, google is of no help.

Probably a bogus number. That's way beyond anything anybody could ever hear.

i believe sensitivity is the volume it can reach with a milliwatt of power. 113db sensitivity means you can reach 113 decibels with 1 milliwatt or power.

That would apply to headphone sensitivity. OP twice mentions microphone sensitivity which is typically expressed in dbV. A -113dbV rated mic would produce 113db less than reference, often 1V. If another analog mic is rated -103dbV sensitivity it would produce more voltage (be louder) than the one OP is looking at.
