How to identify power required by speakers? Answered

I'm trying to adapt a pair of headphones to a bluetooth module for a wireless headset. I'm using a common module found here. http://www.ebay.com/itm/311523753533?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT 

Spec sheet says "Stereo audio output can directly drive 40mW @ 32Ωspeeker without the need for DC-blocking capacitor"

I have some old sony headphones with a microphone i would love to use but i cant identify how many watts and or ohms the speakers will need. I wont need the microphone, but if i can get it working it would be cool too.

I've identified the headphones model as PSP-270X but i cant find a spec sheet that includes the type of speakers included.
So i took apart the headphones but the only markings they have on the speakers are ATZ2261, And a couple google searches came up empty.

Is there a way i could test these headphones?

Go to a store find a comparable set of headphones look at the specks on the back of the package.

Direct on-ear headphones need only mW to drive them. More important is to find out what impedance the headphones are.

Do you know how i could find that information? or how i could relate that to the maximum 40mW @ 32Ω?
