Solitude XCS2, Active Noise Canceling Headphones

I see nothing in your description about battery size, type and how long the headphone last on the battery. I am also hoping it is a replaceable regular battery like AA, AAA or button cell, not one of this use them up through away fixed type rechargeable. I work hard for my income and want headphones with batteries that will last. these sound nice, as usual, Amazon drops the ball on the description. What are the battery specs Please.

From Amazon they need 2 x AAA
