I dont know the voltage of the battery, it doesnt say anywhere and i cant find the full specs anywhere on the net. Ill take pictures tomorrow.
What do you mean long time effects? i understand the battery will drain quicker, but i have great battery life already and the battery that was originally in the adapter was only very small and lasted 8 hours, so they dont use much power.
I have plenty of room if i remove the blue padding and cut a few things off the adaptor.. i have to cut the charger plug off meaning theres no going back:P
heres a link to the headphones in question:
