Title: Crack with wireless headphones
Post by: Deluk on January 12, 2016, 01:17:01 AM: Not started my Crack build yet, I have HD600. Being as all of the wireless headphones I've researched seem to be 32 ohm, what is the impedance that the Crack actually sees? If the transmitter is rigged to be plugged into the headphone socket will the impedance of the transmitter also be 32ohm? If that is the case I would guess that no wireless headphone will be compatible. Anyone tried it?

For wireless, the "transmitter" takes a line level signal, sends it to the headphones using some form of wireless transmission and then amplifiers in the headphones take over. What would the Crack be doing?
