Hi this is my first thread so please be gentle I have just bought a set of Blackbox i10 iPod/iPhone Noise cancelling Earphones any way they use the ipod 30 pin dock plug for power hence i will be unable to use them with my MBP. So i was thinking could i splice a usb cord open and use its 5v to power the headphones and use the MPB audio jack for sound. Obviously i would need a female dock plug to connect to the headphones. then it would just be a matter of soldering the usb from the MBP to the power pins and run a cord from the MBP audio to the Audio pins on the 30 pin plug. I hope that makes sense So the question is would this work? were would i get a 30 pin plug? Is 5v to much power?
