Noise cancelling Earphone Hacking

[wrignj08]

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?

What about this?

"CableJive Universal Dock Converter"

But with a male usb, could some one advise me if the ipod uses the same pins to charge as it does to power other things such as my headphones or an iTrip.

Could i just get the converter a male to male usb cord and a male to male 3.5 audio jack and b set? i think that sounds to simple.

So it is looking like the ipod puts out 3.3v to charge things so i will need some way of stepping down the voltage from 5v (usb) to the ipods 3.3v. Any simple ways?

So just found out that the SD card slot on my MBP runs at 2.7-3.6, any way of patching a cable to a SD card to steal its power and send it to the headphones?

Ok so this is what i am thinking if i get a "SD CARD READER EXTEND CABLE" splice it up and find the power cords run them to a female ipod dock to supply power (the other end of the SD cable will be in my computer). Then run a separate cord that runs from the computers 3.5 audio jack also to the female dock and hay presto mission complete!!!!!

Will this work????
