Doesn't everyone have a box/drawer with old transformers?  Maybe it's just me...
 
Mine was from an old Sony portable CD player.  4.5v, 500mA.  Like this one:  http://ecx.images-amazon.com/images/I/518ZzXaOEAL.jpg
 
I had to pull off the plug from another transformer because the one on it was the wrong size.

I looked everywhere and couldn't find one... I'll look again, I'm sure I've got one somewhere. So assuming the headphones actually work, what should my next step be regarding the batteries?

If it doesn't work with a 3 volt transformer but it does with 4.5, then you need 3 batteries, not 2. If it works with a 3 volt transformer, then something is wrong with your 2 battery setup

Still digging through drawers and boxes! I'm going to pull the other side and see if there is something wrong over there.
 
Thanks for the help.

hey guys. this thread has been a lot of help, i recently picked up a pair of beats headphones with a ripped cord for a good price thinking i could fix them, come to find out that they are a demo version! i have here a green cord, a red cord. which were braided incopper. and i have a black cord and a blue cord which were also braided in blue and copper wire. im stumped on how i can get thesse to work. i was guna hack it to a bluetootch speacker and use the recharable battery to that to power them. but if i must ill us a transformer to power them. i jsut dont know what cord is which and what voltage i need. im assuming the black and blue cord are power + and black being - and the red and blue cords being l and right speaker with the loose copper as ground, but so far i have had no luck, any suggestuons would be much appreciated thank you!

maybe i can explain it better. when spliced there are two chords. both wrapped in copper. one wrapperd in plan copper the other wrapped in a blue stripped copper. the chord wrapped in stripped blue copper have two chords., one black and one blue, both insulated. the other chord wrapped in plan copper have two chords also. one green and one red, both insulated in clear insulation but they are colored wire. i picked up today a 1/8" stereo plug where there is room for 3 wires. ground. left speaker and right speaker. considering studios requaire an outsidde power source im going to some how have to power them, my question is which wire is for the left speaker, right speaker, ground, power and ground. if i could post pictures i would. once again any help would be aprreciated as im very excited to get thesse headphones working properly! thank you!

okay so i connected the red and green wire to the new headphone jack. and the copper wiring to whats supposed to be the ground for the headphone jack. the blue and black insulate wires arnt connected. but from what i read i should be getting some sound but not at full power. i sanded the color wires so it has some connection, but i get nothing. im stumped.

That circuit looks rather unfamiliar to me. What is it from again?

 

[xGuso]

the circuit is from a bluetooth speaker. i can get an ordinary pair of headphones to run off of it. but i cant get the beats to work for the life of me, with or without bluetooth. im using a 5v 800MAH  dc adapter.

I was given a pair of demo 2.0 studio beats today what is the correct power supply

 

[cypherciti]

And can i convert to usb charge or battery

I think you'd have to rewire the Beats from the scratch if you want to get it to work with Bluetooth. That's what I did with the original Studios.

The demos weren't made with rechargeable batteries in them, I don't think.
