Picture of USB Powered Speakers
You can use USB for everything! I have these speakers but I lost the adapter. I read some things about USB powering and I started to make an USB adapter for my speakers and it worked!

Step 1: Materials

Picture of Materials
- Speakers with a plug showed on the picture
- A pair of scissors, a knife or anything to strip the wire (even your naisl will work)
- Usb wire, doesn't matter what kind but it must have a male plug.
- Connecting brock.

Step 2: Preparing the wires

Picture of Preparing the wires
- Cut the a USB wire in half. (length doesn't matter, take the piece with the male plug on it)
- Strip off the isolation.
- Strip off some isolation the BLACK or BROWN and RED WIRES. On the photo you see which two i mean.
- Tape the 2 remaining wires to the big wire (See pic).

- Take off the adapter jack which is attached to the speaker set. (length doesn't matter)
- Strip off the isolation.
- Strip off the isloation from the two wires inside.

Step 3: Unite the wires and finishing

Picture of Unite the wires and finishing
- You can twist the black wire from the speaker set with the black or brown on from the usb cable and the same with the red ones...


- You can use a connection brick like I did shown in the picture.
- Take some black tape or something to make a clean finish around the connection.

Step 4: Enjoy the sound

You did it!

You may hear some noise coming out of the boxes, this is caused by the little power a USB port gives.

TIP: Out of USB ports?? Use a USB adapter! (See pic)

Your Youtube video is set to private and I cannot view it. This makes me wonder as your trying to get a analog signal from a digital interface. Isn't there a chip missing on the speaker side or am I missing something?

I changed my Youtube video specifications so you can see what I mean. The audio is not going through the USB port. Only the power to let the speaker set work. The audio jack from the the speaker set must be inserted in the headphones audio in.
