Yes and no. You can use two headsets at the same time on one Xbox but ONLY if you are signed into TWO separate Xbox Live accounts. If you only have one Xbox live account and sign the other player in as a "guest" it will not work.

Unless the karaoke machine has the connection the same as a Xbox 360 controller, then it might work. However, the connection for an Xbox 360 controller is significantly smaller than a regular headset (think Iphone headset). I would look at the connection before determining if this product is right for you! Hope this helps!

I don't know what other devices this works on, but there are 3 plugs. The usual headphone jack that you plug in, and 2 side ones. Did that makes sense?
