So I was looking around for a setup that would allow a hookup, where I could connect to the mic in, and the headphone jack out with an "all in one" headset/mic.

I have found the Yamaha CM500 Headset Mic on Amazon that has two 1/8" cable jacks, and i assume one cable connects to mic in and the other to the headphones out. Not sure if this will work on the SX900, or any other keyboard for that matter. Anyone use this particular headset, or have a similar set up with a recommendation?

Thanks
