I had that same Yamaha headset mic. It's designed for computer connection, but includes a separate battery/preamp box that you need to use to convert to a normal 1/8" or 1/4" output. I used it a couple times for a jam/rehearsal (with one side off-the-ear so i could still hear) and found that the mic wasn't very good. Tossed it in the trash when the foam earpieces started to disintegrate.
OK, that being said - i'd kicked around the idea of trying a headset mic again, based on the experience of Gary and others on this board. Picked up a (relatively) inexpensive Shure PGA31 condenser mic, figuring i wouldn't be out much if it didn't work out. Note that headset mics in general are designed for connection to a wireless transmitter, so you need a preamp/adapter dongle (which costs a bit) - Shure sells one but i'm having good results with the cheaper YPA A65P. And you will need phantom power, so i'm not sure if your keyboard supplies that.
Bottom line - for me, the advantages of going with the headset mic far outweigh the disadvantages. I love not being stuck in one position behind the keyboard - i don't have anything between me and the keyboard, i'm free to turn toward whoever i'm singing to, and can even stand up when i play a song on flute (the headset mic picks that up just fine). And not having to deal with a mic stand is one less thing to worry about forgetting to pack.
Oh, and that PGA31 condenser mic has way exceeded my expectations, no problem with the sound at all.
Just my own experience,
