Another opinion:
Not all rooms are the same.


1-The Mic. import in the Bose sounds for good voice.
2-The second does not give you control of bass and treble.

Using a mixer:
One channel for voice and one for the keyboard.
1-Voice channel --- you control Bass, treble, some have mid-range, volume, and reverb. Bose also has Bass and treble for the voice, but the mixer is in reach.
2-Instrument channel --- Has Bass and treble.
Voice channel Pan to the left Instrument channel to the right.
Now you are prepared for whatever. I bought a small quality mixer.
Why not?
