I play keyboards and if you play an instrument where you are not very mobile then using this as an in ear monitor is less expensive than a wireless system and very easy to implement

It almost destroyed my monitors and headphones which were plugged in.

Significant noise is present when monitoring via the phones jack; even when nothing is connected.

NEVER push the "To Main Mix" button when the USB is plugged in or it will create a loop back which will amplify all sounds exponentially and destroy your monitors or headphones !

Either way, I get a cleaner sound using my M-Audio M-Track 2-Channel Portable than using this turd

WON"T STAY
