This is such a great gadget on stage! A stereo monitor mix is not a commen thing these days. You could choose between your own sound and the mix from the table, to get a great balance. The sound is good, not that loud, but good earbuds will do the job. The batteries die very quick though, I advise to use an adapter.
For the price, its an awesome gadget. Way cheaper then wireless systems, but youre more limited in movement.
