Works for me
Silent enough for live work.
O/I Button that’s it. 1 in 1 out
Ease of Use
Plug and play
The only gripe I have with this product is the 9 volt battery set up. The battery compartment has a foam block to keep battery firm in place. Battery wiring is awfully close to a sharp metal frame that may cut insulation. Battery connector feels like it will fail sooner, than later.
