Very nice, high quality build, does what it’s supposed to do
Right out of the box this unit failed. I tried different cables and I only get audio from my headphones right ear piece. I know it's not my gear because I use my phones all the time in other equipment. I tried using both 1/4 and 1/8 plugs too. Also, the music that does come from the right earpiece is a dead, flat, powerless sound. No joy. Returning.
