Uses: TV with August EP 650, an Aux input on a Prius II with a Nexus 5 and in my room on a PortaPro Koss. All this works perfectly, no noticeable latency with TV, just cut-out when the level is very low (DECT type). In the car it sends a max. Good material, so good, I am satisfied.
Edit:
Now I use a Sennheiser MM 550-X on the Saturn Pro is perfect for the Home Cinema night and more than "cut-out".
