DON'T BUY if you only want to use the TV's internal APP with your arc soundbar. We suggest using an external player, for example, Apple TV, for the best atmos effect in your earc soundbar. If you experience sound cut issues, please turn off TV CEC or change your TV HDMI port to a non-CEC HDMI port. No eARC TV? No problem! And no more lip sync issues for eARC TV owners! WORLDS FIRST eARC adapter allows FULL AUDIO up to Atmos over TrueHD from ANY external HDMI source to ANY eARC sound system. It's the perfect solution for any eARC AVR, soundbar, or headphones.
