Unable to listen with two pairs of headphones on Apple TV
I have an Apple TV 4K with Wi-Fi + Ethernet, Two sets of Beats Studio Pro wireless headphones. The apple support page Listen together with two pairs of headphones on Apple TV - Apple Support
indicated that is possible to listen to both sets of headphones on the same show or music at the same time.
The instructions regarding the control panel were entirely available on my set. I spent a considerable amount of time on the phone with apple support and their conclusion was that it is impossible to listen to more than one bluetooth headset at a time regardless of brand or make. They would not acknowledge the information on their support page.
