Hello,

To adjust the volume individually on two sets of headphones connected to your Samsung Smart TV and Sonos soundbar, you’ll need to check if your TV supports dual audio output and independent volume control for Bluetooth devices. Some Samsung TVs allow you to connect multiple Bluetooth headphones and control their volume separately. However, this feature may not be available on all models, and it’s often limited to compatible Samsung headphones.

For non-Samsung headphones like your Ace headphones, you might only be able to control the volume directly from the headphones themselves, not through the TV. If your headphones have their own volume controls, each person can adjust the volume to their preference directly on the headphones.

Not according to the current threads. Only one set of headphones can bond with an ARC and ‘switch’ from ARC to headphone listening.
