I have a Crystal UHD 7 series TV. We bought it because it was Bluetooth enabled and we thought we could use both our headphones at the same time. Unfortunately, we learned that it only supports one headset connection at a time. And if one person is using a headset--the regular speakers don't work. Do you have an recommendations for how we can allow for a second headphone or one headphone plus regular speakers? We need to be able to each control our own volume.
