Just received these after much research including speaking to Avantree customer service. I had questions and they were willing to give me a replay both via chat and email. That's all I wanted to make my viewing experience more comfortable. I can connect the included headphones in addition to the Bose headphones for my partner who wears hearing aids. Also, I have TV sound, so if more than two people are watching, everyone can hear the TV. My TV is a new LG Smart 8600 TV with native Bluetooth, but it was useless to plug in more than one headphone at a time or output the TV audio when connected via Bluetooth. That's why I bought Avantree. Easy hookup and a two-year extended warranty when you register your product on the Avantree website. The sound is very good, no delays. The volume control is easy to use and responsive. I like the voice prompt telling you you're connected, but I understand it can be turned off. They should work with most TVs as there are many different cables listed in the product description.
