A:AnswerYou can not directly connect a blueooth speaker to this TV or the TCL ROKU TV's unless it is a ROKU Bluetooth speaker which is proprietary BS by ROKU. However, you can connect your IOS or Android smart phone to the TV using the ROKU App and installing the ROKU app on your smart phone and sync the two up. You can then listen using your headphones connected to your smartphone. Going to check AMAZON FIRE Smart TV's before purcasing a ROKU Smart TV. ROKU may being losing a sale, I don't like proprietary BS, that's why I'm gonna kick DISH TV to the curb and for them dropping HBO with the last season of Game Of Thrones coming on in April. The world's most popular rated TV show. It might be possible to connect a $20 bluetooth transmiter with a 3.5mm stereo jack into the TV's headphone connection which is kind of ridiculous to have to buy with for a "smart TV", It's the age of buyer beware.
