A:Answer Currently, our TVs do not support Bluetooth. If you are trying to connect a sound bar or speakers you can use the Optical port, or the HDMI ARC port. For Headphones, there is a Headphone jack on the back of the TV, or you can download the Free Roku app for private listening. Additionally, this TV has the ability to connect to the Internet via WiFi or Ethernet. It supports both 2.4 and 5GHz WiFi. Hope this helps! Thank you, TCL Customer Support
