Most definitely has Bluetooth, and wifi. I connect my audio receiver (via Bluetooth) and my Vizio soundbar to it. Virtually no lag in sound. This is an awesome Tv with an awesome picture. (the depth is amazing) HDR is questionable though. The new standard is HDR10 and this series is HDR8, as in 8 bit vs.10 bit. To be honest I don't know how well it works compared to the 10 bit (as I don't have a 10 bit hdr tv) but I do have and have had several 1080 screens ,Elements, Vizio, HP, and this pictures is soooo much better. Plus it automatically updates itself (if you let it) and the super simple remote (5 buttons and the circle in the middle) controls my xbox, chromecast, soundbar, firestick and more!
