A:AnswerThe ENERGY STAR® Qualified LG 4K UHD HDR Smart LED TV - 49" Class (48.5" Diag), Model # 49UH6100 does not have a 3.5 mm (Headphone jack) port on it for connecting wired headphones and it does not support Bluetooth so you cannot pair Bluetooth Headphones to it either. It does have an Optical Digital Audio Port on it that you might be able to use depending on what type of headphones you have but you will also need to get a Digital/Analog converter with RCA outputs and an Optical Digital Audio Input at the other end to make it work for a specific type of wireless headphone...^IFV
