A:AnswerJust like cell phones or any other modern technology nowadays. Hardware has been improved in upper/newer "series". There's slightly better improved between the 6 to the 7 series Samsung. There really no major improvement depending on how well your eyes can see. The 6 series and basically your entry level. The 7 series will have a little better processor and better range in color. Hope this helps.
A:AnswerYes, you can connect a Bluetooth adapter to the yellow audio output jack and go to the setting function and toggle the TV Speaker Sound Output mode to that of Audio Out/Optical Sound Output.
Now you can pair a Bluetooth headphone to the Bluetooth adapter.
A:AnswerHello Liane525, this unit only has one port for those connections, so you would only be able to have one of those devices connected at any given time. ^Michelle
