A:AnswerFrom what I can tell, the N5300 is the 2018 model while the M5300 is the 2017. The N5300 should have these advantages over the M - HDR, higher brightness, 802.11ac wireless vs dual band N, 2018 Samsung software. The M will have better black levels.
A:AnswerThis television does not support Bluetooth. You'll need a Bluetooth transmitter connected to this television that has an optical audio input jack.
A:AnswerIt doesn't have its own Bluetooth connection. Also, it doesn't have a headphone jack so you can't create a Bluetooth connection with a Bluetooth transmitter either.
A:AnswerI have looked high and low and I can't find one on this tv. I've tried to find a definitive answer thru the manuals and spec sheets but I would have to say there is not a headphone jack.
