Question Bluetooth Audio With 4K Disc Player

[MarsColonist]

I was looking at some 4K disc players and found the Sony UBP-X800M2 appears to support bluetooth, but costs way more than this Sony UBP-X700 so I'm wondering if it is possible to connect a bluetooth dongle to the UBP-X700 and connect whatever wireless bluetooth headphones I use on my PC with the UBP-X700 for watching 4K movies...? And if possible, is it a bad idea, like would the audio be worse quality or something?

Headphones are Sony WH-1000XM4

Sony said no bluetooth headphones for UBP-X700 but I guess I was just thinking about this as a possible workaround because the UBP-X800 looks like it costs almost double the price.
