Question about Samsung Qe65q9fn

The Bose has an RCA connection, I see. But that's for speakers, not headphones, isn't it? I want to connect headphones to the TV, not directly via Bluetooth. Thanks

Hier wäre eine Soundbar mit Bluetooth Bose SOLO 5 (Compact Soundbar, Schwarz)
Und diese mit WLAN; LG SJ8 (Soundbar mit Subwoofer, 300W, WLAN, Grau / Schwarz)
