The manufacturer states a limitation
Samsung’s Multi-output Audio guide explicitly says support can depend on model and geographic area. A missing option should therefore trigger a compatibility check before repeated pairing or a factory reset.
Record the complete TV model, software and region context. A screen-size or marketing-series name may cover several variants, so use the full model where the manufacturer requests it.
Check the intended combination
The documented arrangement concerns TV speakers and Bluetooth headphones together. Do not infer that a soundbar plus headphones or two arbitrary headphones must be supported. Identify the exact listening goal and compare it with the model’s manual.
If the feature exists, follow its pairing prompts using the headphone maker’s own discovery procedure. If it does not, seek a supported listening arrangement for that hardware instead of claiming an invisible setting can be unlocked.
Keep compatibility and connection distinct
A headset connecting successfully for ordinary Bluetooth output does not establish simultaneous speaker output. Conversely, a missing simultaneous-output feature does not prove the headset itself is faulty.
This is a feature-scope check based on Samsung’s regional documentation, not a hands-on compatibility verdict for every European model. Preserve that distinction when asking the manufacturer or retailer for help.
Questions answered
Can I infer support from a similar Samsung TV?
No. Samsung explicitly limits support by model and geography.
Does ordinary Bluetooth audio prove Multi-output Audio works?
No. Simultaneous outputs are a separate documented feature.
