Questions about this item

What audio outputs must my TV or stereo already have for the transmitter mode to work?

The adapter connects through a 3.5 mm AUX or RCA input, so the source device needs one of those analogue outputs.

Will the adapter stay paired with my existing Bluetooth 5.0 headphones after a power cycle?

Yes, a power-off memory chip restores the previous mode and pairing automatically when the unit is turned back on.

How can I confirm the link is running at the specified 10 Hz to 20 kHz response after setup?

Play audio and verify sound is audible across the full frequency range; the adapter supports 10 Hz to 20 kHz response per its specifications.
