Avantree CK121 AUX Bluetooth audio receiver
Question about Avantree CK121 AUX Bluetooth audio receiver
Can I pair this device with wireless headphones? Can I plug this unit into the jack on my PS4 controller so that the sound is sent to my Bluetooth headphones?
This is not possible with Avantree CK121. For your project there is, for example, the Audikast Bluetooth aptX transmitter from Avantree.
No, that should not be possible. The device is a receiver and not a transmitter.
