I am guessing that APTX is a given - or is it?
To sort out things:
Option 1
Any device with Bluetooth (e.g. your phone) will stream to the Lumity. Music via A2DP, phone calls via HFP (these are the names of the Bluetooth profiles used to achieve that).
AptX is NOT supported (and not required by the way
)
Option 2
The link you posted is the “TV Connector”, a dedicated device to stream an audio source such as the TV to your Lumitiy. The TV is connected analog or optical to the TV Connector.
It is wireless but uses a dedicated lower power / lower delay compared to Classic Bluetooth. Means optimized for TV watching where lipsynch and echo could be an issue otherwise.
Make sure you get the version where you can see button on the top, not the all black one.
cheers
