Can a Hopper3 be successfully paired with Amazon Echo, so that the Echo could be used as an inexpensive speaker bar?
The H3 can send audio via Bluetooth.If the Hopper 3 can send it's audio via Bluetooth, then yes it should work.
The echo does receive Bluetooth audio, i use it with my iPhone all the time to stream from various apps but I have not been able to pair the echo with my Hopper3.
The question is does the Echo receive bluetooth audio or is it web based only.
