I had a few legacy Bose SoundLinks lying about. Thought this might make them useful but be aware that the Bose SoundLinks need the AUX button pressed before any input is accepted from the 3.5mm input. This made the Echo Input less than ideal for this setup.
Maybe just early days but when compared with Echo or Echo Spot, the microphone is not as sensitive. Probably uses the same inferior microphones found on the Echo Dot.
Amazing!! This is what I wanted, the idea of being at mercy of the manufacturers with below the class audio at a higher price is not something that I was happy with. But this is a a game changer. Smart move amazon. I am so happy to use my LogitechZ623 with Alexa and it works like a charm.
