Ordered two Echo Studios and they arrived the day after the release day, I already had an Echo Sub so I paired them up and added the sub, set up was easy, just plugged them in and they were instantly recognised, then just had to set up the speaker group.
The sound is outstanding, it can get very loud and the bass hits you in the chest at higher volumes (they like higher volumes but I doubt your neighbours will).
I originally had them on the carpet but had some spare spiked speaker stands which improves the sound even more as does turning off the spatial setting. I haven't tried with Atmos but that only works with the firestick 3rd Gen (diamond shaped version), 4k Firestick and Firestick Box, all of which are not yet available from Amazon Australia (please release soon Amazon).
Overall very impressed and a good buy.
