I have Echo Dots in most of the rooms in my house. Normally, when I start talking to Alexa, only the closest Echo Dot responds.
The Soundbar 700 doesn’t seem to correctly implement that feature, however. Because even when I’m on the other side of the house, talking directly into an Echo Dot, the Soundbar will end up responding. It’s particularly annoying because, since it is much further away, it often misunderstands what I’m saying.
