Not many. Most people are uncritical listeners and unless it’s really really really bad people will say that the sound is good enough. And at $30 it’s not worth the hassle to return it.
First of all, none of us know how many Echo's, Google Homes, or HomePods were returned.
Second, the audio of an Echo, especially Echo Dot, is really, really bad (and remember, we do know that the Echo Dot is the best selling Alexa device). But it doesn't matter, because audio quality is not why someone buys an Echo. That's why I keep harping on the inanity of comparing the HomePod to the Echo: They are in different markets.
[doublepost=1526592181][/doublepost]Oh by the way, for anyone who does want a HomePod, and if you've got a MicroCenter near you, they're going for $300 there. If they're still at the price when Apple releases AirPlay 2, I'll pick up a second one myself.
