Beats branding would be dangerous. A large proportion of the "audiophile" community they seem to like marketing the HomePod to will dismiss such a device instantly, potentially alienating a lot of prospective buyers.
But beyond that, I don't think $350 is unreasonable for a smart speaker, I just think it's unreasonable for a smart speaker that pales in comparison to far cheaper ones when it comes to the "smart" aspect. Based on how many terrible bluetooth speakers are sold every day, I don't think massively better audio quality alone is enough to sell units. If anything, take Siri out entirely and market this new one as a Sonos Play:1 competitor that can work as either a Wifi or bluetooth speaker and nothing else. For the value proposition, make it splashproof and double as a speakerphone. Done, it'll sell like hotcakes.
