Ditching a TV remote for simple voice commands sounds great in a lot of circumstances. And, with a little help from Alexa (and some other digital assistants down the road), the Sonos Beam comes as close to executing that as anyone has so far. And while the Beam won't let you toss your clicker just yet, it's still one of the best home audio devices around, even with its $400 price tag. The Beam is the latest in the Sonos series of speakers meant to pull double duty, handling both music as well as the sound that comes from your home entertainment center and TV. It's the smallest and cheapest option in the Sonos lineup to handle that kind of task, sliding in under both the Playbar and the Playbase.
