Leander Kahney's pick for MacBreak Weekly episode 377 is the Play:1 speaker from Sonos. This is an easy-to-setup, wireless speaker that can be added to your stereo system.
The Play:1 speaker is a great way to add sound into another room of your house. If you have a Sonos Playbar, then you can even add the Play:1 as a surround sound speaker in your home theater system as well. Sonos speakers are flexible, and just work really well.
Sonos speakers may not be cheap, but the nice thing about them is that you can slowly add more speakers over time. Every time you add a component, it adds more value to the whole stereo system.
