It's almost trivially easy to buy a multi-room audio system at this point, but what if you want stylish audio to go with your designer home? Don't worry -- Bang & Olufsen has you covered. The Danish brand has launched its own platform, BeoLink Multiroom, that pipes music throughout your home. While that concept isn't exactly novel, B&O is counting on simplicity to reel you in. All you do is tap devices to either start playing or link them to playback elsewhere. You might tap the BeoSound Moment (the company's adaptive music hub) to start listening in the living room, and a BeoPlay speaker to carry that sound into the kitchen. While you can use either a BeoMusic app on your phone or a BeoRemote One to steer the sound, you don't have to depend on controllers as much as you would with some rivals.
