Whole-home audio systems have always been a pain to set up — with unsightly wires running all over the place — and even wireless systems typically tether you to just one device at a time. But the Monster Soundstage Music System promises to solve those problems once and for all, letting you simply play music all over your house from any source on your network. You can queue up a track on your phone, add to the playlist from your laptop, and change the volume on your tablet (even play different songs on different units at the same time). And because they're made with powerful front- and rear-facing drivers, they deliver great sound across the spectrum. Available in October.
