Companies have finally caught on to Sonos' style of multi-room audio and are trotting out similar products of their own. Philips is jumping on the bandwagon as well, and at CES this year, the company is debuting its izzy line. Made up of four speaker options, the izzy series aims to blanket your house with audio and it has a key feature that differentiates it from the competition. Most multi-room setups require an app to handle the configuration, but that's not the case here. Philips' izzy doesn't need a router or any extra software as the speakers create their own network and can be paired in a group of up to five with the push of a button.
