The speakers will feature a battery that promises a 30 hour battery life, and users will be able to keep track of the battery life via the accompanying app. Thanks to its Bluetooth connectivity, users will also be able to use the speakers to listen to their calls. Priced at $300, the Pillar speaker is expected to go on sale in 2013, and if you’ve got enough cash to spare, it seems that you could even buy multiple Pillar speakers and set them up around the house and have them all stream music once you have your mobile device within range, pretty cool huh? We can’t really speak for its audio quality since we have yet to try it for ourselves, but we suspect that these speakers are aimed more towards those who are interested in wireless music streaming and portability, rather than the audiophile.
