The REX speaker will pair with your mobile device or computer using Bluetooth technology, and with a built-in noise cancelling microphone, the REX can at the same double as a Bluetooth handset for you to make your calls with. For iOS users, the REX speaker is also expected to be compatible with Siri and comes with a button that when depressed for 1 second, will launch Siri on your iOS device, letting you interact with it through the speaker. Powered by a medical-grade lithium-ion battery, the REX promises 6 hours of usage before requiring a recharge which is as simple as plugging it into your computer via USB. If you’d like to learn more about REX, such as its technical aspects or perhaps donate to its Kickstarter project (a pledge of $80 will net you the speaker upon successful funding), head on over to its page for the details.
