One of the more practical pieces to come out of CES 2014 is the BRAVEN Mira Speaker. Just like phones, speakers are quickly getting smaller and smaller while also somehow getting more powerful, and these speakers exemplify that.
The speakers work on a Bluetooth signal, so you won't have to worry about a bunch of complicated wires getting tangled or having to trip over them while you carry your speaker set with you. The speakers themselves are also quite small, so they eliminate the need to carry around a bulky set up just to get some sound when you're on the go.
Don't mistake their size for a lack of power, though. These speakers comfortably fill up the room with crystal clear sound and essentially make your bigger and heavier set obsolete. The BRAVEN Mira speakers run on a rechargeable lithium battery, but can easily give you up to ten hours of sound on a single charge. Better yet, they're waterproof just in case you weren't sold yet.
