If there is a portable speaker that you might want to consider owning, how about taking the wireless route with the Genius SP-900BT Portable Bluetooth Speaker? This is a device that also sports a built-in microphone, but we will get to that afterwards. Basically, the Genius SP-900BT will be able to hook up to your smartphone or tablet sans wires. This particular compact speaker will allow you to listen to audio or music directly from your smartphone or tablet at volumes which can be cranked to pretty high levels, while letting you attend to incoming phone calls and conference calls, hands-free.
Synchronizing the 2-watt SP-900BT is as simple as using a press of a button to your Bluetooth-enabled smartphone or tablet, where it will play nice within a distance of up to 30 feet. Should there be an incoming phone call when the music is playing, the SP-900BT will inform you with a ring. Answering the call will allow you to talk and listen without requiring you to touch your handset at all. No idea on how long the 700mAh lithium ion rechargeable battery is able to last though.
