"Bluetooth wireless speakers have becoming extremely popular over the past couple of years. They can be used with multiple devices and are powerful enough to provide music for an entire room. They are also small enough that you can easily throw them in your backpack or laptop bag. LUXA2 has a new Bluetooth speaker in their GroovyW, but it is not your ordinary Bluetooth speaker. It comes with a removable wireless / wired charging station giving you 4000mAh of extra power for your portable device. The GroovyW also supports NFC for pairing, has touch panel controls, a microphone to take calls and comes with a companion App for both iOS and Android."
