Just wanted to add my 2 cents to the product---- I bought 2 of these, gave one to my parents, and kept one for myself.
We have had them over a year, and they are excellent! great battery life when unplugged.. however it does lower the overall sound output slightly. Bluetooth pairs nice and easy, no issues. And it can charge your device with a usb jack on the back.
Only feature difference with the Jawbone Jambox is that the Jambox functions as a speakerphone, but otherwise is just overpriced.
I highly recommend the SoundFreq Soundkick!
