"Small size, powerful output"5.0 starson by Solitas03
Pros: Great output as compared to my iPhone and iPad speakers. They offer a higher volume range than both of those combined. Very small size takes up little room during travelling. Acts great as speakerphone in car drives that will cut out music for calls
Cons: Was playing a high bass game and the rubber ends did not provide adequate traction to keep the Jambox from vibrating off the table. No ability to control Treble or Bass levels. I was told to talk louder when using the speakerphone by callers
Summary: The portable Bluetooth speaker field is an area most consumers will have to trust user/professional reviews because most stores do not have them on display to compare quality. Be cautious opening the package so you don't have to pay a restock fee if you decide you don't like the quality. For the size though it is awesome and comparing it to the stock speakers of most cellphones or tablets this speaker will win out. Dual functioning as a speakerphone is hard to beat as well! The battery life for my usage has bested the iPad 2!
