This speaker I won in my previous organisation. This is the main reason I like it. However, talking about the quality of the speaker, its bass is just awesome. I use speaker only for bass. It gives me the feel of listening music. There is no disturbance in the sound. The is crystal clear. One of the positive point in this is it is easily portable. Though somewhat costly but it gives you the satisfaction of investing the money in right product. If you are travelling somewhere far, this speaker would be your best friend. It gets charges within 1-2 hours and battery back up is approximately 6 hours if played continuous. I hope this information is sufficient to think for buying it.
