The JBL Flip II Speaker (Black Edition) is a portable Bluetooth enabled speaker. It can be bought in stores or online. The FLip II is slightly smaller in size compared to others in its class. Even though it is smaller, the music output in terms of volume and bass is amazing. Music can be played on the speaker by either connecting your phone via Bluetooth or by using and AUX Cable which can be bought for about Rs. 150/- online. It is quite easy to pair your phone via Bluetooth. The range of the speaker isn't great and this is the only slight disadvantage. Like stated before, music quality is great be it outdoors or indoors. Though I have not played music using the AUX Cable, I think that there shouldn't be any problem. The battery life is just above average. JBL's website claims that the speaker will run for about 4 - 5 hours. This is not true. While connecting and playing via Bluetooth, it lasted for about 3 - 3.5 hours only. 3 hours is not bad though. A good thing
