While discussing bluetooth speakers it's always of utmost importance to consider it's portability, built quality , design, probable run time in single charge and obviously and most importantly it's sound signature.
Now come to the points one by one.
It's a tiny compact and premium looking rectangular shaped boom box you should say. The small form factor actually makes it super portable. Avail it in three different colours as per your choice between blue, red and black. Seriously choose any one of them, no matter which one, it will be a thing of spectacle. The rubberised uni body design gives you a perfect cool and premium look. Moreover it's very light too. You'll not find it difficult to carry your sound system in you bagpack every time you start sailing anywhere. ??????
Now coming to the connectivity options. You can use this speaker with the help of bluetooth and any Auxiliary cable.
It has the potentiality to deliver continuous service for at least 5 hours straight if used in full sound. If used in 60-70 % volume then you can just forget about charging. It'll go on at least 8 hours definitely making it a good value for money. Honestly I'm super excited regarding it's run time.
Now talking to the main point, the sound, I must say it sounded very moderate to me. Let me tell you that the single speaker it has is of 3 WRMS , thereby making it a quite loud speaker in it's price range . You can easily use it for house parties. Honestly your friends will not be disappointed with it's sound. Though don't ever expect too high bass from it. Remember that we are here talking about an entry level bluetooth speaker that too from a brand like JBL. it's not certainly a premium one. Apart from it, there's no complaint regarding mids and highs. The mids and highs are crystal clear and specially the musics from genres like bollywood and rock will just blow your mind up.
Considering all the aspects I must say that it's a real value for money product. Buy it and you'll forget about your thousand dollar music system too I bet . Your premium sound system too will never come to compete with it in terms of portability and convenience.
