I have used this Bluetooth speaker from zoook for almost a year now.and I must say that I am surprised with its performance.very good battery life.ideal for indoor playbacks.
The most interesting thing is that it has LED lights all over the output area.they are music synced.which you get in very high end devices(10-15k)
connects with almost any Bluetooth enabled devices.
pros:-
1)Incredible battery life.can last more than 3 hours on a full charge and continuous playing
2)Has led lights which can be toggled and are synced with the audio
2)very good bass output.you can even feel the bass thumps
3)good reception length.
4)appropriately loud.good for single room
5)can compete with other high-end Bluetooth speakers
6) very good build quality
7)superb connectivity:- usb, sd card, aux cable, fm radio
8)can receive calls even.has built in mic as well
Cons:-
1)not suitable to take for outdoor parties
2) takes long in the first connection for being established
nothing more as such
But every con is justified by its long pros list & the price segment.
For a price almost 1k(I got a deal for Rs.899) its a killer one.you wont be disappointed.
