I bought this bluetooth speaker 2 months ago , and here are my general reviews of this device. First of all there is a great issue with the Bluetooth connectivity. I had to pair these bluetooth speaker with my device 6 to 7 times to make it work. Secondly the audio output is much less than expected. The bass quality is very average. the bluetooth speaker keeps on getting disconnected with my device many times during playback. Also I can't receive my phone calls through this bluetooth speaker. The battery life of this bluetooth speaker is also much less than expected only two to three hours. I would recommend to go for some other option at this range.
