I bought these bluetooth speakers 3 months ago. So , here are my general reviews about this device. First of all the audio quality is average , not good perhaps. You can still here lots of noise while listening to music in loud volumes. The audio can get some time is very harsh and unbearable to listen. The bass effect of these speakers is also bad. The sound is loud but distorted. also there are some issues with the Bluetooth connectivity as it keeps on disconnecting with the device again and again. The battery life of these speakers is normal. Therefore , I would not recommend others to buy these speakers , at this price segment.
