Bluetooth Speaker, MixcMax 5W Portable Wireless Stereo Speakers, 20-Hour Play time, IPX7 Waterproof, anti-fall test, range of 20 meters-Army green

Great volume out of this. It's difficult to hold when blasting out sound; it vibrates so much that as it has been attached to my belt loop, it tickles my hip if turned up full.As for the phone answering, it's worse than useless; so unless there's something wrong with mine, definitely don't get it to use this facility.Battery life is brilliant. I'm sure it does every bit of the 20 hours it promises with no fluctuation in the volume. It begins to speak to you saying, "The battery is running low, you need to recharge now". This just comes on and repeats every 10-15 seconds; so you can't listen to it anymore without putting it on charge.

The speaker came in a sealed box. The speakers are light weight and waterprrof. I have put this speaker in the shower when the water was running and the speaker didnt get any water inside. The bluetooth range is about 30 meters at times but other times, its about 20 meters. The microphone works nicely. It picks up strong. The sound is loud and crisp. The volume can go extermely loud which is nice when you're running around doing stuff. I would recommend this speaker.

Whenever a product gets really consistently stellar reviews, I get sceptical that maybe the reviewers were compensated. But I gave this a shot and it really is as good as everyone says. The sound is clear, it has decent bass, and the range is incredible. I played music from my laptop on the ground floor and carried the speaker to the second floor into the shower, no problem. I also took it outside and shut the door, no problem. Really incredible value.

I don't know why but my speaker has stopped working. It does not switch on but still shows a red light.Edit- there was a small reset button near the charging slot and I pushed a pin inside it. Now it's working normally again. A perfect device.
