CakFun Portable Bluetooth Speaker 

Outdoor Waterproof Wireless Dual Speaker System

This speaker is very versatile. Can be used with a laptop, a smartphone or even by itself without a connection.
It comes with a built-in FM radio tuner that scans for your local FM radio stations.

One quick press on the power button puts the speaker into FM mode, while one long press on the power button changes it to Bluetooth mode, ready to pair with your favorite device. Easily connects to any device with a friendly voice to confirm connectivity. The 2000mAh battery promises 8-10 hours of all day listening, but I don't believe it actually lasts quite that long. It does not take very long to recharge the battery.

This bluetooth speaker has better sound quality and more bass tones than the speakers that are factory installed on my laptop which makes listening to music much more enjoyable while working. I haven't yet been able to confirm whether or not it is indeed water resistant, but it is nice to know that a bit of light rain will not hurt this speaker.

I have never heard of this brand, it is Chinese made, but I like this bluetooth speaker, it is well worth the sale price.
