18 Hour Battery.

IPX5 Water resistance.

LED Lights that change colour.

Connect up to 2 Bluetooth devices at the same time.

See pics of the speaker i am selling, still in box unused, and the one i am keeping to give an idea of size, connections etc.

I bought 2 of these brand new with the expectation to connect both together and use as stereo. 

Very impressed by the sound and volume, so much so the 2nd speaker has never been used and is still in box, as the single speaker is more than loud enough to fill any space.
