Bluetooth Speakers

I am looking at two different speakers for the upcoming summer months. I was looking for a Bluetooth speaker that can be used for pool parties, on the beach etc. Basically waterproof and the loudest possible without needing a mini cart to carry it.  I came across two the JBL XTREME 2 and the UE MEGABOOM 3 that i narrowed down to, but was wondering if anyone on here has had experience with either of them or can give some more insight. Thanks so much guys!

I have had good luck with JBL products-  not sure of that specific model though.

well, I never tried them.
instead, I am using OontZ Angle 3 Portable Bluetooth Speakers which I bought from Reecoupons.
They are easy to carry, portable and have a louder voice with 3D bass effect.
