There are only a couple of speakers out there that are good outdoors, the Xiaomi Bluetooth Outdoor Speaker is awesome in terms of sounds and it is water repelant meaning it can take a few splash especially when you are travelling and its raining or mountain hiking and waters are splashing. I have full tested the speakers sound and to be honest the sounds are pretty loud, it can fill the room of 60 square meter with good music.
