If you're looking for a speaker to accompany you on every summer adventure, the UE Wonderboom 2 is a great option. The lack of an integrated microphone is annoying since it means you can't access a voice assistant, but it's a small price to pay for a speaker that floats.

No microphone, Distortion increases with volume, microUSB charging

I have owned one for a while now. Sound is excellent as with battery life. Bit fiddly for startup due to double top buttons needing to be depressed at the same time. Really like the auto turn off if not used for a time. I see pricing is easing, so would suggest this is now in the reasonable purchase price range. Not keen to try supposed water proofing.... (why would you?) Great product.
