Short answer: the Bose Soundlink Revolve+ if sound quality matters most, the Ultimate Ears Megaboom 4 if price matters most. The Bose Soundlink Revolve+ ranks #46 of 136 medium speakers at $230. The Ultimate Ears Megaboom 4 ranks #132 at $200, $30 cheaper.
What the Bose Soundlink Revolve+ offers: True 360° sound stays consistent no matter where you stand. Built-in carry handle, useful even with wet hands; can hang from a hook via carabiner. ~12 hour battery at medium-high volume. Watch for: Overly boosted bass, warm sounding. Boosted mids. Rolled off treble.
What the Ultimate Ears Megaboom 4 offers: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together. Watch for: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
Buy the Bose Soundlink Revolve+ if sound quality is the priority over the price, or the Ultimate Ears Megaboom 4 if the price is the priority over sound quality.
The Ultimate Ears Megaboom 4 is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.
