Short answer: the Bose SoundLink Color II. It ranks #98 of 136 medium speakers by sound quality at $107.15; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, so there is little reason to consider the other one.
What the Bose SoundLink Color II offers: Soft-touch rubber coating is comfortable to hold and tough enough for bumps and scrapes. IPX4 splashproof. Supports multipoint pairing to two devices at once. Watch for: Boosted bass on Color II. Not as deep of bass as other models. Lacking midrange detail. 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 Color II. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so the other one has nothing left to offer.
If sound quality matters at all to you, skip the Ultimate Ears Megaboom 4. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
If battery life is a priority, the Ultimate Ears Megaboom 4 is rated for 20 hours versus 8 hours for the Bose SoundLink Color II.
There is a real gap in water resistance: the Ultimate Ears Megaboom 4 at IP67 (brief submersion) against the Bose SoundLink Color II, which has IPX4 (splashing).
