Short answer: the Sony ULT Field 3, since the Ultimate Ears Megaboom 3 is not stereo and has barely any bass. The Megaboom 3 is IP67 rated, floats and survives drops from up to 1 meter, but that is where its advantages end. The Sony is IP67 rated, dustproof and water resistant and costs $208 against $191.99, though it sounds a bit hollow with boosted treble.
Buy the Sony ULT Field 3. It is rated higher for sound quality, and saving $16.01 with the Ultimate Ears Megaboom 3 does not make up for the sound-quality gap.
