Short answer: the Sony ULT Field 3 on measured sound quality, the Ultimate Ears Roll 2 on price. The Sony ULT Field 3 ranks #57 of 136 medium speakers at $148. The Ultimate Ears Roll 2 ranks #125 at $100, $48 cheaper.
What the Sony ULT Field 3 offers: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone. Watch for: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together - turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
What the Ultimate Ears Roll 2 offers: Thin, flat profile fits easily in a bag or purse; light at 0.73 lb. Built-in bungee cord for hanging from a hook, nail, or door handle. Life-resistant waterproof/dustproof shell. Watch for: Not stereo. Barely any bass, rolled off treble off axis
