#60 Sony ULT Field 3: $138.00 Amazon eBay

Pros: 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.

Cons: 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.

Related speakers: Sony ULT Field 1, Sony ULT Field 5, Sony ULT Field 7.

How it compares: Just above it: Bose Soundlink Mini - $13 cheaper, 14 fewer hours of battery life. Just below it: Xiaomi Mi Portable - $83 cheaper, 11 fewer hours of battery life.
