The Two Speakers In Full
Sony ULT Field 3: $138.00 Amazon eBay
Older models: the Sony XB33 (rated 3.4/5), the Sony SRS-XE300 (rated 2.8/5) and the Sony SRS-XB30 (rated 2.6/5).
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.
