These are not really the same size class, and that is the honest framing here. The LG Xboom Bounce ranks #33 of 105 large speakers by sound quality at $98; the Sony ULT Field 3 ranks #75 of 175 medium speakers by sound quality at $208.
Why pick the LG Xboom Bounce: Unique spherical design. It keeps a wired aux input, which the Sony ULT Field 3 lacks. The catch: Bass extension not as deep as the top speakers.
The case for the Sony ULT Field 3: IP67 rated, dustproof and water resistant. It supports LDAC Bluetooth, which the LG Xboom Bounce lacks. The tradeoff: Sounds a bit hollow, a bit boosted in the treble.
Buy the LG Xboom Bounce at $98 for a large speaker, or the Sony ULT Field 3 at $208 for a medium speaker instead.

Same family: the Sony ULT Field 1 (smaller model, ranked lower, rated 3.1/5), the Sony ULT Field 7 (smaller model, rated 3.2/5), the Sony ULT Tower 10 (smaller model, rated 3.9/5), the Sony ULT Field 5 (larger model, rated 3.5/5), the Sony ULT Tower 5 (larger model, rated 4.5/5), the Sony ULT Tower 7 (larger model, rated 4.7/5), the Sony ULT Tower 9 (larger model, rated 4.2/5) and the Sony ULT Tower Max (larger model, rated 4.8/5).
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.
