Short answer: the JBL Authentics 300 if sound quality matters most, the Tronsmart Fiitune X30 if price matters most. The JBL Authentics 300 ranks #40 of 89 boombox speakers, rated 3.5/5, at $299.95. The Tronsmart Fiitune X30 ranks #48, rated 3.3/5, at $144.90, $155.05 cheaper.
Why pick the JBL Authentics 300: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). The catch: Narrow sounding, bass not as deep as others.
What the Tronsmart Fiitune X30 does well: A three-way, six-driver design (racetrack woofer, two midranges, two tweeters and an upward-firing driver) with 80W, Hi-Res certification, LDAC, a claimed 14 hours of battery and IPX6. The catch: Side by side it clearly lost to the Harman Kardon Go + Play 3, the Soundcore Boom 2 and the EarFun UBoom X: listeners described muddy, dark mid-bass that fails to reproduce low notes, dull and underemphasized treble, and a boxy, sterile sound at low volume next to the JBL Xtreme 4.
Buy the JBL Authentics 300 when sound quality outweighs the price for you, and the Tronsmart Fiitune X30 when the price outweighs sound quality instead.
If water resistance matters to you, the Tronsmart Fiitune X30 at IPX6 (powerful water jets) holds up far better than the JBL Authentics 300 at no water resistance.

Tronsmart Fiitune X30: $144.90 AliExpress Tronsmart Best Buy eBay
Pros: A three-way, six-driver design (racetrack woofer, two midranges, two tweeters and an upward-firing driver) with 80W, Hi-Res certification, LDAC, a claimed 14 hours of battery and IPX6. It plays loud with a lot of mid-bass, reviewers found good separation of instruments and voices, and some listeners found it warm and full at high volume.
Cons: Side by side it clearly lost to the Harman Kardon Go + Play 3, the Soundcore Boom 2 and the EarFun UBoom X: listeners described muddy, dark mid-bass that fails to reproduce low notes, dull and underemphasized treble, and a boxy, sterile sound at low volume next to the JBL Xtreme 4.
