Short answer: the JBL Authentics 300 if sound quality matters most, the Tronsmart Fiitune X30 if price matters most. The JBL Authentics 300 ranks #46 of 113 boombox speakers, rated 3.5/5, at $299.95. The Tronsmart Fiitune X30 ranks #54, rated 3.3/5, at $144.90, $155.05 cheaper.
Why pick the JBL Authentics 300: A retro styled smart speaker with both Alexa and Google Assistant, a leather handle and battery power. The catch: Narrow sounding, bass not as deep as others.
The Tronsmart Fiitune X30 is the longer-running, lighter pick. A loud six driver speaker with LDAC Bluetooth, water resistance and a long rated battery. It is rated for 14 hours of battery against 8 for the JBL Authentics 300. At 7.9 lbs (3.6 kg) it weighs noticeably less than the JBL Authentics 300 at 10.8 lbs (4.9 kg). It is rated IPX6, while the JBL Authentics 300 has no water resistance. The tradeoff: 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.
