These sit in different size classes, so this is not a straight ranking comparison. The JBL Xtreme 4 ranks #43 of 120 large speakers by sound quality at $309.95; the Tronsmart Fiitune X30 ranks #54 of 113 boombox speakers by sound quality at $144.90.
They are tuned very differently. In a side by side sound test, listeners found the Xtreme 4 crisper with deeper bass at low volume, and the X30 boxy and sterile there. At high volume the X30 sounded fuller and went louder.
The Xtreme 4 is measured at about 106dB, and it is IP67 with a replaceable battery, a power bank and Auracast. The X30 is IPX6 with LDAC and a claimed 14 hours.
Evidence: The X30’s rating comes from listening comparisons, not measurements.
Buy the JBL Xtreme 4 ($309.95) for a large speaker; the Tronsmart Fiitune X30 ($144.90) suits a boombox speaker instead.
Battery life favors the JBL Xtreme 4: rated for 24 hours against 14 hours for the Tronsmart Fiitune X30.
