These sit in different size classes, so this is not a straight ranking comparison. The JBL Xtreme 4 ranks #40 of 83 large speakers by sound quality at $309.95; the Tronsmart Fiitune X30 ranks #45 of 85 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.

The Two Speakers In Full
JBL Xtreme 4: $309.95 Amazon B&H Photo Video eBay
Newer model: the JBL Xtreme 5, ranked higher, rated 4.6/5.
Pros: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Independent reviews find the midrange detailed and the sound clear, punchy and refined for outdoor use; it also reaches a strong 106dB maximum level and has excellent real-world battery life.
Cons: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume. The front-facing layout has only modest off-axis consistency, Bluetooth latency is high for video, and the default balance benefits from EQ adjustment. There is no aux input, so wired sources are not supported. Out of the box it leans bass-boosted, with a dip between the upper bass and midrange that EQ cannot fix, and it pushes the upper mids and treble at high volume. It is also expensive.

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. The evidence is listening comparisons, not measurements.
