JBL Charge 6 vs Ultimate Ears Boom 4

Last updated: October 5, 2026

Short answer: the JBL Charge 6. It ranks #12 of 164 medium speakers at $149.95, a clear step above the Boom 4 at #110 for $100.08. The gap is not just rank order: the tuning and battery life differences are real and noticeable.

JBL Charge 6 vs Ultimate Ears Boom 4

The Charge 6 corrected JBL’s own past mistakes. Compared to the Charge 5, it has a flatter frequency response through the mids and treble, since the 5 was noticeably rolled off up high. It is not neutral out of the box (some boosted bass, recessed mids, brightness above 2kHz), but reviewers note it is more balanced than its predecessor. Battery life is rated at 24 hours, a real advantage over the Boom 4’s 15.

The Boom 4 barely moved the needle over the Boom 3. Its pros are mostly convenience upgrades: it is IP67 rated, floats, and finally charges over USB-C instead of the older Booms’ Micro-USB, plus it adds customizable EQ and speaker pairing through the UE app. But the notes are blunt that it is not much of an improvement over the old model, with weak bass extension, thuddy low end, and audible distortion above 90 percent volume.

Everything else worth noting: both speakers support true stereo pairing and app control, and the Charge 6 adds Auracast party mode and USB-C power bank output, neither of which the Boom 4 offers.

Buy the JBL Charge 6 for the flatter tuning, the much longer battery life, and the extra Auracast and power bank functionality.

Buy the Ultimate Ears Boom 4 if you specifically want a floating, USB-C charging Boom at a lower price and don’t mind that it is a minor refresh rather than a real step forward in sound.

JBL Charge 6 ranking card

Older models: the JBL Charge 5 (ranked lower, rated 4/5), the JBL Charge 4 (ranked lower, rated 3.5/5), the JBL Charge 3 (ranked lower, rated 3.2/5) and the JBL Charge 2 (ranked lower, rated 3.2/5).

Pros: Seems more neutral than the Charge 5. Flatter frequency response through the mids and treble as the Charge 5 was quite rolled off up high. Use this EQ from Joy/Oluv and turn down the lowest bass slider for the best sound quality. Oluv has even more paid EQs specifically for the GG and TL models indoors and outdoors here. IP68 protection, a 7-band app EQ, Auracast, USB-C charging and a power bank output. Measured bass extension of 53Hz (-10dB).

Cons: Still some boosted bass by default. Mids are recessed. Bright above 2kHz. Quite a V shaped frequency response.
