JBL Flip 6 vs Ultimate Ears Wonderboom

Last updated: October 12, 2026

Short answer: the JBL Flip 6. It ranks #13 of 175 medium speakers by sound quality (rated 4.2/5) at $79.95 and is still sold new; the Ultimate Ears Wonderboom ranks #112 (rated 2.9/5) and is discontinued, so it is only an option used. The Ultimate Ears Wonderboom’s replacement, the Ultimate Ears Wonderboom 4, is rated 2.9/5 at $74.50.

JBL Flip 6 vs Ultimate Ears Wonderboom

The JBL Flip 6 is the better-sounding pick. A very neutral speaker, very small, almost pocket size, a huge sound quality leap over the JBL Flip 5. It links with other speakers (PartyBoost up to 100 speakers), which the Ultimate Ears Wonderboom cannot. It has an adjustable EQ, which the Ultimate Ears Wonderboom lacks. It charges over USB-C rather than Micro USB. The tradeoff: Some slight upper mids emphasis.

The Ultimate Ears Wonderboom is the lighter pick. IP67 rated and floats. At 0.9 lbs (425 g) it weighs noticeably less than the JBL Flip 6 at 1.2 lbs (544 g). Watch for: Not stereo, barely any bass, recessed treble.

Buy the JBL Flip 6. It is rated higher for sound quality and still sold new, while the Ultimate Ears Wonderboom is discontinued.
