Product 2: Ultimate Ears Wonderboom 4 Speaker
No score yet
EQ customization
Product 1: JBL Flip 7 Portable Speaker
4.3

The move to a 7-band EQ is a major usability win and is frequently praised; caveats include Playtime Boost disabling EQ adjustments and some complaints about not saving multiple custom profiles.

Product 2: Ultimate Ears Wonderboom 4 Speaker
2.1

EQ control is mostly limited to preset modes such as Outdoor Boost and Podcast mode, and several reviewers found these modes of limited usefulness. A minority source claims full app-based EQ options, but the broader set of reviews does not support that experience.

Float capability
Product 1: JBL Flip 7 Portable Speaker
4.0

One review claims the Flip 7 can float while playing, but this is not consistently verified across sources, so treat it as a nice-to-have rather than a core guarantee.

Product 2: Ultimate Ears Wonderboom 4 Speaker
4.1

Float behavior is generally positive, but multiple sources mention practical caveats: audio may not play while floating, sound can change when wet, and it may tip over in the water so the sound does not project as expected.

Frequency response balance
Product 1: JBL Flip 7 Portable Speaker
3.8

Most reviewers hear punchy, fun tuning with good bass for the size, but some report a V-shaped balance (boosted bass/treble), midrange that can feel recessed or shouty, and thinner sound when Playtime Boost is enabled.

Product 2: Ultimate Ears Wonderboom 4 Speaker
4.2

Tuning is often described as balanced for the size, with punchy bass that does not overwhelm mids and highs at reasonable volumes. Several reviewers also note bass reduction or a thinner presentation when using outdoor-style EQ modes or pushing volume very high.
