Which compact speaker fits your carry style and listening controls?

Pick the Bose for a pocket-size speaker with a utility strap and app-adjustable EQ, provided floating is not required. Pick WONDERBOOM 4 when floating capability or its onboard Outdoor Boost and Podcast Mode fits your use. These are feature-fit choices; the available sources do not establish which sounds better or is more durable.

The buying question

Should you prioritize Bose's pocket-size utility strap and app-adjustable EQ, or WONDERBOOM 4's floating design and onboard listening modes?

The Bose is shaped and described for pocket or strap carry and explicitly does not float; WONDERBOOM 4 is a portable 360-degree speaker that the manufacturer says floats, with Outdoor Boost and Podcast Mode.

Quick verdict

Choose Ultimate Ears WONDERBOOM 4, Black if

  • Floating is an important requirement for poolside or water-adjacent placement.
  • You would rather use the named Outdoor Boost and Podcast Mode on WONDERBOOM 4 than tune EQ in an app.

When the recommendation changes
  • If a speaker must float, the documented difference favors WONDERBOOM 4; if pocket/strap carry and app EQ matter more and floating is unnecessary, the Bose feature fit may be preferable.

The differences that matter

Carry Placement And Water Use Fit

Bose SoundLink Micro Portable Bluetooth Speaker (2nd Gen), Black

Bose describes the SoundLink Micro (2nd Gen) as pocket-size with an updated utility strap. It states that this model sinks and does not float; the product page also lists IP67 water and dust protection.[1]

Ultimate Ears WONDERBOOM 4, Black

The exact U.S. WONDERBOOM 4 page identifies Active Black and describes a portable 360-degree speaker with IP67 protection that floats in water.[2]

What this changes: Both manufacturers list IP67, but only WONDERBOOM 4 is documented to float. That can change retrieval and placement choices around water; it is not evidence of stronger waterproofing or better durability. The Bose strap and pocket-size design suit a different carry preference.[1, 2]

The better fit depends on your priorities

App Adjustable Eq Vs On Speaker Listening Modes

Bose SoundLink Micro Portable Bluetooth Speaker (2nd Gen), Black

Bose says its app provides adjustable EQ for bass, treble, and mid-levels; its app also manages the programmable shortcut button.[1]

Ultimate Ears WONDERBOOM 4, Black

WONDERBOOM 4 has an Outdoor Boost control and a Podcast Mode described as an EQ mode for vocals.[2]

What this changes: This is a choice between the Bose app's adjustable EQ/shortcut workflow and the UE page's named listening modes. The sources do not establish that either product lacks the other product's kinds of controls, or that one setting sounds better.[1, 2]

The better fit depends on your priorities

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Compare current delivered offers and the exact seller condition and included items. A higher price would need to be justified by the carry, floating, or control features that matter to you; this research does not set a value winner.

Insufficient price-history evidence to recommend purchase timing. Compare current delivered offers and confirm the exact model and package.

Limitations

  • The Bose manufacturer page identifies the SoundLink Micro (2nd Gen) family but does not print the selected Black marketplace listing's part number. Confirm the exact model/color and seller package before purchase.
  • This comparison uses manufacturer-described features, not hands-on testing. It does not establish sound-quality, loudness, battery-life, water-resistance, or durability superiority.
  • WONDERBOOM 4's floating claim does not mean Bose lacks water protection: both manufacturer pages list IP67, while Bose explicitly says the Micro does not float. Follow each product's care guidance and do not treat this as a submersion recommendation.

Questions shoppers ask

Does the SoundLink Micro (2nd Gen) float?

No. Bose says it sinks and does not float. Bose also lists IP67 water and dust protection; that rating and floating behavior are separate points.

What are the main listening-control differences?

Bose describes adjustable EQ in its app and a programmable shortcut. Ultimate Ears describes an Outdoor Boost control and Podcast Mode on WONDERBOOM 4. The available product pages do not prove that either speaker lacks other control options.
