Premium 360-degree floating waterproof speaker for outdoor adventures
UE Wonderboom 3: The premium outdoor waterproof speaker for audio quality seekers
At $100, the UE Wonderboom 3 is the most expensive speaker in this comparison and the one with the best audio performance. 360-degree sound, 14-watt drivers, IP67 waterproofing, and the ability to float if dropped in water — paired with Ultimate Ears' audio tuning expertise — produce the best-sounding compact waterproof speaker at any price under $100.
What works
360-degree sound from a cylindrical design with dual passive radiators provides more consistent audio coverage than front-firing speakers. For outdoor group settings — picnics, barbecues, pool parties — everyone hears the music at similar volume regardless of where they're standing relative to the speaker.
Outdoor Boost mode re-EQs the speaker specifically for open environments — it increases high-frequency presence to compensate for the lack of reflective surfaces that indoor spaces provide. Press and hold the Outdoor Boost button and outdoor listening improves noticeably versus the default indoor tuning. The result is cleaner, better-projected sound outdoors compared to indoor-tuned speakers that sound thin outside.
IP67 waterproofing covers submersion, and the speaker floats — if it falls in the pool or lake, it bobs to the surface intact rather than sinking. This is a practical design consideration for pool use specifically.
14W audio output is the loudest in this comparison and the clearest at maximum volume — competing speakers at 10W or less compress and distort at high volumes.
What doesn't
No speakerphone microphone means the Wonderboom 3 is speaker-only — you need your phone for calls. At $100, this is a genuine omission that the Sony SRS-XB100 ($60) doesn't have.
At $100, the price premium over the JBL Clip 4 ($60) is $40. The audio quality improvement is real but not transformative — it's a meaningful step up, not a categorical leap.
Who should buy this
The outdoors person who prioritizes audio quality and wants the best compact waterproof speaker available, and is willing to pay the premium for it. If you've been disappointed by tinny or loud-but-distorted speakers, the Wonderboom 3's output quality resolves that.
Who should look elsewhere
Budget outdoor: Tribit StormBox Micro 2 ($50) or JBL Clip 4 ($60). Speakerphone needed: Sony SRS-XB100 ($60). Ultra-compact: JBL Go 3 ($40).
