The verdict
Buy for simple outdoor audio, not maximum output
This is a cheerful, low-maintenance gift for someone who wants music in the shower, at the cottage or beside a pool without nursing fragile electronics. Its controls and floating construction are more important than sonic ambition. Choose something larger for a busy backyard party, deeper bass or longer events, and choose another speaker if calls, AUX input, Wi-Fi or app EQ matter.
Why it works
- ✓ IP67 construction is dust-tight, survives specified immersion and floats for easier retrieval
- ✓ Small 418 g body, carry loop and even sound dispersion make it easy to place and pack
- ✓ USB-C, a 14-hour manufacturer claim, Outdoor Boost and Podcast mode keep operation simple
Tradeoffs
- × A speaker this small cannot produce deep low bass or cleanly fill a large, noisy gathering
- × There is no microphone, speakerphone, voice assistant, AUX input, Wi-Fi or supported app EQ
- × Outdoor Boost emphasizes projection rather than natural sound, and the box omits a USB-C cable
Confirm the fourth generation before gifting
- Identity: the listing must say WONDERBOOM 4. USB-C and the Podcast EQ mode distinguish it from the visually similar micro-USB WONDERBOOM 3.
- Water: IP67 testing covers fresh-water immersion to defined limits; rinse after pool or salt exposure and dry the USB-C port before charging.
- Pairing: two compatible WONDERBOOM speakers can play together, with stereo available for supported pairings. This is not the app-driven PartyUp system used by larger UE models.
- Expectations: 360-degree coverage is convenient around a table, but it does not mean spatial audio, deep bass or room-filling party output.
The Canadian box is unusually minimal
| Decision | Included | Not included |
|---|---|---|
| Core kit | WONDERBOOM 4 with integrated carry loop and documentation | Carabiner, protective case or second speaker |
| Charging | USB-C charging port on the speaker | USB-C cable or wall adaptor, according to the official box list |
Wonderboom 4, Wonderboom 3 or a larger speaker?
| Decision | Choose Wonderboom 4 | Choose the alternative |
|---|---|---|
| First speaker | USB-C convenience, waterproof portability and simple controls are the priorities | Choose JBL Clip 5 when an integrated carabiner and app EQ matter more |
| Already owns 3 | USB-C removes a real cable annoyance and Podcast mode will be used | Keep WONDERBOOM 3 when micro-USB is tolerable; sound and design changed little |
| Party scale | One or two listeners need background music they can carry anywhere | Choose JBL Charge 6, UE BOOM 4 or larger when volume and bass matter |
Quick answers before gifting
Does Wonderboom 4 actually float?
Yes, Ultimate Ears says it floats and independent reviewers verified the pool-friendly design. Floating aids retrieval; it does not make the charging port usable while wet.
Is the battery really 14 hours?
Fourteen hours is the manufacturer claim and varies with volume, modes and conditions. RTINGS measured roughly 13 hours, close enough for a day outing rather than an entire weekend.
Can it answer phone calls?
No. It has no microphone or speakerphone function, so calls stay on the connected phone or another audio device.
Can two Wonderboom 4 speakers play stereo?
Yes. Pair two compatible units using the hardware controls for louder Party mode or left-right stereo; check UE's current compatibility guidance before mixing generations.
Does it include a charging cable?
The official current Canadian box list does not include one. Plan to supply a USB-C cable and compatible charger if the recipient does not already have them.
