Ultimate Ears Boom 3 Review (2026)
Ultimate Ears Boom 3 review: 360 sound, waterproofing, battery, and value assessed from specs and published reviews.
Ultimate Ears Boom 3
360-degree sound that floats.
Our verdict
The Boom 3's party trick is genuine: 360-degree sound that fills a space evenly no matter where you put it, plus an IP67 rating and a design that floats. Bass is polite rather than powerful and charging is still micro-USB, but for social listening it is one of the most likeable speakers you can buy.
What we like
- True 360-degree sound fills spaces evenly
- IP67 rating and it floats in water
- 15-hour battery outlasts most rivals
What to watch out for
- Bass is polite rather than powerful
- Older micro-USB charging port
- App features are nice but nonessential
Who it is for
Hosts and groups who want even, room-filling sound for patios, pools, and campsites.
Design and durability
The cylindrical design with its two-tone fabric looks great and is built for abuse: IP67 sealing, drop-tested construction, and it floats. The one dated element is the micro-USB charging port.
Sound performance
360-degree drivers spread sound evenly, which matters more than raw volume for group settings. Bass is present but restrained; this is a clarity-first tuning rather than a bass cannon.
Battery and value
Fifteen hours is excellent and honestly rated. Value is strong, especially as the Boom 3 frequently discounts below its launch positioning.

Can I pair two Boom 3 speakers?
