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.

What owners report

  • Durable, waterproof build that survives drops and water
  • Full 360-degree sound
  • Many owners report years of use

Common complaints

  • App pairing for multiple speakers is unreliable

Questions, answered

Does the UE Boom 3 really float?

Yes, it is designed to float, which makes it ideal for pools. It is IP67 rated as well.

Can I pair two Boom 3 speakers?

Yes, the UE app supports stereo pairing of two Boom 3 units, plus PartyUp pairing with other UE speakers.

Is the Boom 3 good for bass?

Bass is decent but not its strength. If deep bass matters most, the JBL Flip 6 hits harder.
