## Before you buy

- The listing gives conflicting audio details: it names Stereo output in one field but lists 5.1 channels elsewhere, which does not establish a surround setup. Its generic battery-capacity field also says “15 hours,” a time rather than a capacity unit. IP67, floating, drop protection and 15-hour runtime are manufacturer claims, not independently confirmed performance.

## A good fit for

- Listeners wanting a compact Bluetooth speaker for travel, casual outdoor use or tabletop listening.
- Buyers who value a water-resistant design claim and the option to group compatible Ultimate Ears speakers.

## Less suited to

- Buyers who require a charging cable in the box.
- Listeners seeking a clearly specified multichannel home-theater system or high-output party speaker.

## Customer feedback

Customer feedback often highlights sound quality, Bluetooth connectivity and portability, with the small footprint relevant to travel and tabletop use. Battery life, durability, charging and value draw mixed reactions. That matters alongside the listed 15-hour runtime and USB-C charging claim, particularly because the cable is not included. Aggregate ratings lean positive overall but do not resolve these differing experiences.
- Positive themes: Customers highlight sound quality, connectivity and portability.
- Mixed feedback: Battery life, durability, charging capability and value receive mixed feedback.

## Frequently asked questions

### Does the Boom 4 include a USB-C charging cable?
No. The listing says it charges via USB-C and specifies that the cable is not included.
### How long is the listed battery life?
The listing claims 15 hours on a charge. Customer feedback is mixed on battery life, so actual results may differ.
### Can it pair with other Ultimate Ears speakers?
The PartyUp feature is listed for select BOOM, MEGABOOM, EVERBOOM, EPICBOOM and HYPERBOOM speakers. The listing excludes WONDERBOOM and MINIROLL.
### Is this a 5.1-channel speaker?
The listing is inconsistent: one specification says Stereo, while another says 5.1. Check the selected product details if channel configuration matters.
