Not what I expected
I was expecting better from this. Not much bass at all and sound quality is not the best. Bought one from other brand (S__Y) which is of similar size and price but beats it in every aspect. Disappointed, especially considering its price.

Ultimate portable sound!
Love it so much! After my son brought me my own I ended up buying one as a gift for a friend who kept borrowing mine they loved it so much. So great to take anywhere for music on the go!

Things to consider
Its compact size is great for portability, but larger premium speakers usually offer stronger bass depth and higher maximum output for bigger spaces.
Portability rating
9/10 - Compact, lightweight at 0.62 kg and easy to carry for travel or outdoor use.
Outdoor suitability
Excellent for outdoor use thanks to its IP67 waterproof and dust-proof design, floatable build and durable portable form.
Battery endurance rating
8/10 - Up to 15 hours of playback is strong for day trips and casual parties.
Audio quality score
7.8/10 - Clear, balanced 360-degree sound with accurate bass, but not as powerful or deep as larger premium speakers.
Multi-device compatibility
Works well with Bluetooth audio devices and can link with compatible Ultimate Ears speakers through Party Up.
Key benefits
- 360-degree sound: Helps music carry evenly around the speaker so people can enjoy similar sound from different angles.
- Up to 15-hour battery life: Supports extended listening on a single charge for day trips, gatherings or long afternoons outdoors.
- IP67 waterproof and dust-proof design: Better suited to poolside, beach and outdoor use where splashes, rain or dust are a concern.
- Floatable build: Easier to retrieve if dropped in water, making it more practical for boating or pool use.
- 45 m Bluetooth range: Gives you more flexibility to place the speaker away from your phone or tablet in open areas.
- 0.62 kg weight: Lightweight enough to slip into a backpack or travel bag for everyday portability.
- Party Up speaker linking: Lets you connect with compatible Ultimate Ears speakers for wider coverage at group events.
- Four preset EQ modes: Makes it easier to tailor the sound profile to different music styles without extra complexity.
Q: Is it loud enough for a backyard picnic or camping?
A: Yes, for small to medium gatherings. Ultimate Ears Boom 4 reaches 85dBC, which is enough for casual outdoor listening, but its compact size means it is not the right pick for very large spaces or for buyers chasing heavier bass.
Q: Can I link two Boom 4 speakers together?
A: Yes. UE Boom 4 supports Party Up, so it can link with compatible Ultimate Ears speakers for broader sound coverage. It is meant for compatible UE models, not for pairing with Bluetooth speakers from any brand.
Q: Will UE Boom 4 connect easily to my phone or tablet?
A: Yes. UE Boom 4 pairs over Bluetooth with phones and tablets that support Bluetooth audio. Its 45m range gives flexible placement in open areas, though walls and wireless interference can reduce that distance indoors.
Q: How far can my phone be from the speaker?
A: Ultimate Ears Boom 4 supports a 45m Bluetooth range in open areas, which helps when the speaker is set away from your phone. Indoors, walls, furniture and other wireless devices can reduce that range before audio drops out.
Q: Does the Boom 4 battery swap out when it wears down?
A: No. Ultimate Ears Boom 4 uses a built-in rechargeable lithium-ion battery rather than a quick-swap pack. If easy battery replacement matters, treat this as an internal-battery speaker instead of a field-serviceable design.
Q: Can I use Boom 4 for hands-free calls?
A: This model is listed as a portable Bluetooth speaker for music playback. A built-in speakerphone or call microphone is not listed, so it is better suited to streaming audio than to taking hands-free calls directly through the speaker.
