Ultimate Ears Boom 4

Ultimate Ears BOOM 4: The Adventure-Ready Speaker for Sound Everywhere

If you’re looking for a Bluetooth speaker that combines ruggedness, style, and premium 360° sound — the Ultimate Ears BOOM 4 is a top-tier choice. Whether you’re chilling at home, heading to a beach picnic, or planning an outdoor adventure, the BOOM 4 is engineered to deliver bold, balanced audio in every direction, no matter where you are.

Immersive 360° Sound, Wherever You Go

One of the standout features of the BOOM 4 is its full 360-degree audio. Thanks to two full-range drivers and dual passive radiators, the sound radiates evenly in every direction. That means no matter where you place the speaker — the music feels consistent and immersive. The tuned drivers produce a pleasing balance of mids and highs, and the passive radiators help reinforce the bass without distortion.
With a maximum sound level of around 85 dBC, it’s loud enough to liven up a small gathering but refined enough not to overwhelm.

Built to Brave the Elements

Durability and portability are core to the BOOM 4’s design. It’s rated IP67 for water and dust resistance — meaning it can be fully immersed in water for a short time and will still survive. On top of that, it’s drop-proof from heights of up to 1.5 metres (about 15 feet), so accidental slips or knocks are well within its tolerance.
A really fun perk: the speaker floats, making it perfect for pool outings, riversides, or beach days.

Long-Lasting Power for Extended Play

The BOOM 4 packs a rechargeable lithium-ion battery that offers up to 15 hours of playtime on a single charge. This gives you ample time for music during picnics, workouts, or daily commutes.
Charging is quick too — thanks to a USB-C port, you can power it up in about 3 hours (with a suitable charger) so you’re not waiting forever between sessions.

Strong, Reliable Connectivity

With a wireless range of up to 45 metres (approximately 147 feet), the BOOM 4 gives you freedom to move around while streaming from your device without worrying about dropouts. Plus, it allows connection from two source devices at once, so you and a friend can take turns playing your favorite playlists.
Using the Ultimate Ears BOOM app, you can also pair multiple compatible speakers (BOOM, MEGABOOM, EPICBOOM, etc.) to amplify your sound through the “PartyUp” feature.

Convenient Music Control with Magic Button

The BOOM 4 features a Magic Button right on the speaker. Tap to play, pause, skip tracks, or use it for one-touch access to playlists set up via your favorite services like Spotify, Amazon Music (Android), or Apple Music (iOS).
It’s a very practical and intuitive way to control your music without constantly returning to your phone.

Customizable Sound with EQ Options

Through the UE BOOM app, you get access to a custom EQ — you can choose from four preset sound modes or tweak settings to suit your tastes.
Whether you prefer more bass for parties, a flatter tone for podcasts, or something in between, the flexibility is there.

Environmentally Conscious Build

Ultimate Ears has made sustainability a priority. Over 52% of the BOOM 4’s plastic components (by weight) come from post-consumer recycled plastic.
This makes it not just a rugged and high-performing speaker, but one that is more gentle on the planet.

Design & Portability

• Size & Weight: The BOOM 4 is compact and lightweight — around 620 g (1.4 lb).

• Build: It has a cylindrical, fabric-wrapped design that’s easy to grip and carry.

• Bungee Loop: There is often a built-in or attached loop/bungee that allows you to tie or hang the speaker on your backpack, bike, or wherever you like, giving it real portability for travel.

Why BOOM 4 Is Ideal for Bangladeshi Consumers

• Climate-ready: Given Bangladesh’s humid and rainy seasons, a waterproof and dust-resistant speaker like the BOOM 4 is especially valuable.

• Outdoor use: Whether for family get-togethers, rooftop music sessions, or trips to the countryside, the BOOM 4’s ruggedness makes it perfect for both indoor and outdoor settings.

• Daily flexibility: Long battery life and portability mean you can use it throughout the day — from morning chores to evening get-togethers — without constantly recharging.

• Sustainable choice: Environmentally conscious consumers will appreciate the recycled plastic build.
