About
What it is.
Cylindrical rather than boxy, the Megaboom 4 is built by Ultimate Ears (a Logitech brand) around two full-range drivers paired with a set of passive radiators, giving it 360-degree sound and low-end output that's unusual for something this size. Bluetooth connects it to phones and tablets, with the option to pair multiple Megaboom or compatible UE units through PartyUp for shared playback across rooms or outdoor spaces.
The body shrugs off dust, drops, and submersion, and floats if it ends up in a pool. A single Magic Button on top handles playback and pairing, and the BOOM app adds equalizer control and preset access. It's suited to people who want a speaker they can grab, pair, and forget about — no menus, no fragility, no second-guessing the brand.
The verdict
The Megaboom 4 delivers rich sound and powerful bass in a durable, water-resistant package that buyers consistently praise, though battery life and charging reliability remain contentious enough to give some owners pause. At $180–$211, it suits anyone who prioritizes a trusted brand and proven durability over perfect longevity between charges.

AI summary of 5 reviews · as of Aug 2026
Reviewers agree the Megaboom 4 is a rugged, loud, all-direction speaker with strong bass and long battery life, though the upgrade over its predecessor is mostly the switch to USB-C rather than a real sound overhaul.

- Long battery life, around 20 hours per charge

Frequently asked
What buyers want to know.
What does the Megaboom 4 sound like?
Buyers rate sound quality and bass at 4.8 out of 5, calling it rich and powerful for its size. The cylindrical design pairs two full-range drivers with passive radiators to deliver 360-degree sound and low-end output that stands out in a portable speaker this compact.
How long does the battery actually last?
Battery performance is the main weakness—buyers rate it 2.5 out of 5. One owner reported roughly 2 hours of continuous playback on a full charge, sometimes less. This is a sharp drop from earlier Megaboom models and a significant source of divided opinion among current owners.
Are there charging issues I should know about?
Yes. Buyers report that the battery doesn't always charge reliably when plugged in, which has become a pain point for some owners. Combined with short battery life, this is the most contentious aspect of the product.
Is it durable and waterproof?
Yes. Buyers rate durability and water resistance at 4.7 out of 5. The body shrugs off dust, drops, and full submersion, and the speaker floats if it ends up in a pool. Owners describe it as tough gear built to travel.
How easy is it to pair and use?
Very. Buyers rate ease of connectivity at 4.8 out of 5. A single Magic Button handles pairing and playback, so you can grab the speaker, connect it via Bluetooth to your phone, and go—no menus or setup required.
Who should buy this speaker?
It fits anyone who wants a proven, trusted portable speaker from an established brand and doesn't want to fuss with setup or worry about durability on the road. It suits you if you value strong sound and premium feel over maximum battery life, or if you plan to use the speaker near a power source. If you need a speake…
