Ultimate Ears MEGABOOM 4: problems, parts and running costs
Checked: 2026-10-05
Summary
The MEGABOOM 4 is a large, bass-forward 360° Bluetooth speaker with IP67 sealing and a floatable body, and its main cautions are its size — 0.935 kg and roughly twice as tall as it is wide, which a hands-on reviewer found impractical for a backpack — and lab sound quality that Consumer Reports rated middling, with distortion and a two-dimensional soundfield. Battery life is up to 20 hours claimed, with no measured runtime. It suits a fixed poolside, patio or in-room spot rather than travel.
Common problems and fixes
- Too bulky to carry — at 22.5 x 8.7 x 8.7 cm and 0.935 kg the speaker is a tall cylinder a hands-on reviewer could not see using anywhere but home, and he swapped it for a smaller Anker Soundcore before a trip; buy it to leave by the pool, on a patio or in a room. [2]
- Lab sound quality is middling — Consumer Reports found distortion and other audio issues, bass with decent impact but lacking deep bass and a touch boomy, a grainy, hazy and slightly nasal midrange, subdued and slightly sizzly treble, and a two-dimensional soundfield; What’s The Best, by contrast, praised clarity and bass. The two disagree and neither publishes raw measurements. [2][3]
- Battery is a claim, not a measurement — the up-to-20-hour figure carries a manufacturer footnote that high volume and bass boost shorten it, and no source read measured actual runtime; charging takes about 3 hours. [1][2][3]
- No microphone and no wired inputs — there is no speakerphone and no built-in mic, no analog, optical or headphone input, and firmware cannot be updated. [2][3]
- Battery is not documented as user-replaceable — no user-replaceable part is documented and no battery-replacement cost is established. [2][3]
- Sealed charging port needs care — the USB-C port sits behind a rubber-sealed flap that also maintains the waterproofing, so keep it closed; IP67 covers dust and immersion to 1 m for 30 minutes, not drop resistance. [1][2]
- Driver configuration is unverified — the published 2 x 50 mm full-range plus 2 x 55 x 86 mm passive radiator line matches the older MEGABOOM 3, while a retailer describes a larger woofer, so treat it as unconfirmed for this model. [1][4]
Parts and consumables
No replaceable parts or consumables reported. No user-replaceable part is documented, the battery is not sold as a replacement, and the only routine care is keeping the sealed USB-C flap closed. [2][3]
Yearly running cost
Close to zero beyond charging. There are no filters, subscriptions or firmware costs, no battery-replacement path is documented, and a USB charging cable and Quick Start are included. The main ownership question is whether the size fits your use; if it does not, the money is better spent on a smaller speaker. [1][2][3]
When it is a good buy
Ultimate Ears direct listed the MEGABOOM 4 at $199.99 in Cobalt Blue with free shipping and 30-day free returns (October 2026), while Consumer Reports showed a US street reference from $149.99. At $199.99 the case rests on volume, bass, IP67 wet use and app EQ rather than on measured sound quality, which the lab rated middling. Below roughly $150 the size and weight are hard to justify against smaller speakers. The named alternative is a smaller Anker Soundcore, which the hands-on reviewer chose for travel; buy the MEGABOOM 4 instead only when it can stay at a pool, on a patio or in one room. [1][2][3]
