Verdict

The Ultimate Ears MEGABOOM 3 is a rugged, cylindrical portable Bluetooth speaker featuring an IP67 dustproof and waterproof rating, a buoyant design that floats in water, and a drop-proof construction. It delivers immersive 360-degree sound with a maximum audio output level of 90 dBC and a 60 Hz to 20 kHz frequency response range, powered by two 50mm full-range drivers and two 55mm x 86mm passive radiators. Key advantages include an impressive 20-hour battery life, a long 150-foot wireless Bluetooth range, the "Magic Button" for one-touch music streaming control, and the capability to pair with up to 150 compatible Ultimate Ears speakers. On the downside, the speaker lacks a standard 3.5mm auxiliary port for wired connections, relies on an outdated Micro-USB charging port rather than USB-C, lacks an integrated microphone for hands-free speakerphone calls, and can struggle to produce deep, ultra-low sub-bass frequencies.

Ultimate Ears Megaboom 3 Review

The Ultimate Ears Megaboom 3, rated "Good" (1.9) by CHIP, is a highly rugged, water-resistant speaker boasting over 27 hours of battery life, a customizable EQ, and Party-Up multi-speaker pairing. While the sound quality is good, the speaker lacks an AUX input and high-resolution aptX support, with some, albeit efficient, thinness in the bass and limited utility for the new "Magic Button" noted as drawbacks.
