Why it makes sense

This model focuses on outdoor reliability, offering IP68 waterproof and dustproof protection, and a floating playback design that resists sinking and keeps sound forward when on water. The housing is five times saltwater-resistant according to the manufacturer and has been drop-tested from 3.28 ft 1 m, so it shrugs off spray and spills. BassUp 2.0 and DSP tuning boost low frequencies down to about 56Hz, so the compact form still delivers satisfying impact at casual volumes.

Best use cases

Take the Boom 3i on kayaking trips, poolside hangs, fishing outings, or camping. It includes TWS pairing for stereo setups, Bluetooth 5.3 for reliable wireless connection, and a detachable strap for hands-free carry. Note that heavy audiophile listening sessions will still expose the limits of a compact speaker, but for outdoor activities this model offers a solid blend of power, resilience, and convenience.

Getting the most from it

You’ll appreciate it if you need a portable speaker that handles water and salt without fuss. Use the companion app to access the voice amplifier, emergency alarm, and Buzz Clean features, and pair two units for wider sound. Keep in mind that battery life varies with volume and feature use, so plan charging for extended outings.
