Portable Bluetooth Speaker LG xboom Grab Core by will.i.am - Rugged

In this review the LG xboom Grab Core by will.i.am is evaluated as a portable Bluetooth speaker aimed at active users who want bold sound on the move. The bottom line: this speaker is best for bikers, hikers and outdoor athletes who need a rugged, waterproof speaker with strong low-end and long battery life; its standout feature is sound tuned by will.i.am and a Peerless 16mm dome tweeter plus racetrack woofer for surprisingly full low-frequency response. The review finds it a durable, well-balanced option that favors outdoor reliability over compact pocketability.

Key Features

• Artist-tuned audio: Sound signatures and presets developed with will.i.am aim to deliver dynamic, immersive playback that highlights vocals and bass for casual and upbeat tracks.
• Durable construction: The unit passed seven MIL-STD-810H tests to resist rain, shock, dust, vibration, salt fog and immersion, so it holds up during rough outdoor use.
• IP67 protection: Dust and water resistance means the speaker can survive beach days, rain showers and accidental immersion without stopping the music.
• Long battery life: Up to 19 hours of playback on a single charge keeps music playing through long rides or day hikes without frequent recharging.
• Portable design: Adjustable carrying straps and an easy-to-grab shape make it simple to sling the speaker on a pack, bike, or handle while moving.
• Auracast sharing: Wireless multi-receiver streaming lets one source send audio to multiple compatible earbuds or speakers for group listening at events or gatherings.

Who It's For

The LG xboom Grab Core is aimed at outdoor enthusiasts and athletes who prioritize durability and loud, full sound while on the move. Cyclists, trail runners, hikers and small-group outdoor gatherings will benefit from the IP67 rating, military-grade testing and the long battery life that keeps playlists going through a full day outdoors.

Those who want an ultra-compact speaker for pocket carry, or audiophiles seeking studio-accurate flat response, should look elsewhere; this model favors ruggedness and tuned, impactful sound over tiny size or fully neutral reproduction.

Pros & Cons

Pros

• Robust, military-tested construction that stands up to rain, dust and shock.
• Full, dynamic sound with notable low-end for a portable speaker thanks to the racetrack woofer and Peerless tweeter.

Cons

• Bulky compared with ultraportable speakers, so it is less convenient for tight pack space.
