LG xboom Blast review

Sound

The Blast combines two woofers, separate tweeters and three passive radiators. Its documented amplifier output changes only modestly between mains and battery use. That is useful when moving an established setup away from a socket, although wattage alone cannot establish the volume or bass depth available at the far side of a gathering.

AI Sound adjusts the presentation according to content, while Space Calibration Pro is intended to account for placement. These features provide ways to adapt the speaker to a room or patio. A consistent familiar track and ordinary EQ setting are sensible starting points before deciding whether the automatic adjustments help.

Connectivity

USB-C audio gives the Blast a useful second life beside a compatible computer. The same connector also supports phone charging, so its role depends on the device and connection in use. It should not be treated as a promise of every possible USB function, such as playing files from any thumb drive.

Auracast and Party Link provide group listening options, with dual and multi modes documented. These are worthwhile when another compatible speaker already belongs to the household. For a single speaker, the more immediate benefit is Bluetooth multipoint, which reduces repeated pairing when switching between two sources.

Battery & charging

The thirty-six-hour figure uses Play Time Enhance, no lighting and an 80 dB SPL test level. That mode qualification matters because it changes the sound and energy demand. A full-volume party with lights and a phone drawing power is a different workload.

LG lists charging in three hours or less, depending on operating conditions. The USB-C power output can provide up to 18 watts, useful for keeping the music source alive, but doing so uses the speaker's battery reserve. Charging the phone beforehand leaves more of that reserve for playback.

Design

The top handle suits ordinary lifting, while the side rope handle allows a narrower vertical carrying position. That is helpful when moving through a doorway or between people. The cabinet still needs a stable place to rest and adequate space in a vehicle or storage cupboard.

The stated IP68 test covers freshwater immersion up to one meter for one hour. It is a meaningful protection level, with the usual need to dry the speaker before use or charging. It does not turn salt water, detergents or wet charging into intended operating conditions.

Alternatives

The Stage 501 is the more relevant LG option for karaoke, with microphone and instrument facilities and a cabinet that can be positioned for performance. The Blast prioritizes the outdoor music role and a stronger immersion rating. Choose between them according to whether live inputs or weather exposure drives the purchase.

Verdict

The Blast is a well-equipped option for an outdoor music setup that can accommodate its size. USB-C audio broadens its usefulness at home, and battery operation preserves most of its rated amplifier output. Judge the endurance claim in its stated mode, then decide whether the carrying space is justified.
