The LG XBoom Grab carries an IP67 ingress protection rating, classifying it as waterproof and capable of withstanding submersion under defined conditions. Its physical footprint measures 210.82 mm wide with a height and thickness both at 73.66 mm, and a total volume of approximately 1143.87 cm³, putting it in a mid-sized portable category at 680.39 grams. Controls are mounted directly on the device, and a detachable cable is included, though there is no remote control, touch screen, or travel bag in the package. The speaker is covered by a one-year warranty.
The LG XBoom Grab uses a mono speaker configuration without stereo speakers, but it does incorporate a passive radiator to reinforce low-frequency output. A single built-in microphone handles call functionality, though it lacks noise-canceling capability, so voice pickup operates without active background noise suppression. Magnetic shielding is not present in this unit.
The LG XBoom Grab is equipped with a built-in rechargeable battery rated for 20 hours of playback, reaching a full charge in approximately 3 hours via wired connection. A battery level indicator is included to keep track of remaining charge, though the battery is not removable and wireless charging is not supported.
The LG XBoom Grab connects wirelessly via Bluetooth with a maximum range of 10 m and supports multipoint pairing with up to two devices simultaneously. For audio codecs, AAC is supported, while aptX in all its variants, LDAC, and Bluetooth LE Audio are absent. The speaker also features Auracast for broadcast audio sharing, though AirPlay, Chromecast, Wi-Fi, DLNA, and Ethernet are not available. On the physical side, a single USB Type-C port is present, while there is no 3.5 mm audio jack, AUX input, 3.5 mm male connector, external memory slot, microphone input, or NFC pairing support.
The LG XBoom Grab operates wirelessly and supports smartphone remote control, allowing playback management from a paired device. Voice commands are built in for hands-free interaction, and voice prompts provide audio feedback during use. A sleep timer is also included as a convenience feature. Fast pairing, radio reception, and power bank functionality are not supported.
The LG XBoom Grab supports stereo pairing, allowing two compatible units to be paired together to produce a stereo sound configuration.
