Our Verdict

Bose SoundLink Flex (2nd Gen)

LG xboom Grab

The LG xboom Grab and the Bose SoundLink Flex (2nd Gen) are both compact, portable Bluetooth speakers designed with the outdoors in mind. The Bose has a sleeker, more understated design, while the LG takes a funkier approach, with a colorful light strip (which you can turn off if you prefer). They're both IP67 rated for water and dust resistance, so they both suit a park hang or camping trip. They'll both work with your phone's Siri or Google Assistant. The Bose has a slightly more balanced sound out of the box, but the LG is probably the more practical outdoor pick due to its slightly more rugged design and longer battery life. Still, both these speakers serve a similar purpose.
