Bose SoundLink Flex (2nd Gen) Review

The Bose SoundLink Flex (2nd Gen) lives up to the brand’s reputation for delivering premium audio in compact form. Whether indoors or outdoors, the sound remains consistent and high-quality thanks to the PositionIQ feature.

The rugged construction is where this speaker truly shines. Whether it’s being tossed in a bag, splashed poolside, or used during a dusty hike, the SoundLink Flex handles the abuse with ease. The silicone body resists scratches and scuffs, while the waterproof design means you don’t have to baby it during use.

Pairing two units together for stereo sound works flawlessly, and the speaker maintains clarity and power when pushed to higher volumes. Whether you’re hosting a BBQ or just relaxing in the park, the Flex 2nd Gen proves it can handle both calm and chaos.
