The EVERBOOM delivers loud, 360° sound and rugged durability, making it ideal for outdoor parties. Its long battery life and extensive range are offset by occasional Bluetooth issues and the lack of a wired aux input.

The Bose SoundLink Flex (2nd Gen) is a compact, rugged Bluetooth speaker with IP67 protection, 12 h battery life, and adaptive PositionIQ sound. It adds Bluetooth 5.3, aptX and multipoint pairing while retaining the core acoustic design of the first generation.
