• Durable construction: An IP67 rating and a siliconewrapped body mean the speaker resists water, dust, drops, and shocks for reliable outdoor use.
• Bluetooth 5.3 and multipoint: Modern Bluetooth ensures a steady connection up to about 30 ft and the ability to pair multiple devices for easy switching.
• Stereo pairing: Two compatible Bose speakers can be linked for Stereo or Party Mode to expand the soundstage when needed.
