The SoundLink Flex Bluetooth Speaker is designed to deliver clear, deep sound that's powerful enough to fill a room, and loud enough for any outdoor adventure. Regardless of orientation, PositionIQ technology optimizes sound quality. The SoundLink Flex features a sleek and attractive design that combines durability, portability and functionality. With its silicone body, powdercoated steel grille and reliable, convenient strap, the SoundLink Flex goes with you wherever you go. Whether you're hiking, camping or paddling or in the shower or on the patio at sunset your music is always with you. With its extremely durable materials, it defies the elements and won't be shaken by drops and bumps. Its convenient loop attaches to a clasp or carabiner so you can hang it almost anywhere. The speaker has also been extensively tested and is IP67 rated. That means it's dustproof and waterproof, and will continue to play music even if dropped in water or left out in the rain. The SoundLink Flex also features long battery life, with up to twelve hours of wireless playback per charge. And for even more immersive sound, pair the SoundLink Flex with another Bose Bluetooth speaker or group it with a Bose Smart Speaker to extend your listening experience from indoors to outdoors. Available in black, white or blue.
