The Bose SLINKFLEXBLK SoundLink Flex Bluetooth speaker is engineered to deliver clear, deep sound that's powerful enough to fill a room and loud enough for outdoor adventures. No matter the orientation, PositionIQ technology optimizes the sound. The SoundLink Flex has a sophisticated, inviting aesthetic and an industrial design that blends durability, portability, and utility. With its silicone body, powder-coated steel grille, and reliable utility loop, SoundLink Flex goes where you go and plays as you play. Listen to music while hiking, camping, or paddleboarding — even while taking a shower or enjoying a sunset on the patio. Its highly durable materials allow it to withstand the elements and mishaps — from drops to shocks. Its utility loop can attach to a clip or carabiner, so you can hang it almost anywhere. And the speaker's been rigorously tested to meet an IP67 rating, which means it's waterproof and dustproof. Dunk it in water or leave it in the rain, and it'll keep on playing. SoundLink Flex also has a long-lasting battery life, offering up to 12 hours of unplugged playtime per charge. For even more immersive sound, pair your Soundlink Flex with another Bose Bluetooth speaker, or connect it to a Bose smart speaker to extend your listening experience from inside the home to outside. Available in Black, White Smoke or Stone Blue.
