The 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. 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 like 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 play time 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.Astonishing sound. Wherever life takes you.The SoundLink Flex Bluetooth speaker plays astonishing sound wherever you are. The sound is crisp, clear, and free of distortions, so you can hear each instrument and nuances in the vocals. The treble and bass are balanced, allowing you to hear every pitch. Its sound immerses you and offers a stronger, deeper connection to your music. Loud enough to fill a room, it can play over ambient noise while you're entertaining at home. Its powerful bass can boom and project music that energizes and makes you rock your head.Tilt it. Flip it. Hang it. Always incredible sound.It doesn't matter whether SoundLink Flex is upright on the kitchen counter, hanging from a backpack, or flat on its back at the beach. Its PositionIQ technology automatically detects its orientation and ensures natural, lifelike sound in any position. You don't have to do a thing. Tilt it. Flip it. Hang it. No matter the orientation, PositionIQ ensures optimal sound.Innovative technology for an inspired performance.A product of Bose's state-of-the-art engineering, SoundLink Flex is packed with exclusive technologies. Its innovative transducer is custom-designed to deliver the clearest possible sound and strong, deep bass you can feel in your chest. The speaker's digital signal processing (DSP) technologies, proprietary code, and custom algorithms all work together to ensure optimal sound quality wherever you are.A rugged exterior that withstands the elements.With its powder-coated steel grille and silicone exterior, the SoundLink Flex Bluetooth speaker was purpose-built with durable materials, making it adventure-ready. Its tough exterior can withstand almost any mishap, like a fall to the floor. The grille's thick coat of powder gives the speaker a rugged texture that can withstand whatever your day throws at it. The powder coat won't peel or flake, and it's resistant to corrosion and UV light. Premium materials hug the exterior and provide a tight seal around sensitive electronics, protecting them from water, dust and debris, so nothing gets between you and your sound.Elegant design that sets you apart from the crowd.With an inviting, sophisticated aesthetic, SoundLink Flex stands out wherever it plays. It comes in three beautiful colors - Black, White Smoke, or Stone Blue - that can bring any room or space alive. With its unique ergonomic design, the wireless speaker is easy to hold and feels good in your hand wherever you grab it. It's easy to grip, even if it's wet. Its compact size allows it to fit in a small space or bag. It was designed to maintain a secure stance while playing in the upright position.Hang it using the utility loop.With its rugged utility loop, you can secure SoundLink Flex to almost anything. Attach the portable speaker's loop to a carabiner and hang it from a beach chair, or secure it to a strap on your backpack on a hike. You can even use the utility loop to hold the speaker with your finger. Designed to resist twisting, the loop won't spin or turn when it's hanging.Waterproof & dustproof.Rigorously tested to meet an IP67 rating, the SoundLink Flex is waterproof. Dunk it in water, and it'll keep on playing. If it's dirty, rinse it off with water. It even floats, so it won't sink to the ocean floor if it falls off your paddleboard. The speaker is also protected against dust, so you don't need to worry if it gets sandy at the beach. To ensure further protection from water, dust and debris, acoustic components, such as the transducer and passive radiators, which sit underneath the steel grille, were built with rugged, waterproof materials. These components are sealed tightly to the speaker's housing, keeping out water and dust without disrupting your sound.A long-lasting battery that goes the distance.The rechargeable lithium-ion battery for SoundLink Flex offers up to 12 hours of unplugged play time - enough to last throughout the day.Power-up with convenient charging.To charge your SoundLink Flex, connect the charging cord (USB-C to USB-A) to a USB port on your computer or to an outlet using a USB power supply (not included).
