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 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, the transducer and passive radiators underneath the steel grille are 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). The charging port is on the opposite side of the utility loop, staying out of the way in any position.
Make and answer phone calls.
With a built-in microphone, you can receive and make phone calls through SoundLink Flex. The exceptional sound quality allows you to hear whomever you’re talking to with clarity.
Easy-to-use, simple to play.
With an intuitive user interface, the SoundLink Flex Bluetooth® speaker is simple to use. The 5 mechanical buttons — power, volume down, multifunction, volume up, and Bluetooth — are uncluttered and accessible whether the speaker is upright, flat, or hanging.
Easy connecting for smooth listening.
The SoundLink Flex Bluetooth® speaker connects to your phone, tablet, or other Bluetooth devices within a wireless range of about 30 feet. Voice prompts talk you through Bluetooth pairing. The speaker remembers up to 8 most recently used devices.
One app for complete control.
Through the Bose Connect app, you can unlock product features, personalize your settings, and get tips. The app automatically updates your SoundLink Flex with the latest software.
Siri & Google Assistant voice commands.
If your phone isn’t nearby, press and hold the multifunction button on SoundLink Flex to access your phone’s native Siri or Google Assistant voice input.
Pair Bose speakers for even more immersive sound.
Whether you’re hosting a party at home or enjoying the outdoors with friends, you can pair your SoundLink Flex with another Bose Bluetooth speaker for louder, even more immersive sound. Pairing is simple through the Bose Connect app, or you can pair manually. Pairing works anywhere, even away from home. You can also pair your SoundLink Flex with select Bose smart speakers and Bose smart soundbars. Use the Bose Music app to pair your SoundLink Flex with compatible Bose smart speakers and smart soundbars and play them all in sync at home — and beyond. The connected devices must stay within the typical Bluetooth wireless range (30 feet) of each other to remain connected. Walls and construction materials may affect reception.
Engineered to withstand the limits.
To ensure the SoundLink Flex Bluetooth® speaker could go wherever you go, it was subjected to hundreds of hours of rigorous testing in conditions far more extreme than we would recommend for you to attempt. Water tests, heat and cold tests, drop tests. Rigorous testing proved that SoundLink Flex is ultra-portable, highly versatile and rugged enough for all your adventures.
