Sound that takes you places.
Hit the road in hi-fi with the surprisingly powerful performance of SoundLink Flex. It’s clear, balanced, high-fidelity audio and deep bass you wouldn’t expect from a speaker this easy to take with you. Want higher highs or lower lows? Tweak the sound with Adjustable EQ in the Bose app.
Perfectly portable, with battery life to match.
Pack your playlist — no problem. The speaker is small enough to fit in your hand, throw in your pack, or clip to the outside with the durable utility loop. And you can focus on the fun with up to 12 hours of battery life* — enough for even the most adventurous of tastes.
Toss it. Drop it. It’s all good.
Rated IP67, SoundLink Flex is designed to take on all your adventures. It’s dust and waterproof, and it floats — so a quick dip in the pool won’t sink your sound. The speaker’s durable, silicone-wrapped body also withstands drops, crushing, shocks, and rust.
Stay connected with advanced Bluetooth 5.3.
Advanced Bluetooth 5.3 offers a strong, continuous connection to your device from up to 30 feet away. And multi-point connections keep the speaker paired to multiple devices at once, making it easy to share DJ duties with a friend.
Stereo on the go.
When you need more sound, press the shortcut button on the speaker and on another SoundLink Flex (2nd Gen) or SoundLink Max Portable Speaker to pair the two (sold separately). Once linked, you can choose from Stereo Mode to separate left and right channels or press the shortcut button again to switch to Party Mode for even bigger, bolder sound.
Plays from any position.
Stand it up, lay it back, hang it upside down — SoundLink Flex will always give you the best sound. Bose PositionIQ technology senses the speaker’s orientation and automatically adjusts its performance accordingly.
Stay in touch when you head out.
Make and take calls when you’re on the go with the speaker’s built-in microphone. Or use it to access your device’s native voice assistant when your phone is out of reach.
