Multipoint is a Bluetooth technology that allows your SoundLink Flex (2nd Gen) to maintain a connection to two paired source devices at the same time. Your speaker will seamlessly transition between the two devices, so you’re always connected to the active source device.
Shortcuts allow you to configure settings for the programmable shortcut button on SoundLink Flex (2nd Gen). You can manage your shortcut in the Bose App. Out of the box, the factory default shortcut is set to linking, allowing you to use the button to link two compatible Bose speakers without the app.
You can change your shortcut button to be connected to your Spotify account to begin music at the press of a button, access your Voice Assistant, or other options that may become available with future firmware updates through the Bose App.
Yes. Using Bose SimpleSync technology, you can connect to your SoundLink Flex (2nd Gen) from a SimpleSync-enabled Bose smart soundbar or Bose smart speaker to extend the reach of your listening to other places in the vicinity, such as an adjacent room. You can manage SimpleSync in the Bose App.
Yes, when there is an incoming call, pressing the play/pause button will answer the call and double pressing the play/pause button will decline a call. Double press the play/pause button while in a call to end it.
Yes, SoundLink Flex (2nd Gen) floats, but is not designed to be used while in water. SoundLink Flex (2nd Gen) is designed to withstand accidental drops in water for up to 30 minutes. If SoundLink Flex (2nd Gen) is directly exposed to salt or chlorinated water, rinse with fresh water and allow to dry thoroughly before use.
If debris gets into the charging port or other parts of SoundLink Flex (2nd Gen), gently rinse with fresh water or compressed air. Be sure charging ports are thoroughly dry before charging. For the larger exterior surfaces, wipe clean with a soft cloth. Avoid using cleaning detergents and let the speaker dry completely before operating.
Owner’s guide
Sound that takes you places
Add music to any adventure and go further. Just press play.
Hit the road in hi-fi
Bold sound for big moves
High-fidelity audio is crisp and nuanced with surprisingly deep bass you can feel. Want higher highs and lower lows? There’s Adjustable EQ in the Bose app.
More speakers. Bigger sound. Better times.
Amp up the adventure and pair two compatible Bose speakers. There’s Stereo Mode for left and right channels and Party Mode to make any hangout epic. Just hit the shortcut button on each speaker.
Plays from any position
Stand it up, lay it back, hang it upside down — you’ll always get the best sound. PositionIQ technology automatically senses the speaker’s orientation and optimizes its audio to bring extra oomph to any moment.
Built to get you where you’re going
A little water won’t sink your sound. And it’s durable, too — so no worries if you drop it when you drop the beat.
Sea. Sand. Doesn’t matter.
An IP67 rating means this dust and waterproof speaker can go almost anywhere. It even floats.
Toss it. Drop it.
It’s all good. The silicone-wrapped body is drop, shock, and rust-resistant.
