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.

Rated 5 out of 5 by from Multiple applications for usage I bought these speakers for their portability. I can use them in the back yard when BBQ or take them camping or just one when riding my bike. They sound really nice and I'm very happy with them. Using your phone to control volume and song selections is easy and convenient. I bought two from Bose direct - (better price) and they pair to make stereo.

Rated 5 out of 5 by from Perfect marriage of color and sound Admittedly, I bought this speaker in Petal Pink, Sandstone, and Sage. The sound quality is amazing from this compact speaker and it's easy to pair with my phone. You can also pair multiple speakers to the same device. I had the older black model but these colors really brighten up a room. I think the battery life is longer too (without the charger tray too!).

Rated 5 out of 5 by from Bose SoundLink Flex Portable is Amazing 👏 The SoundLink Flex Portable is another example of the tireless innovation of Bose. This small speaker system packs an amazing base punch with incredible sound quality. The smaller products kept getting better since the introduction of the little speakers back in 1998. Not too long after came the Wave Radio and other Bose products built with small speakers continued to follow. Keep designing stellar products and I am anxious to see (and hear) what comes next. Cheers!

Rated 5 out of 5 by from Great for around the pool! I am very happy with my purchase. Shipping was fast. I purchased this so we could hear TV and/or music out on our lanai.Our entire wall in living room is glass sliders so we can see the tv while sitting outside, but were unable to hear it. This speaker works perfectly. The speaker is water proof so it is perfect around our pool or at the beach. The sound of this small speaker is mind blowing. I love that you can switch bluetooth device input with a push of a button.

Rated 5 out of 5 by from Best Sound Ever for Bluetooth Portable Speakers Best bluetooth speaker for sound. Great bass, great projection. I wish it were lighter so it would be better suited for travel. I didn't see another BOSE speaker any lighter.

Rated 5 out of 5 by from Soundlink FLEX portable speaker We owned a Bose portable speaker, but chose to buy the Flex Speaker because it's smaller and will be easier to take on the plane with us when we travel. As with ALL BOSE speakers the sound is PHENOMENAL. and we got it for a GREAT price.
