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 Great product. I bought this for my grown-up son for Christmas 2024. The sound is excellent as Bose always is. I am thinking about buying one to put on my fishing boat. Great product.

Rated 5 out of 5 by from Great quality! Absolutely love this speaker, love the sound quality and clarity this speaker. My first speaker I have bought after doing some homework, decided on this gem. Would recommend to everyone that is looking for one.

Rated 5 out of 5 by from Great Sound and Portability - Just needs buttons! I enjoy this speaker. I like that it's easy to bring with you places. I think that it's easy to use and has great sound. I'm disabled and it's not too heavy, which is definitely a plus. You can also fit it in many bags or use a carabiner to attach it to one. The one downside is that there are not real buttons. It's a bit of a rubbery sleeve on it and there are buttons somewhere underneath. It can be a bit hard if you have vision impairments or tactile issues. If the future generations could be updated to include actual buttons, I think that would be a good benefit for those of us who need them.

Rated 5 out of 5 by from Unbelievable Power and Sound Bought this FLEX 2 speaker to pair with my IPAD as I enjoy listening to Pandora. I love everything about this speaker. My husband was a professional musician and he too was so impressed with the clarity and quality of this speaker. Plus, you don’t have to keep your iPad on as the speaker takes over the second you put the speaker on. With the size and power of this speaker it is to easy to take it from room to room as I do when cleaning my house. I would not hesitate to recommend this little powerhouse. You will not be disappointed believe me. I am a huge fan of Bose products and this little gem certainly did not disappoint me.

Rated 5 out of 5 by from Wonderful Speaker I was surprised by the sound of this speaker. It sounds wonderful. It can really get loud too. But we didn't buy it because could get loud. Quality of sound is just great. Surprisingly strong bass as well. I bought it for my wife who like to craft, sew and do other projects. She has been using her iPhone to play music. This is way better and she loves it.

Rated 5 out of 5 by from Powerful Sound in a Compact Package! I’m absolutely loving the Bose SoundLink Flex Portable Speaker! The sound quality is exceptional for its size – clear, rich, and surprisingly deep bass. It's perfect for both indoor and outdoor use. The build is rugged making it great for beach days or hiking trips. Battery life lasts a very long time, and the Bluetooth connection is reliable. It’s compact yet powerful, and I appreciate the sleek design. Overall, it's the perfect speaker for anyone who wants portability without compromising on sound quality. You just can’t go wrong with Bose. Highly recommend!

Rated 5 out of 5 by from HUGE SOUND IN A SMALL PACKAGE I was looking for a wireless speaker to use on my motorcycle. I’m a huge Bose fan so ordered this Flex speaker. I was amazed by the HUGE sound this little speaker puts out! Deep base, and clear mid and high range. It will certainly overcome wind noise at highway speeds! Very impressive unit. I may buy a second to pair up at home!
