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 Received as Christmas gift. Already had a Sony that I had been using for a while but the Bose was lighter more powerful and sounded much better so that I could take it with me on my daily walks. Best sound of any I've used.

Rated 5 out of 5 by from I refused to settle for off-brand junk I've been wanting a quality battery powered Bluetooth speaker for a long time.I have a prince's taste on a pauper's budget, so I resisted buying on the low end and just settling for that. I'm so glad that Bose put this product on sale when I could manage the purchase. Since it is a Bose, I expected to be impressed by this product, and I was not disappointed. Maybe next month I can get another one to pair with it for the stereo.

Rated 5 out of 5 by from Durable, portable, and HQ sound. Thank you. No product is really deserving of a perfect rating but I had to give this product 5 stars because it has genuinely raised my standards of what a portable speaker should be... durable build, high quality sound, and a surprisingly deep bass for such a small package. It's comfortable traveling with me even if I slip it in the back pocket of some form fitting jeans and its sound is room filling. Longer battery life is the only improvement I could think of because I want to use this more than the battery will let me half the time and thats not a complaint i just use it entirely too much. Quality product no complaints here at all.

Rated 5 out of 5 by from Excellent sound and design I purchased for my wife because the battery of the mini SoundLink that we bought almost 20 years ago is not lasting much, still exceptional sound.. We use it in the backyard. Excellent sound as all my previous Bose speakers I still have. More loud, clear and detailed sound if I can use the word. Beautiful design and color.

Rated 5 out of 5 by from Big sound for an affordable price. I have been exposed to a few of these from family members and was always impressed with the Big sound from a small speaker! I now have one of my own and am still amazed. Thanks for the great sound.

Rated 5 out of 5 by from Great pairing Much easier to use than gen 1. Automatically pairs with another gen 2 starting with stereo. Sounds seems better in highs and midrange. Both gen 1 and gen 2 sound great much beyond their size. Even good with classical music

Rated 5 out of 5 by from Amazing sound I bought this for Christmas as a gift to myself to use @ Mardi Gras. I am quite pleased!! The sound is amazing. It has the sound of a big speaker and the base is extraordinary

Rated 5 out of 5 by from Big sound in a small package! I’ve purchased 6 of these now as I absolutely love them. They sound amazing, have excellent battery life and provide a satisfied listening experience whether you’re at home, work, hanging out at the pool/beach or enjoying nature on a hiking trail. No complaints! We love the Bose App (Bose Connect) which allows us to pair 2 speakers using party mode. This feature allows us to enjoy the music inside and outside by the pool, and yes, they’re waterproof! No complaints about this or any other Bose product. Oh and the reason I’ve bought 6 is because I love sharing and they make great gifts.

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.
Date published: 2025-01-05
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.
