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.

Ratings and Reviews

Rated 5 out of 5 by from Small But Mighty My speakers arrived just before my trip overseas, and I was able to use it extensively throughout my trip. It is the perfect size for taking around without taking up too much space. I can’t say enough about the battery life. I was able to start and end my day with continuous music without having to charge it, which was convenient and a plus. For such a small device it holds its own with the sound quality. The thing that I disliked about small speakers were the fact that it couldn’t handle high volumes, and the sound would get very distorted and muffled. With these speakers, whether I was listening inside in my hotel room, or sitting out by the hot tub, I was able to get great acoustics and bass regardless of what genre I was listening to. The app made it incredibly easy to adjust the settings to what I was listening to. Not to mention it has a very impressive Bluetooth range. Left my phone away from the speakers multiple times and not once did I have to deal with my music cutting out. This was a lifesaver for my trip. With such a small form factor I didn’t have to worry about it taking up too much space. With the sound quality and durability these speakers provide without breaking the bank, I can’t recommend these enough. Might have to grab another one in the future so that I can link them to take advantage of the stereo sound.

Rated 5 out of 5 by from Big sound, small & light package An excellent portable speaker that packs way more sound than you'd expect for its size. This isn't the smallest or lightest Bluetooth speaker out there, but it is small and light enough to truly be on-the-go friendly. I enjoy photography, so I'm already lugging around gear and don't want a big, heavy speaker to add to the mix. It doesn't add much to your backpack or luggage, so you'll be more tempted to bring it with you than, say, the SoundLink Max, which I also have. While the Max is demonstrably better and more powerful, the sheer size and weight makes you think twice about bringing it anywhere. The occasion must call for it. This speaker is often a no-brainer to toss in your bag. Surprisingly, it does have speakerphone support, unlike the Max, which is nice to see. Thanks to no WiFi or "smarts", battery life is also very good. It does drain faster the higher you crank the volume, so if you plan to blast it for hours on end you'll likely want a USB-C battery with you. But more likely than not, it'll cover your entire event, no problem. I used it often while on a trip for a week - mostly at lower volumes - and never actually needed to charge it. It feels well built and substantial, despite being light enough to carry with you. Overall, really exceptional audio quality. You'll be amazed at the bass it pumps out - especially if you increase it via the EQ in the Bose app. Unfortunately, there is no AUX port, nor can you do audio via USB-C. Perhaps that can be enabled via a software update, but I wouldn't count on that, so you are limited to Bluetooth connectivity. There are certainly cheaper options out there for something like this, but you'll be hard pressed to find something with this level of audio quality and portability, so the price seems justified. If you primarily care about audio quality - and don't care about price or size or weight - the Max is the way to go. But if you want any real semblance of portability, you won't be disappointed by this. I don't have the Micro to compare against it, but this is only slightly more and seems like the right call.

Rated 5 out of 5 by from Great Speaker in a Small Package I've had this for about a month and am loving it! It is a fantastic size for carrying around with you, while feeling sturdy enough that I'm not worried about it getting destroyed on a hike or if stored in my truck with other gear. The sound is incredible for the price and size of the speaker. In comparison to the SoundLink Max, the bass at first felt a bit lacking. However, when compared to other speakers in the same class, it's top notch. I couldn't recommend this enough

Rated 5 out of 5 by from Little speaker with a bang. Small speaker with the perfect sound. It’s nice, light and portable. You can take it to a picnic or just play around to the house with it not be overly loud. The sound is really amazing. I look at it as a mini version of the max.

Rated 5 out of 5 by from Durable and User-Friendly The Bose SoundLink Flex, true to brand, has amazingly powerful sound for its small size and is packed with thoughtful features.  This model is built for adventuring, particularly with friends.  Don't let the size fool you; this is a party speaker.  It can even connect with other portable Bose speakers in cases where you want more coverage. The battery life is enough to keep your musical motivation going through a full day of travel.  I was not able to charge my phone from the Flex as with its larger cousin the SoundLink Max, so don't expect it to double as a power bank if that is a priority for you.  In terms of size, this is a Goldilocks speaker.  It won't fit in your pants pocket (though you can carry it in the kangaroo pocket of a hoodie), and I wouldn't take it on ultra lightweight backpacking trips where every ounce counts, but it's just the right size to hang off of a pack and take camping or boating.  It's also perfect for beach or pool parties where you want a solid sound system that can stand getting wet. As someone who does a lot of outdoor adventure travel, this is the long-wearing speaker I've always wanted.  While the price point makes it an investment that I would normally think twice about risking on rough trips, the Flex is durable enough to withstand rain or hard bumps, and the sound quality is worth the cost.  The built-in webbing loop makes it easy to hang from a hook or carabiner, and I feel confident hanging it from a backpack without having to fret about it bumping around.  The loop itself isn't replaceable but seems durable enough to last.  The silicon coating can pick up dust, but it's extremely easy to clean due to the water resistance; just give it a rinse.  It even floats so can survive an accidental plunge with no rescue diving required! There is almost no learning curve but plenty of options for customization through the app.  It's extremely easy to connect to devices or other speakers via Bluetooth, adjust the EQ, and set a shortcut.  There aren't many buttons to learn, but you can make it yours within about five minutes of opening the box.  I'm the kind of person who listens to music a lot, because it makes everything- even homework or housework- feel more epic.  The Flex works for that just as well as for true, outdoor adventures.  So, if you want your next excursion with friends to have an epic soundtrack, this speaker is a solid choice!
