Ratings and Reviews

Rated 5 out of 5 by from Light but Powerful This portable speaker is a great all around! It’s small and lightweight, making it easy to take anywhere without compromising sound. I love that it's waterproof, so I can enjoy my favorite podcasts or music in the shower without worry. The battery life is impressive, I've had it for a couple weeks and haven't had to charge it since the initial charge. It's also rugged enough for outdoor adventures so I feel confident that I can take it anywhere without worrying about damaging it.

Rated 5 out of 5 by from Party Mode Activated! Named this speaker "Tiny Giant" because as small/portable it is, you'll still be able to bring the tunes wherever life takes you. Recently, brought the speaker with me on a trip. Fit nicely in my backpack with minimal weight added, not enough to feel I'm lugging around a heavy device. To me being able to listen to music as I get ready for the day or wind down is crucial, so big, big plus that this is a tiny but mighty lil speaker. I expect nothing less than a crisp yet smooth sound and this speaker delivers. When I'm at home that's when the real party begins, with the use of party mode between the SoundLink Flex and my Bose SoundLink Max. While doing chores and in/out of multiple spaces, situating one speaker in the kitchen and one in the living is quite the experience. It's feels luxurious even to be able to go about and not miss any music or my favorite podcasts. Impressed that there isn't a delay between the speakers too. Can't rave about this system enough and the speakers themselves.

Rated 5 out of 5 by from Maximum portability and sound I love love love this speaker. Bose makes great quality products so I wasn't surprised by this speakers' range. I travel a lot for work and was always missing a portable speaker. Not only can you fit it in your luggage but it can also fit in your purse/backpack. The sound is incredibly for a small speaker and it is 100% user friendly. So easy to connect and control. I only wish it came with a traveling case so it won't get scratched or damage in transit.

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.
