Customer Ratings & Reviews

The Soundlink flex is the latest entry from Bose into the excellent Soundlink line. This model is compact and relatively affordable. It features IPX67 dust and waterproofing, meaning it can handle sandy and dusty conditions found outside or a quick dip in a pool if it gets knocked into the water. Visually, the Bose has clean lines with a set of control buttons on the top, and a USB-C (YAY) charging port on the side. The control buttons control power, volume, Bluetooth, and a multi function button that can be used to invoke your device’s voice assistant, take calls, etc. A front and small rear grille dominate those surfaces. Outside of the grilles, the entire thing is wrapped in soft-touch silicone to help with bumps, and it features small raised feet for either sitting up on the long bottom edge or flat on a table. A nylon utility loop finishes out the outside of the speaker. Curiously, there is no cover for the charging port. If you are going to take this speaker to the beach or some other dirty environment I would suggest finding a USB-C dust plug to seal it up and keep sand and other grime out. All of this is great, but how does it sound? This speaker has a single active driver and a passive radiator, as well as some internal sound routing between the two. Overall, the sound is tuned to the typical Bose signature sound, and for its size, sounds very good. It’s clean and clear at low to moderate volume, although you can hear it start to strain when pushed at higher volumes. Physics does come into play with a smaller driver element at some point. Bass is surprisingly present, although not thump your chest level. It does manage to play a very wide range of tones from the single driver, which is impressive. Compared to the Revolve+, it isn’t quite as clean or powerful, but for the size and portability, it’s quite good. This speaker also features a positional sensor so it can tell if it is upright or laying flat, and it changes the sound profile slightly to optimize for those orientations. Set in the middle of a table flat, it creates a good all around sound, and upright can fill a room or be heard clearly outside. One really cool thing is linking multiple Soundlink speakers together in “party mode”. This allows even my older first generation Revolve+ speakers to link to this new model, and create a mesh of sound around an outdoor patio. You can also set them up in left/right mode with multiple speakers for stereo sound. I used the party mode for a couple of hours between a Revolve+ and the Flex, and only had an occasional sound drop as people were walking between the speakers. Very nice feature and good to see Bose continuing to support various generations of Soundlink speakers. Overall, the Flex is a nice addition to the Bose Soundlink lineup. It’s well priced, and will create a great sound that will have your friends wondering how such a small speaker can create as full of a sound as it does, especially the tonal bass response. The addition of USB-C and the utility loop are nice touches, along with dust and waterproofing in a compact size, this speaker is built to go along on your next adventure.

Another excellent product from BOSE. Sounds like no other Bluetooth speaker. Reach, first quality sound across the space. "EXCELLENT"

Gifted this to a great friend and he truly enjoys using this speaker!

Its worth it truly this is a quality product and the sound is impressive and I don't think anyone buying it will be disappointed at all

Sound quality is good except for the battery which doesn’t last long.

This is a nice little speaker. I gave it 4 stars because I wish there was a little more bass!

This thing really works well i'm happy to have it!

I bought this because I thought it would outshine my older Sony speaker. I was wrong. It will serve its purpose. But now I know.

It’s decent… lacks in the mid range… got it on sale.

Good sound short battery life if the battery was better Id buy 2

Good portable Bose speaker. It he sound is ok. They could of do better.

I have used a few noise canceling ear pieces. These are the best I have ever had. Quality is fantastic. Battery life is great.

Good bass response. For the size it is impressive.

Got this to replace my old Soundlink 2 that finally quit working after about a decade of daily use. The sound is really amazing.

The speaker is great. I would give 5 stars if the app had an EQ built in.

the volume for phone calls is very low. need to control volume like the music

Not as loud as I thought it was going to be but it has good bass.

Nice speaker, battery life at full volume is kind of low

Really, really enjoy listening to my music coming from a light weight "boom box". Happy I made the purchase. Bose did not disappoint.

This speaker has great sound quality and clarity. Not disappointed at all will be buying more for party mode. Cant wait
