Customer Ratings & Reviews

This Bose SoundLink Flex portable speaker works great. Very easy to set up, and has great sound.

Christmas gift for my wife. She loves it! Lots of low end. I love it, too!

This is the best Bose I ever have and sound amazing

Purchased this speaker, open box and I could not be happier! Easy to use and great quality.

From the moment I powered on the Bose SoundLink Flex II, I was immediately impressed with its sleek design and build quality. This compact, portable speaker doesn’t just look good; it feels sturdy and I see no issues using it at home or on the go. The audio quality is good. For a speaker of its size, it delivers a surprising sound experience. The bass is deep and punchy without being overwhelming, and the mids and highs come through with clarity. I tested it with various genres, from classical to hip-hop, and it handled everything with ease. This speaker is especially good when you crank up the volume. The PositionIQ technology optimizes the audio base on what position it is in. It’s lightweight and compact enough to fit into a backpack or tote, or hang off either via the built in strap. The stated battery life is 12 hours, and I actually exceeded that during my initial "let's see how long this lasts" period and the speaker recharges quickly. The speaker has an IP67 rating, meaning it’s dustproof and can withstand being submerged in water. It also floats, but it's not designed to be used in the water but can withstand a drop in a pool or rains storem. The Bluetooth connectivity is straightforward and reliable. Pairing it with my devices was a breeze, and I appreciated the strong, stable connection that didn’t drop even when I moved around the room. It also supports voice assistants, which adds a layer of convenience for hands-free control and has various setting available in the Bose app including custom sound setting. The Bose SoundLink Flex II is a top-tier portable speaker, that also has the ability to utilize a "party mode" where it will share a connection with other Bose speakers. Whether you are an audiophile or someone who wants a reliable speaker for outdoor adventures, this little powerhouse won’t disappoint.

Pretty nice. Good sound, wish there was better bass. And battery life. But for the money good buy.

Yes, this speaker does music great. It gets loud, the eq makes it extremely customizable, its super rugged and durable AND waterproof, and its got really good battery life. Having put this speaker through everything, I can confidently say that its #1 best use is for podcasts. If youre someone who likes to set this speaker down and listen to podcasts, stand up comedy, or just youtube videos, this is absolutely a 100/10 speaker. The mids and voices are extremely loud and clear. Especially when you use the bose app to turn the bass down slightly. Its amazing to fill your space with vocals even at its tiny size. Yes its amazing for music but I believe anything with an emphasis on human speech is just perfect for the bose soundlink flex.

The Bose SoundLink Flex (2nd Gen) Portable Bluetooth (5.3) Speaker packs so much quality sound into a small package - I would say it is incredible, but it is BOSE after all. Since the day I got this, I have been absolutely loving it! The speaker is charged via a USB-C cord, which is included, but I have those all over - for my phone, etc. so I simply plugged it into one to charge while I downloaded the Bose app. The Bose app has a handy little equalizer you can set, but really other than that I don't see where I will have much use for it. The speaker came almost fully charged, so it didn't take much time to be ready to go. Intuitively, I pressed the bluetooth logo on the speaker and searched for the speaker name on my phone's bluetooth list. It connected immediately and, though Bluetooth speakers generally have approximately 30' connection range, I was able to walk all over my house carrying the speaker and even outside into the yard without any connection issues at all. How is the sound? MAGNIFICENT! Connecting to Spotify or my phone's playlist, I get that amazing Bose bass that fills my soul with incredible sound that I can feel. The treble is awesome as well, and can standout more for you if you do an adjustment in the equalizer. I prefer a little more bass over treble with less mids. The sound is clear and amazing at any level and this thing can blast the sound! If you're having a party, this is all you will need for your playlist. With its shortcut button capability, you can pair it with another SoundLink speaker for even bigger sound. You can even use that button to create a shortcut - I chose to use it for Spotify and when I press that shortcut button, the speaker connects to the Spotify app on my phone. Bose claims a 12 hour battery life, which is long enough for a day in my life, though they do state that at maximum volume the battery will last approximately 3 hours. The Bose SoundLink Flex (2nd gen) is light to carry at just 1.66 pounds and has a nice feel with it's soft-touch, silicone-wrapped finish and it is dust proof and waterproof (rated IP67). This is truly portable because Bose built it to withstand, as they say: "drops, crushing, shocks, and rust", and it has a small hoop to hook it onto your gear. As I was writing this review, my phone rang and I was able to answer it via this speaker! There is a built in microphone so the caller was able to hear me, but said I was fading in and out, though I was sitting in one spot. I was able to hear them clearly. The other problem was that I didn't know how to hang up via the speaker - I had to have them hang up (of course I could have used my phone). This Bose SoundLink Flex (2nd Gen) Portable Bluetooth Speaker puts out absolutely incredible sound in a small speaker (H 2.06 inches, W 8.661 inches, D 3.78 inches). This is quality that I appreciate and that I know will last for a good long time. It is everything I want in a portable speaker and I would HIGHLY recommend it to anyone in the market for an excellent quality small Bluetooth speaker.

I absolutely love this speaker. It's really amaxing

Bought several as presents and was so good bought one for self

I’ve been using the Bose Soundlink Flex II for a little while now, and honestly, it’s quickly become my go-to portable speaker. Right out of the box, the setup was super easy – it connected to my iPhone in seconds, and I was ready to play my music. For such a small speaker, the sound is amazing! It’s got this rich, deep bass that you wouldn’t expect from something so compact. Whether I’m listening to music or catching up on podcasts, everything sounds crisp and clear. Plus, if you really want to step it up, the Bose app lets you link two of these speakers together for an even bigger sound. Perfect for a small gathering or an outdoor hangout at the park. Speaking of outdoors, this thing is built with that in mind. It’s both water- and dust-proof, so I don’t have to worry about it getting wet by the pool or dusty when I take it camping. It’s tough and portable, but still stylish enough to leave out in the living room. All in all, the Bose Soundlink Flex II is a quality speaker with serious punch for its size. If you’re looking for a portable speaker that delivers big on sound and durability, this one’s a winner.

Specs This is a very durable and portable speaker made by Bose, who really know their audio items. The size is right around 2” x 8” x 3.5”, yet it still produces the best sound across the board of any speaker I own. There are several different modes it can go into, including party and stereo modes, where you can connect two of them at once for a better surround sound by achieving both left and right channels. The battery life is quite long at 12 hours and charges easily with a USB-C cord. Bose also has an app that can be downloaded to control the speaker and tweak the sound. Pros Talk about durability! I don’t worry about it too much packed up with my gear because it’s water- and dust-resistant. The small size keeps it portable in most situations and wireless Bluetooth connectivity makes it easy to control. The app has very user-friendly controls but it’s not necessary to use the speaker. Cons 12 hour battery life is decent, but it takes up to four hours to charge it completely. For someone who usually forgets to plug in their electronics to begin with, this can be a problem. Although it’s durable, I’d also like a carrying case to prevent unnecessary scratches and whatnot from potentially rough traveling conditions. Conclusion You can’t beat this sound for this price through Bose; this is an affordable option for those who are sick of the tinny sound portable speakers usually carry. You’ll get clear and powerful sound through any genre of music!

The Bose Sound Flex 2nd Gen is hands down one of the best speakers I’ve ever owned. The sound is rich, clear, and surprisingly powerful for its size. Bass hits deep without distortion, vocals are crisp, and Bluetooth connection is seamless. Battery life lasts all day, and the build feels premium yet portable. Perfect for home, travel, or outdoor use—an easy five stars!

It is honestly astonishing how big the sound is coming out of this compact gem. I don't know what engineering voodoo Bose is using, but their speakers blow everyone else away in terms of audio balance. There's bass, but it's never overpowering. There's treble and it's never tinny. If I want to hear a song played well, this is how I play it. The fact that it's so small and lightweight (and water resistant!) means I can pick it up and go anywhere in the house, or throw it in a suitcase. And for the price, you can't go wrong.

The Soundlink Flex II is another quality product in Bose’s lineup. It’s built well with a silicone cover that’s durable, but also soft to the touch and easy to clean. Buttons are well protected and provide nice, tactile feedback with every input. Battery life is good and it charges quickly via USB C. Bose provided a USB C to USB C cable in the box, but no charging brick. Sound quality is good, but generally even across all genres. Seems to be best at ensuring clear vocals. The Bose app does give you some customizability by allowing you to play with EQ settings. The app also allows you to quickly change device connections, customize the speaker’s shortcut button, and access software updates. Since getting my speaker, I’ve taken it out on the boat and been using it while working on my project car. This single speaker got plenty loud while we were boating. It survived multiple hours in direct sunlight, being tossed around while under way, and being thrown in and out of the water. A full day of use went through about 40% battery at fluctuating volumes. I’m contemplating purchasing a second one and making mounts for them to rest in. We’ll see. The other day I had my speaker with me while I was repainting body panels on my car. Paint and dust makes its way onto just about everything while doing this. I was extremely impressed by how easy it was to clean this speaker off. One disinfecting wipe did it and it looks good as new. All in all, I am very happy with the Bose Soundlink Flex II. I feel like it’s a good value for a name brand, durable, and portable speaker. As long as it’s the right size for your needs, I’d absolutely recommend it.

I’ve been really impressed with the Bose SoundLink Flex (2nd Gen). The sound quality is rich, clear, and surprisingly powerful for its size. The bass feels balanced without overpowering the mids and highs. The build quality is excellent, and the waterproof/dustproof design makes it easy to use anywhere without worry. Bluetooth connection is quick and stable, and the battery life easily lasts through the day. Overall, it’s a great portable speaker and I’m very happy with this purchase.

It’s a Bose, so as you might expect it sounds great at low, mid, and full volume. It’s waterproof, sand / dust proof, and shock proof which I love in a portable speaker. It feels solid and well built. It has a built-in strap that seems durable and lets you clip it to backpack, etc. (clip not included.) The Bose app is simple to use. It also gives you EQ options with some preset options (Bass Boost, Bass Reducer, Treble Boost, Treble Reducer) and you can manually set Bass, Mid, and Treble up/down 10 each. Personally I think it sounds best at Bass +8 and Mid +2 settings for a deeper sound. I put it through the paces on every musical genre and most sound great (rock, rap, dance, folk, country, classical, etc.). Bass heavy music I’d love a tad more bass, but that’s difficult to achieve in such a small package. It sounds good whether laying down, upright, or hanging from its strap. Buttons are easy to use and intuitive including a configurable shortcut button (Link mode/party mode for combining with another Bose SoundLink Flex, Access with Voice Assistant, and Spotify) It has multi point connection to connect with 2 different BT source devices. Battery life is rated at a solid 12 hours, but likely depends on the volume you’re jamming out at. Charging is thankfully USB-C. It weighs about 1.5 pounds so it’s light, but not a featherweight. Overall a solid, rugged, great sounding portable speaker.

The speaker is compact enough to hold in your hand, tuck into your pack, or attach to the outside with its sturdy utility loop. The Flex 2 boasts a 12-hour battery life and an IP67 waterproof rating. With advanced Bluetooth 5.3, it ensures a robust, uninterrupted connection to your device from up to 30 feet away. Multi-point connections allow the speaker to be paired with several devices simultaneously, facilitating easy sharing of DJ responsibilities with friends. A notable addition is the Shortcut button, which provides quick access to various functions, including instant pairing with another speaker. Whether standing upright, laid back, or hung upside down, the SoundLink Flex consistently delivers optimal sound. Bose's PositionIQ technology detects the speaker’s position and adjusts its output for the best performance. Bose speakers are known for their agreeable sound, and the latest SoundLink Flex is no different. It offers clear sound with surprisingly good bass for its size, and the volume can reach impressive levels. Vocals come through clearly, and overall, the audio quality surpasses expectations for a speaker of this size. The accompanying app has been updated recently, allowing EQ adjustments through the Bose app. It also facilitates "SimpleSync" pairing with another compatible Bluetooth speaker. In Stereo Mode, one speaker serves as the right channel and the other as the left, while Party Mode synchronizes two speakers to play the same audio. The Bose SoundLink Flex (2nd Gen) Portable Bluetooth Speaker delivers exceptional sound in a compact form, embodying the quality I value and expect to last. It meets all my criteria for a portable speaker, and I would highly recommend it to anyone seeking a top-quality small Bluetooth speaker.

This is a great product. Clean sound. It can be heard even in very large places. I had to bring it to work on a day that electricity went down. I have used as a substitute to professional sound equipment. And no one saw any difference. I generally use it for home.. it is great for low gentle loung music or loud as a disco club. The quality of sound doesn’t change. It reproduces sound as in a professional entertainment, I didn’t need to recharge the battery since Christmas yet. Also, my house got flooded and one of the two speakers I bought went under water. I saved them both after that and when I tried to turn it on again, it seems to work! Unbelievable! Really good!

This Bose portable speaker is one of the best portable speaker I ever had . It’s so easy to use, just connect to your Bluetooth device and listen to your favorite music on the go while caring this compact speaker every where you go I even clip it to my backpack. The crystal sound and deep bass of this speaker is amazing just like I was expecting from a Bose product. The battery life last me all day while I care it to the beach without the need of charging it until I’ve got home. This Bose speaker is also dust, waterproof and one cool thing about this speaker, it also floats if you ever drop it in the water, you can also connect another Bose sound link flex speaker with the press of the shortcut on the device to make a stereo sound effect. The speaker can be lay flat, stand up or just hang it anywhere and with the Bose app you can adjust the sound the best way you like for an amazing sound. On the top of the speaker you get the power button, Bluetooth connection button, shortcut to connect more speakers, the play/ pause button and the up- down volume, it also have a built in mic that let you take calls. Using the Bose app helps you monitor the battery life, adjust EQ sounds, adjust volume or change shortcuts to the speaker.
