    • Excellent Product
Color: Black
What can I say.... it's a BOSE. I got this because I loved the Micro Soundlink, which is also waterproof. Or I guess water resistant, however the soundlink was dropped in a pool, while we were having a fiesta and I swam down, picked it up and it was STILL playing. I haven't had any issues with this, the sound is clear and fulll, it's an excellent price, the size is perfect and you can attach a carabiner to the loop and hang in on a backpack or a bike! 5 solid stars!! ... show more

I bought this speaker because I wanted a way to listen to music while grilling in my backyard. I had no expectations of it being a “party” speaker or anything of the like. But my goodness. This speaker punched above the weight I expected and what reviewers claim. They say it’s good for less than 10 people. Probably true if in an enclosed space. Outside, standing in the corner of my backyard about 40+ feet away, the speaker volume is at about 60-70% and with the air conditioner droning on I can still hear this speaker, and the vocals are clear, the instruments are clear, and there’s even some punch of the bass. It’s so much more potent than I expected. I actually bought a second one (the one pictured) so I could utilize Party Mode and Stereo Mode, and then these are far better than they have any right to be. The bass shook through the house at about 40% volume, to the extent that my wife actually asked me to return one and get some noise cancelling headphones if I wanted to be blaring music all day. 😂 So (for now), I’m obliging and returning one, but honestly, I don’t want to. One of these speakers are great. Two make a great portable stereo system. Now for the feature set. Key selling points for me were: 1. Durability. It’s made of steel and silicone, is rated to withstand a dunk in water and dust. You can enjoy this in the yard, on your workbench, swimming, shower, etc. I live in high desert, and the wind blew over these speakers from a table to the ground and they didn’t have a single dent or scratch. Which leads me to… 2. The device has sensors built in that detect its positioning, so the sound quality was maintained even if it’s on its back, side, or face down. None of the other products that compete in this segment offer that function to my knowledge. 3. Unlike other products that I considered, this sounded good right out of the box. Anker (Soundcore) offers some great competition in this segment, but needs the EQ tweaked to shine. They’re not bad by any means, but I wanted things to just be simple. Power on and go without fuss. Bose delivered that. There are similar products for sure. Ultimate Ears will also let you pair two portables to create a stereo, but it lacked the intelligence that this speaker did. We already covered Soundcore. Tweak with the EQ, save some money, you’ll likely be happy. These speakers do often go on sale, and I purchased mine used (like new) and refurbished respectively. The “Used” unit was actually brand new from Amazon, broke the seals on the box and everything. Far as I could tell, the speaker just rolled around in someone’s trunk unopened before returning. The box had some cosmetic damage but no dents, broken seals, and all accessories were obviously also unopened. Refurbished unit came straight from Bose. Also came with all accessories and literature, just a box that was labeled “Refurbished”. Warranty on refurbished or new are 1 year regardless. I bring this up to encourage you to save some money, reduce some e-waste, and buy secondhand like I did. No judgments if you want to go new of course! But I got 2 speakers, one that was new in reality, essentially $100 off the set, and I didn’t miss out on anything in terms of product or warranty. $150 is pricey for a speaker, but $103 for a Bose speaker is not. Especially one that can literally go for a swim. Four criticisms I’d like y’all to know. First, compression above about 75% volume. Your bass will flatline above this point to maintain clarity of the track as a whole. In reality, that just means you go from a slightly warm tone to a very neutral tone of sound profile. No big deal unless you’re blasting EDM, Hip-Hop, the like. As I said, this little 20W speaker carries enough punch that 70% was more than enough to fill my backyard. Second criticism is no biggie for me, but worth bringing up for those shopping the competition. I didn’t want to fuss with an EQ, but competitors do have them to fine tune your sound. Consequentially, the app is basically useless beyond seeing your battery life and an option on how to do party mode (not required). Third criticism is truly a nitpick, but why do I have two apps for my Bose products? Why do I need one for headphones and one for speakers? Wish Bose would put all their portable speakers and headphones into one app. You could easily knock out criticisms 3-4 by just putting this speaker into the Bose Music app, like my QuietComfort Headphones, and this VERY speaker's big brother, the Soundlink Flex Max, is already there. Why the heck is the Soundlink Flex not in Bose Music, with a basic EQ like the others? Fourth, this uses outdated Bluetooth. No big deal. Pairs easily. But don’t expect to watch movies or game off of this. Latency is too high. Anyhow, enough of that. Go buy one. Or better yet, two. You won’t be disappointed. ... show more

    • Well Worth the Investment Due to Good Quality and Design
Color: Black
This speaker was the second replacement I purchased, and I am glad I did. In stark contrast to the first one I bought, this unit is solidly built and well constructed. It feels and looks very sturdy and doesn't give me the impression that it will be easily broken or damaged. The design is better than that of other speakers I've owned in the past. It has a good, broad surface area, so the sound isn't at all tinny, and due to its shape, it does not fall over, even if put onto a softer surface. Getting it paired to my device was fairly easy. I like the layout of the buttons. I really did not expect a speaker this size to sound great. I wasn't in the market for something that could dominate an outdoor party, so this would have been tolerable. However, I am very pleased with the sound quality. It's neither too tinny nor too heavy, and I find it works just as well for music as it does for other audio. Mainly, I use it in my room to read audio books, and it does a good job; I'm sure it would be quite a nice choice for those of you who actually are looking for something to use outdoors. To get that good sound from it, you don't have to blare the volume or turn it too far down, and the sound quality is superior to that of some larger speakers. There are a couple of other nice features I sincerely appreciate. First, I frankly find it obnoxious that when you turn on many speakers, or turn them back off again, for that matter, they play an annoying, little bit of music that is far too loud and impossible to disable. I'd rather have them simply beep, if that much, or do as this one does and give you the percent of battery power left. I like that this takes a USB-C cable--no more irritating, fragile micro USB for me. Its battery life is quite good, which helps me because I sometimes tend to forget to charge my things. Last but not least, this speaker is the only one I've had that beeps to acknowledge that it is charging when you plug it in. The sound is unobtrusive and quiet, which I prefer. Overall, you'll find this to be a very wise buy. You can get cheaper units, certainly, but spend a bit for this, and you won't regret it. ... show more
