    OK so I have been using this product now for approximately 24 hours and I must say that I am highly impressed with the quality of the sound as well as how easy it was to use. I will be providing a this review so that you can make your own decision prior to purchase.So immediately from the start I did notice that the speakers were very heavy indicating high quality product and high quality magnates were used in this speaker. So the speaker itself weighs approximately 2 pounds and seems to be very durable .I did charge the speaker for approximately 2 1/2 hours until it reached full. You can tell the percentage level by pressing the power button onceI then downloaded the bose connect app and installed it as normal. I did notice it came up with two blue tooth connections one I believe is for the app and one is if you don't use the app and just decide to hook it directly to bluetooith. Once the app was paired I was able to play music through it. While the plain non equalized sound is good I feel it could be better. Which is why I used the equalizer built into my phone to adjust the sound. The Bass in this small speaker is a much better and much more defined than most bluetooith speakers currently on the market. I have had the privilege of using professional grade speakers as well as lower grade speakers and I will tell you that that this does measure up to professional grade sound. Keep in mind, the sound quality is only going to be as good as the music you put through the speaker. I had put high definition audio through this speaker and it was crystal clear. At lower volumes and high volumes. There was almost no distortion detectable however I did notice some at a very high volume when the brunt of the speaker was covered. Please note do not cover the brunt of the speaker as this is I believe classified as an open air speaker which is what defines its bass. So let's get on to the specifics now. The battery, it's not bad I had this playing at about 60% volume for approximately 7 1/2 hours straight and for the remainder half hour it was on the maximum volume and when I finally shut it off it still had 30% power remaining. That being said, I believe this should easily get between 10 and 12 HRS to a full charge. It does take approximately 4 hours to charge it from almost nothing . But if you have a three amp charger like I have it does appear to go a little quicker.One thing to keep in mind and it is recommended that you use the charging cord that comes with the unit is that if you use an extended cord it will take longer to charge. This is why bose recommends using their charge cord. I will say that im highly satisfied with this purchase. And feel very comfortable giving this a five star rating despite the 4 hour charge time. The speaker measures approximately 3 1/2 inch by 8 inches with a 1½ inch fabric a loop the depth of this speaker measures at about 2 inches. One thing that I should know right now is that this does not come with a Caribeaner clip. I will recommend that if you like the option of using the clip then you should definitely get a clip with a flat base so that it will fit correctly.So to sum up this review this is a no brainer and bose has continued to make their presence known for quality over quantity. Even in the harsh economic environment of the United States this $139 speaker packs a punch of easily a 200 dollar speaker.If you are looking for a great sounding long lasting bluetooith speaker look no further because this is it.As with all of my reviews I do recommend that you follow them because I will be updating them periodically sell as to keep you properly informed.
    I use this speaker for sound via Bluetooth on my Chromebox. It doubles as my portable speaker when I go for a hike or two the beach, connected to my phone.Overall, it works very well and sounds great. Connection to the Chromebox can be a little fickle to establish sometimes, but is reliable once it's connected and sounds great. I think this is a perfect use for a speaker like this.If you're looking for a small speaker to use modestly in public to watch YouTube videos, for example, this is probably not the one you want. It has some fullness/bass to the sound and lacks a native EQ control, so it doesn't do quiet/discreet very well. It's also kinda chunky to carry around, but totally fine to toss into a backpack.It may not be the right choice as a shower speaker either if you live in an apartment. It can withstand the water/steam/humidity, but it gets boomy in the bathroom real fast. At low volumes, it's fine though.Battery life on it seems outstanding at lower volumes. I don't have any specific figures, but it gets pretty loud and I don't need to turn it up high at all.The little fabric loop on it works well and feels sturdy. It hangs with a carabiner just fine. It also stands up on it's long bottom side well, i.e. you don't need to prop it up on anything.Lastly, the silicone exterior with metal grille feels sufficiently rugged for indoor and outdoor use and toting in a bag. I don't see a need for it to be in a case, personally.Very pleased with this speaker and I would recommend it.
    The very first thing I noticed was the weight of this thing. It had some heft to it - and that is a good thing. It did indeed turn right on, and I did use the Android app to connect, so connection was easy peasy. I haven't had to use the app again since that initial pairing. I liked the overall look and feel of the speaker, though I am not much into aesthetics. It is certainly not unattractive. On to the sound review...I'm a fairly old guy so I have a strong bias toward Bose, meaning I've long respected the sound Bose gets from otherwise unconventional sizes and shapes. Haha. So I spent time moving the speaker around to various spots, in various rooms, in various spaces and such. Lord you can really tell the difference from place to place! That is textbook Bose. Find the sweet spot location - find the sound you want. So I was pleased to find this was the case here. Speaker placement can have a huge impact on the sound!Sometimes the speaker can sound thin, sometimes heavy. It all depends upon where it's placed. Some people might find this disconcerting. Trust me, that is the nature of sound. What I found was that outdoors this speaker sounds thin, losing much of the lows. Placed in a more constrained spot and the bass can overwhelm. All this is merely information - NOT A COMPLAINT! What I am saying is, that even for the low price, this a dynamic speaker. You gonna have fun playing with placement and location.Okay the bad. Not very loud. And it does not sound good at max volume. Gets messy, tinny, meh. Oh well, it's not a huge speaker, and it is at the bottom range of price for Bose. Maybe I should be thankful Bose is offering cheaper options. It's loud enough I suppose. But overall the middle sound range lacks clarity - at any volume. The highs are a bit tinny - at any volume. This is not an audiophile's dream, it will not replace your high def sound system. It is indeed a portable speaker. (I make a general comment below about the general state of modern streaming, wireless, etc., that coincides with this.)As for functionality, it's pretty bare bones on the actual device. I found the pressing of the "buttons" to be a bit stiff, but I can handle it. Obviously the majority of control is going to come from the broadcasting device. The volume of the speaker matches the volume of your phone (etc.) meaning it's using your personal device for volume control - not its own separate volume control. Obviously there are volume controls on the speaker though. This speaker is merely an extension of your personal device. It offers ZERO control or tweaking options outside of that. The app doesn't either.Bottom line. Provided this speaker continues to function, I am pleased. I’m sure it’s possible to find a better sounding speaker, even for the price, but I got tired of looking lol. I will try to update this review once I've had a chance to test the battery life, charge times, etc. I think the app has a battery meter? Hard to tell. These days you get next to no info on the devices you purchase. If it is a battery meter, then it appears to drain fairly quickly. But again - who knows. Virtual meters like that can't always be trusted.--------------------------------COMMENT ABOUT THE STATE OF TODAY'S MODERN LISTENING EXPERIENCEI made comments about this speaker's sound, but it's really hard to blame Bose. Sound quality is dependant upon many factors. Blu Tooth. My phone. Spotify lol. Buffering, bandwidth, compression. Sometimes the tunes on Spotify (etal) can be very poorly delivered. Whether it's the compression and quality of the source, or the speed of transport, I often get mixed results when streaming. No way has modern streaming come close to matching analog source, analog delivery. It is what it is. It's convenient, and that is the sacrifice. I accept it, begrudgingly at times, but I accept it. In some situations my 20 year old dual PC speakers, playing FLAC files, can sound better than this Bose streaming Spotify. They can certainly proved a much clearer sound, especially in the middle. Sound is, after all, an analog wave that vibrates your own inner drums. But I do have hope that future advances will improve the whole streaming mess. And it is a mess bwahaha!
