Great value very good. Sound for what this is
Color: Black
This is exactly what I needed. The sound is very good for what this is and it gets extremely loud without distortion. I use this to listen to my audiobooks on my phone, but the speakers on my phone are just not loud enough for me to hear when there’s any background noise. This speaker has solved my problem and it lasts all day on a single charge. I am extremely happy with its performance. The only reason I gave four stars and not five is because although I had my phone right next to it it took five tries to finally get it to pair with my brand new iPhone and it should have paired on the very first try. I almost started to think it wasn’t going to, but now that it has, I have not had any interruption I will see what happens after I turn it off and then back on if it will automatically connect, but I think it will be fine. You know what I think I’m gonna give it five stars anyway. Definitely recommend this if you don’t need a whole bunch of Bass but just clear music or speech this would work very well for you. It is a good value easy to use small enough to take anywhere. I don’t know what the battery life is, but I will basically be keeping it plugged in anyway, so that’s not an issue. ... show more

Back about 2005-2010 when mini Bluetooth speakers used to be the new toy everyone wanted (and you paid the price to be an early adopter) I was really into the fad and couldn’t stop looking for the perfect one. As a result I ended up with more of them than most dealers, speakers of every possible shape and gimmick. Some of them were knock your socks off impressive, including some so small I could stuff them in my carry on when I traveled so I could have music in my hotel rooms. These days there are a handful left from the major brands. One of them I was curious about was this series from Cambridge SoundWorks, a company I’ve known and respected since I worked directly with their founder Henry Kloss back in the late 80’s and early 90’s. Unlike the early days of Bluetooth mini speakers this little speaker was only nineteen bucks, probably the lowest I’ve ever paid for any speaker. I had mixed expectations. But I chose it both for its size and its shape, I was looking for a small personal speaker to put on the base of my desktop monitor to be able to listen to content at low volume without using my high-end Boston Acoustics system. The small size is truly impressive as is the surprisingly nice look and feel of the speaker. It is heavier than similar no name speakers and you almost have to wonder how they can sell it for such a low price. It comes with a micro USB charging cable and also a mini audio cable. The power switch is easily reached near the top of the back of the speaker where the audio input and charging port are also located behind a rubber flap. The rest of the controls are on the right side of the wedge. The speaker will pair easily with newer Bluetooth devices but it seems it is not 100% compatible with all of the many standards. For example it would not pair with my desktop computer without downloading an updated Bluetooth driver. The most important thing you probably want to know is how does it sound. I’m sorry to say that with almost 20,000 review written already, many of them high energy endorsements, I’m not as impressed. I have definitely heard better from similar sized, and even smaller, speakers. It’s not bad, but it’s not knock your socks off impressive. And it’s definitely not a speaker that you would choose if there were more than one or two listeners or for use outdoors. There are a couple of things to be aware of that I liked – one is that if you use the audio cable the speaker won’t shut off automatically after a few minutes like many other brands do, but it will shut off after 15 minutes of non-playing when used in the Bluetooth mode. Interestingly, if you pair it with an Echo device the power stays on all the time in battery mode so you would probably want to keep it plugged in to a power source if that’s your plan. I also like that you only hear the pairing sound once the first time unlike many other brands that make a loud sound whenever they are powered on or when pairing is successful. For me that is a deal breaker. ... show more

Great for the price

Bought mine 2 years ago. I have beat this poor speaker up. I use outside while working and take it on bike rides. Still works & sounds good. Shocking for how small it is. The charge hole is the one thing that seems loose.

this thing actually bumps
Color: Black
Review Image by Carl Freiermuth
this thing actually sounds really good.. it has two drivers, one for the left and one for the right.. they are about 40 mm each.. the grill is not removable, The speaker grill has such tiny holes that if you get it dirty, you can use some Scotch tape to remove what is stuck in it, most likely.. I listened to the entire album of licensed to Ill right after taking it out of the box and charging it a little, you can use it while it is still charging. now it may not thump like a pair of 12-in kicker solo baric subs hooked up to a 1200 watt digital monoblock amp.. lol but for a small speaker setup, this is definitely the best that I have heard at this size and price point. I'm really glad I picked these up. I'm the type of person that actually notices how the speakers in smartphones have been getting worse and worse... so I run an equalizer most of the time.. every pair of earbuds I have tried require an equalizer to reduce the sub bass and the extreme treble to make them sound halfway normal.. this little triangle box is so good, instead of reducing the sub bass and boosting some higher bass to get a little bit of kick.. this thing actually can reproduce Bass.. I mean not only was I able to leave the bass straight, but I actually boosted all the bass below 250 HZ and I only reduced the very high trebles because of my preference.. with most speaker setups if you want to hear the bass more, you would need to have the bass reflex side facing you, but this little system actually pushes more bass from the front of the drivers than it does from the passive bass reflex set up.. it seems the electronics are all at the end with the buttons.. which makes sense.. it has one large passive bass reflex side that gets driven by both of the drivers, so there probably isn't a divider between the two drivers at all, but I must say, the clarity is extremely good, even at full volume.. and the volume buttons on this control its own attenuator.. meaning that it does not change the volume setting of your device or smartphone.. so you can set the phone at what volume you want with the phone and then with the speaker box, you can also lower the volume on it.. I was playing it with both the phone and volume at full tilt.. but most of the time I would have it it with the volume turned down one press of the button from maximum on both the phone and on the speaker box. I'm actually calling it a speaker box because this thing is worthy. it's just over 5 inches long so it's big enough to really reproduce some bass.. surprisingly, and small enough to be very portable, plus the triangle shape should prove really nice for many applications.. I believe it has a decent sized battery.. I don't believe you can find something better for this price.. and the appearance? well the packaging it came in was way nicer than it needed.. and the appearance of the device, well this thing is very very nice, the end caps seem to be silicone which is awesome and it has very nicely designed foot pads to try to prevent it from moving around.. some reviews said that the base sounded better when the bass reflex side was facing downward but I heavily disagree.. I got the best bass from standing it on one end with the drivers actually facing me. I might actually buy a second one but this thing is nice enough that it doesn't really need it. maybe the sound would be even better with two of them paired together.. but I am very happy with it. I got a black one. I don't remember if it was available in different colors as I was shopping online quite a bit before deciding to try this one, I was assuming that I might return it if I wasn't happy with it but I'm definitely happy with it. it doesn't have the cool retro appearance that some speakers have, and I do love the retro appearance of smooth cones with concave caps that look like subwoofers with no grill in separate boxes.. but this thing sounds awesome and the shape is probably extremely convenient for me. it has some weight and the textures on it feel like top quality, and all of the print with words for information are on the side with the bass reflex which is just perfect.. I have not tried using it for a phone call yet but I see the singular pinhole where the microphone is at one of the corners.. it probably works just fine so long as you don't take a wad of refried beans and shove it into the hole lol.. very soon I will be playing some test tracks with crazy boosted sub bass. 😁😇 I wrote this review using the microphone on it, and I'm not even holding it up. so it does work, that's for sure. I believe the triangle shape, the decent amount of volume inside of the box and the angle of the passive bass reflex panel, combined with the fact that both drivers are acting on it, and that the large mass of the passive diaphragm, all contribute to its ability to reproduce... dare I say it.. sub bass. very cool. if I want to use it out and about, hopefully the battery can last, it's also cool that it has the 3.5 mm auxiliary input jack. I really like this pocket-sized system alot. ... show more

I've bought 3, and not because they broke. Love them!
Color: Black
I have now purchased 3 of these speakers over time for myself and as gifts, and each time I do, the packaging gets better, the speaker itself is better, charge ports actually updated to go with current USB-C standards. I love that you can link them together. I DO wish there was clip or attach point on there as I take them outdoors or in work areas constantly where I need space and wished I could clip it up out of way. I definitely put them through the wringer, but they're rugged and have withstood the test of time and elements over many years! I'm not afraid to take it with me when I'm on the water or in rainy conditions. The battery has withstood greatly as well; even the one I bought originally in like 2018 or something like that still holds a good battery life. Great speaker for the cost for sure. ... show more

Locked, Cocked and Ready to Rock...In smaller spaces
Color: Black
Like any product, this speaker has both good and less than good points. Having just received it, I am limited to immediate experience, although thus far more good than bad: Oontz Angle 3 Speaker (Geez, what a name!) appears well constructed, with good, solid feeling to it; although it isn't at all heavy. It doesn't have any apparition nor feeling of being loosely constructed, with good and tight fitting rubber seals and grommet for power/hard cable connection port. It was a bit difficult to get grommet open for charge the first time, but using some blunt tool removes it easy enough...Make sure you don't use anything like a sharp knife or like edged tool, because the rubber grommet could be accidentally cut easily enough when trying to lift it out initially. That's not a point for complaint, because speaker is supposed to be water proof enough to take in the shower, although user pamphlet expressively warns against full submersion. I as well like the fact the pamphlet is well written, easy to understand in explaining functions and set up, and I am thrilled by the fact it is completely in English; as opposed to multi language documents that are written in several languages at microdot font. It's definitely a high point for me to see the instructions are completely in English, but higher still, designed and engineered in America! It is manufactured in China however (What isn't these days?), and I would have preferred American manufacturing and paid more for it if it was. Bluetooth pairing with my iPhone 7 Plus was simple and easy, and activated the pairing mode was very easy, requiring only the user depress and hold the Bluetooth button, which is lit when in use, for a few seconds until it reacts by fast flash. After that, it's just a matter of selecting it in iPhone settings menu, and it will continue to "look" for the speaker after powering on and off, or turning it on for other sessions. Although it hasn't yet been a problem for me with Oontz speaker, it is sometimes important to reselect chosen device in iPhone if you want another device selection (such as Plantronics headset or other device); although that's iPhone's issue and not Oontz Angle 3 Speaker's. So how does it sound? (Thought you'd never ask!): It's a fairly good, responsive speaker with good resonating effects, deep base response, and good mid and high end response. Bear in mind this is a small, portable speaker running off an internal battery, so if you're wanting several hundred watts to rival Bose speakers, this ain't it! But it's no slouch of a portable speaker either, and it would be absolutely perfect for bedside, hotel, bathroom-shower morning music and like use. It would be perfect for kids' rooms, although no kid is truly happy unless he can annoy parents with high volume, preferably including the neighbors while at it, and this little speaker just isn't made for window-shattering output. It gets a little tricky if your playlists are "eclectic from hell" like mine are! Neal Young and Rolling Stones comes out great using iPhone's "Small Speakers" EQ setting, Temptations does better using "R&B" or "Pop," and I have yet to isolate best for Grateful Dead...But "Rock" comes near (but not quite there) the mark. Junior Walker imposes a problem I have yet to solve...And who can live without? All in, you'll likely find a good setting for one album or genre of music, but you would do well to expect to use more than one if you really like your music like I do. Still, that no buzz killer by me. I like it just as much! Again, if you want to share your music with residents two flights up or around the block, this won't be your answer, but I have a 700 watt Yamaha receiver to accomplish that need anyway. Oontz Angle 3 speaker comes partially charged enough to pair and try right out of the box, although I soon connected it to supplied cable and to a USB charger I already had. Instructions say it can take "5-6 hours to fully charge a low battery," but how "low" it is on delivery is anyone's guess. Good news is you can listen while charging it, and it's recommended to fully charge initially. I note user pamphlet states higher volume level will affect play time, but it says you'll get "up to 12 hours at 2/3 volume." Hands Free function for telephone user however, does present a weak point. Sound of incoming party is reasonably good and nothing to complain about, but the microphone on the Oontz Angle 3 does indeed leave much to be desired! I tried it in a reasonably quiet surrounding without background noise, a little less than two feet away in normal voice that I would use with other hands free telephone devices, using my own voicemail message to gauge sound quality. The result was very tinny, with a very distant reception that gives perception of being very far from the microphone when you're not. Since I don't expect to ever much rely on that function anyway, at most to grab a very important call while in the shower or like setting, that's no deal breaker to me. If you expect to make a lot of hands free telephone use however, you should be aware of that and immediately test it to see if it's something you can rely on. The upside is it automatically went into telephone mode and enabled the microphone without having to switch, and it immediately returned to playing music once call was terminated. Since cell phone issues can be sourced to any number of reasons (connection, device location, etc,), it isn't always evident for where the problem cause is...So test that soon, once you get it! All in, end of the day, and bottom line: This is a great deal! I believe I am getting more than what I would expect for $25 Bluetooth-connected, small portable speaker, and it sounds really good in the entire room, and isn't limited to being sweet-spot in front of it. The base comes most from the bottom of speaker and has easily discernible mid and high range outputs, which is hard to find on small speakers at all, let alone portable AND Bluetooth. It will easily be benefited in smaller space with tiled walls like most bathrooms tend to be, and neither it nor the manufacturers fear a hot shower, provided you don't ask it to scrub your back. It would work very well in a kitchen, bedside or hotel room without causing the front desk to ask you for an much earlier check out...Like now or sooner. It has it's limitations like anything else, but for reasonable volumes and user expectations, it's still a score! There's only one thing I would want that wasn't part of the buying experience: Free shipping from Amazon (Hint, hint!!). I would buy another and I do recommend it! Thumbs up, stars, and a few backflips...And nobody is giving me anything for this review. ... show more

This is probably a decent speaker for the price. But I have an older version (10 yrs plus) and it's still going strong and has a much better sound. Clear and more bass. New model is tinny, some distortion (even with my phone right next to it) and bass is almost non-existent. It charged up and paired just fine and is nice looking.
