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.

Let me preface this review by saying, I was provided a free sample for testing and review. I explained to the manufacturer that I would provide an honest review of this product. All experiences with this product and all opinions are solely my own.

I purchased the prior generation of this speaker, the OontZ Angle Plus, so I'll be able to compare them. The Plus has crystal clear sound and good bass. I really enjoyed the Plus, but where the Plus needed some improvement was with its volume and bass.

The new OontZ Angle3 significantly increases the volume and bass, but more importantly it retains and improves upon the crisp and crystal clear sound of its predecessor, plus it adds an ingenious bass design. More on that later.

What's included in the package:

1 - OontZ Angle3 Speaker
1 - Micro USB Cable
1 - 3.5mm Audio Cable
1 - Quick Start Guide

The OontZ Angle3 is a great sounding Bluetooth speaker, in a small compact package. It weighs in at about 9 ounces. It is 5 1/4 inches long and about 2 1/2 inches high. It will basically fit in the palm of your hand. Please refer to the pictures I posted. It also retains the angular design of its predecessor, but now has a silicone rubber type finish on both ends of the speaker. It's still void of any sharp edges. It's a great looking speaker, with a unique design. I like this Angle3 design better than the Plus.

It's significantly louder than the Plus and has nice bass, for a unit that's this small. If you enjoy music that has some bass, this unit should meet your needs and be truthful, the sound that comes out of this speaker is mind boggling to me and the size of this speaker belies that fact!

The passive radiator, which produces the bass in the Angle3 and most Bluetooth speakers, is located on the bottom of the unit. If you place it bottom down, the bass effect is more pronounced. If you want a little less bass, you'll stand it on end. When it's bottom down, the bass has a nice little thump. I believe this was done by design and it's an ingenious feature.

Be careful where you place the speaker bottom down, because it does want to move when playing music with bass. The speaker has pads on the bottom, but they work better on very smooth and glass surfaces.

You can hear that Cambridge Soundworks spent the majority of its time improving and refining the sound of the Angle3. That focus on improving acoustics shows up big time in this tiny, but crystal clear and loud speaker.

There's no distortion at max volume. The speaker has 10+ watts of peak power. It's now loud enough to fill up your backyard party with clear, great sounding music. My wife heard me playing music upstairs and she was in the garage. It's plenty loud!

All my music testing was done using Spotify. Speaker was set to full volume and iOS volume was set two clicks from max, for most of my testing. I also tested both settings set to max.

Bluetooth connectivity is super easy. It connects from one device to another effortlessly. I found you don't have to press a button on the speaker to pair it with a different device. I like intuitive functions and this one fits the bill. It also has a speakerphone function. You can play and pause your tracks from the device as well.

The OontZ Angle3 doesn't have all the options others have. You don't get NFC support, a micro SD card slot or the ability to skip tracks using the speaker controls. There are other Bluetooth speakers that have these options, but if you value how well your music sounds over a myriad of options, this beautiful sounding speaker is for you.

The Angle3 has an IPX5 certification, which makes it splash proof and dust proof. Great for the shower and other wet environments. Don't be afraid to shower with it or have it out in the rain. It can't be submerged in water with this IPX rating.

Battery life is about 7 hours, at 60% volume. It will be less at higher volumes. This is definitely less than the Plus unit, which does 12-15 hours of use. You have to take into account that the battery is driving much more sound and requires that extra battery power. I personally like the trade off and all that's required is to charge the unit a bit more frequently. A battery status symbol shows up in my iOS devices.

If you're like me and aren't interested in the all the above mentioned options, that you may never use and just want a beautiful sounding speaker that's main focus is perfecting and delivering crystal clear sound, than this speaker is an excellent option to consider.

To me, the OontZ Angle3 has no real negatives to mention. You could quibble about having more features, but I really don't consider that a negative. I'd rather have a great sounding speaker, over more features. In my opinion, this is a great Bluetooth speaker for the price.

The OontZ Angle3 is a very solid speaker, that now has outstanding volume and good bass. It retains and actually improves upon the crisp highs and strong mids of its predecessor. I like that Cambridge Soundworks is actually focusing on sound quality and not loading up on tons of features.

I can highly recommend the OontZ Angle3.

Thank you for reading my review.

From the moment I unboxed the OontZ Angle 3 Bluetooth Speaker, it was an unspoken understanding that my auditory experience would never be the same. A journey that began with a sprinkle of skepticism has metamorphosed into an unrivaled relationship between man and machine. This isn't just a Bluetooth speaker; it's a harmonious blend of top-notch sound engineering, aesthetic beauty, and unparalleled functionality, ensuring every listening moment is a treat for the senses.

While it's a temptation to be swayed by the plethora of high points, the aim of this review is to offer a balanced perspective. I will delve deep into the many admirable qualities but also pinpoint areas that have room for improvement.

🔊 Phenomenal Sound Quality and Clarity: The first time I connected my smartphone to the OontZ Angle 3 and played some tunes, I couldn't help but marvel at the depth of the sound. With 10 watts of audio power, the speaker projects crystal clear sound even at high volumes without any distortion. Whether I'm streaming classical music, hip-hop, or an intriguing podcast, the audio fidelity remains consistently impressive. The bass, often the Achilles heel for many portable speakers, is surprisingly robust, enriching my playlist with full, resonant low notes that never overpower the melody.

🌦 Robust Durability with IPX5 Rating: What caught my eye was the IPX5 water-resistant rating. I tested it out on a family beach day, and let's just say this little beast can take a splash and still belt out your favorite tunes like nothing happened. This feature makes it a perfect companion for outdoor adventures, bringing a newfound resilience to the world of portable speakers.

📱 Swift and Stable Connectivity: Compatibility and connectivity are the unsung heroes of any wireless device. The Bluetooth 5.0 technology ensures the OontZ Angle 3 pairs smoothly with all kinds of devices"”be it Android, iOS, Windows, or Mac. What's more, it maintains this connection tenaciously, making annoying dropouts a thing of the past.

🎨 Aesthetic and Functional Design: Beyond its robust engineering, the OontZ Angle 3 is a visual delight. Its sleek black body, complemented by discreet control buttons, is as functional as it is stylish. The design is intuitive, with the rubberized exterior not only providing an elegant aesthetic but also a comfortable grip, ensuring it won't easily tumble over if you're partying a little too hard.

🔋 Exceptional Battery Life: With its long-lasting battery, the OontZ Angle 3 pushes the boundaries of what portable speakers can achieve. I managed to get close to a full day of usage at moderate volume levels on a single charge. The freedom this affords you, especially when you're outdoors or away from a power source, is genuinely liberating.

However, to give a balanced view, it's only fair to bring up an area for potential enhancement:

🔘 Button Responsiveness: Though generally user-friendly, the tactile feedback on the control buttons could be improved. At times, they require a firm press to register, making me wonder if I've successfully adjusted the volume or skipped a track.

To encapsulate, the OontZ Angle 3 Bluetooth Speaker earns its 5-star rating without a sliver of doubt. Its minor quirks are inconsequential when stacked against its myriad of features and exceptional performance. With its mesmerizing audio quality, rugged durability, seamless connectivity, stylish design, and robust battery life, it stands head and shoulders above the competition.

So if you're looking for a reliable, feature-packed, and exceptional-sounding portable Bluetooth speaker, your search ends here. I wholeheartedly endorse the OontZ Angle 3. It promises an auditory journey that's rewarding, expansive, and full of surprises. And that, in essence, is the purest form of what music or any auditory experience should be"”an enriching journey that tantalizes the senses, one note at a time.

I hope this comprehensive review has been enlightening and helps you make an informed decision. Here's to elevating our lives with the power of sound, one beat, one note, and one song at a time. Thank you for taking the time to read, and may your life be a melody of beautiful experiences!

So I purchased the Top 4 speaker results on Amazon, this is the listing from Best to Worst:

Soundbox Pro, OontZ Angle 3, MusiBaby-M68,
Anker Soundcore

Here's the reasoning behind why:
$39 Soundbox Pro - 8.5/10
Had the best balance between bass and vocal clarity, and you could enhance the bass as well. Loudest volume, decent LEDs, battery life is pretty good, 3-6 hours based on volume. Solid purchase.

$24 OontZ Angle 3 - 8/10
This might be the biggest bang for your buck. Had the best vocal clarity of the 4, at the expense of bass, but the volume can go quite high, which could technically increase the bass. Battery hasn't died 4 days since I purchased and consistently used, turning on the device is quick and doesn't make weird noises like the rest. All for $24, definitely a steal atm.

"$23" MusiBaby-M68- 6/10
Product was $28 but was doing a $5 off promo. Has the most bass of the 4 and the voice is surprisingly clear, but the volume doesn't go very high, about 50-60% of the previous two

$24 Anker Soundcore - 5/10
Out of all the speakers, it's the most muffled, least bass, least voice clarity. Nothing particularly wrong with it, just better alternatives, as the result is extremely mediocre

I'm giving this 5 stars not because it's perfect, but in comparison to comparable products and prices. This review is for people looking to carry a speaker around. It is not ideal as a sound bar or semi-permanent desktop audio system because larger, more expensive, less-portable products will do better there.

Sorry to gush a little, but this will probably be helpful for people doing in-depth research like I did. The downside of this review is it's my first BlueTooth speaker. But I've been searching for the perfect self-powered auxiliary speaker for decades. I still have the old Radio Shack RCA 4x C powered speakers some will remember from the '80s. Those were surprisingly good: an MP3 speaker before MP3s existed, but the Achilles heel was the 4 C cells (and the high self-draining auto-off w/no hard switch), or I'd probably still be using them. The size of those RCA's was also comparable to a lot of brick-shaped modern Bluetooth speakers, which I think is too big for ultraportable use. I think the Angle3 is the best compromise out there right now for people who want to carry the speaker with them from room to room, but something quality enough for marathon listening of shows and books.

PROS

- DEDICATED VOLUME BUTTONS
(most BT speakers have annoying dual-use buttons where you have to press-and-hold the button to get to the volume--or no volume control at all. Having really quick volume control and still have pause/mute is really handy. You lose bluetooth track skip, but it' so worth it to me. Good choice design choice IMO, CSW!)

- SHAPE
(is there any other triangular shape out there? yet it really makes sense. rectangles/cubes/muffin shapes either project the sound straight up, or straight out. triangle design also stable and tip-resistant.)

- 18650 BATTERY INSIDE
(known capacity and output, more chance of good quality, easier to service, I like the way the designers were thinking. I haven't seen the innards of an Angle3 but a reviewer of the Angle2 Plus posted internals)

- OTHER SMART DESIGN TRAITS
(real screws, mostly logical hardware layout, and did I say 18650 battery which makes the 10 watts possible & believable; most units 3-7 watts. thank you Cambridge SoundWorks, for not gluing those rubber bumpers on. nice)

- PLAY/PAUSE BUTTON WORKS AS MUTE BUTTON IN AUX MODE
(useful when listening to live or streaming broadcasts where you can't fast-forward over commercials)

CONS & NEUTRAL

- Power button is too close to the connectors, and awkward to turn on. Hard to find with your fingers (or even eyes). Cambridge seems to be aware of this, so they put a decal of "POWER" with an arrow pointing to the button, tacitly admitting it's hard to find. You don't really have to worry about turning it off, so turning it on is not that big of a deal. Just more difficult if you have an aux cable attached. I think this is to make the soft switch hard to accidentally turn the unit on, and in that they succeeded. The original Angle had a real hard/mechanical power switch which is nice, but I am also enjoying the convenient 10-min(?) auto-off (and it's nice that it doesn't make a noise when it turns off, if you're asleep). I wish I knew the soft-off power consumption. Considering the 18650 cannot be swapped from a battery hatch (I REALLY wish it were), I don't want it to be dead when I go to grab it. An 18650 battery compartment would make soft-off power draw partly moot as I could remove the battery for storage.

- So not a con, but a Wish List for future version: I'd really love to see Cambridge migrate to an 18650 which is replaceable like a normal AA battery, so I could choose my own batteries, charge them externally, and replace them when they drain down. As a flashlight guy, I have a ton of quality 18650s lying around.. modern electronics are screaming out to have 18650 cells be the next AA. (Cambridge, make sure your battery compartment can fit protected cells, if you do this! Take a look at some of the cheap MiFine 18650-powered radios sold here. This needs to be a trend.)

- After using it, I see that the triangular design and all-black color scheme makes it hard to figure out the orientation at a glance: which side fires the speakers? Which side has the controls? In Bluetooth mode, you can actually have it perfectly facing towards you, yet it's still upside-down. That's not a problem till you go to push a button. Which side is it on? Or your finger's on the correct side, the buttons may not where your finger expects them. This makes a good case for one of the colored versions, but I devices like this to not catch the eye. I may use some fingernail paint or something to mark the top of the triangle, perhaps just on one side to also note which side has the buttons.

- Nitpicking, but kind of a dirt magnet. If these are my biggest issues with it, I'm ecstatic. The rubber side covers could probably be removed and washed if desired.

A NOTE ON SOUND
Most readers just want to know about "the sound", but there's much more to a bluetooth speaker, so I've chosen to focus more on those other things. I'll get "the sound" part out of he way now. What I write may not be applicable for most, because I'm an audiophile, and most stuff sounds like crap to me, compared to the glowing reviews I read. I'm disappointed by a lot of speaker systems which most people go wild about. Then again, the setups I've settled with would be extreme for most people. I really think most Americans have substantial hearing damage. I know expectations and understanding limitations is important. In that light: the Angle3 (to me) did not quite live up to the reviewers' claims for music, but it did live up to hopes in VOLUME, and for most hearing-damaged people, quality=quantity. I haven't tested its upper limit with music, but with speech, yeah it can go louder than I need or even want. Cranking it outside, yeah you could get your neighbors' attention. Quality-wise, it sound quite excellent for speech and occasional bumper music, which is mostly what I'll use it for. But quality sound does not equal high volume, and if this is the best-sounding speaker system you have, I feel bad for you. But for many, this will be. The laws of physics put some limitations on a box this small, but considering that and Amazon's price, it does a really admirable job. The passive bass radiator does actually do something, too. A comparison: to my memory, the sound is not quite as good as 'portable' Panasonic dual cassette-radio smaller boombox I used a lot in the 1990s, but that thing was much bigger comparatively. It also had dual 4-inch speakers, and was always AC-powered--not really portable, and if it was, took C cells, making it not really a fair comparison. So considering the limitations and cost of the Angle3, nearly matching that sound quality in something this size is exciting, because it's SO DANG USEFUL. I've used it so much in the first week, it doesn't look new anymore.

CONSLUSION
This little is I think the best compromise of size, shape, sound, and price. It's big enough to give volume that won't disappoint except for truly extreme needs (like the review by the UPS driver in a noisy truck going at highway speeds) or disproportionate expectations, but it's small enough to take with you from room to room as it plays. I sit it on my chest in bed, or beside me; it's great. Without having an opportunity to hear other current/popular BT speakers (and online video reviews with sound only get you so far), I still think I made the right decision. I'm loving the Angle3, and using it a lot. There are a ton of good choices at prices more affordable than ever, so making up my mind was a painful, lengthy decision, as if I'm going to buy several, I might as well buy one that's several times the cost of this--so I wanted to only buy one, but make it a good choice. I would say the loudness is more impressive than the sound quality. And I didn't buy it to blast anything, but the sound quality is quite nice in this size, and I'm sure there's nothing in this SIZE and price range which would impress me more. If I needed more of a desktop-type speaker, I'd definitely go with a bigger one, like the Denon brand--but I wanted SMALL (I actually was originally shopping for smaller), with good sound, and loudness when I need it occasionally. I've found the form factor very convenient. I'm not jonesing for an upgrade. But if Cambridge managed to reduce the size a bit yet again, while still increasing sound quality and not compromising on volume, AND introduced a battery compartment for removable 18650 batteries? Yeah, I'd bite.

I cut out a lot of writing for this review, for the smartphone generation. I'm thinking about posting a fuller review elsewhere for people who'r really into doing research. If requested, I can share more details. If you have questions, feel free to ask. If you're handy and adventurous, open one up and help the community with some pics of guts, if I don't get to it first. Frankly, aux speakers sucked until Bluetooth speakers hit the market, but lithium batteries is more the reason behind it, though economies of scale was the other. All my life I've scrounged for a decent aux-input speaker with no good answers--and suddenly, online stores are overflowing with an amazing variety of high-quality, low-cost options. The hardest part was settling on one! I don't get it! Even in the past 5 years, the quality and options have gone up immensely, and seems to keep going. The Golden Age of aux speakers?
