Wow! STEREO Pairing AND GREAT Sound! UPDATE: 6-12-23
Update: 6-12-23 These are still going strong! Just used one of them as a phone speaker and it worked great. Clear with no echo. Has not lost sound quality or battery life. I cannot stress enough: these sound waaay better than their price suggests. Get a pair of them and pair them blue tooth, and you will be very pleased. The bass is so good that you cannot place these speakers where loose objects are or they will make them vibrate. These little speakers will also walk off a shelf due to the bass they put out so make sure there is a ledge or something to keep them from falling off a shelf or rail on your patio. Updated 5-4-19: I returned the Anker Soundcore II due to the speaker losing bass and the power button went wonky. Anker did step up and sent me FOR FREE an Anker SoundCore Boost 20W Bluetooth Speaker with BassUp Techno! These sound way better than a single Oontz Angle 3 Ultra, way better. But, I would take a pair of the OontZ speakers and listen in stereo. You can get 2 Oontz Angle 3 Ultars for the price of one Anker. The Anker speaker rocks, but stereo is much better listening experience. Oh, Anker upgraded my speaker and honored the warranty even though 30 day window had passed. CHANGES TO ORIGINAL REVIEW: 1. The OontZ Angle 3 Ultra (oa3u) sounds better in bass and full sound than the Anker Soundcore II (ASII). Not as clear in the highs but better overall sound 2. Higher volumes, the OAS3U beats the ASII. 3. While not suited for a outdoor party filled with drinking friends who are talking loudly, they are more than adequate for a family gathering where people are talking but not drunk. More for patio than yard use. 4. When used with jetAudio EQ, these little speakers sound extremely good and the bass moves up, while not distorting. I listened to the following songs and compared these OA3U speakers with the ASII: Damian Marley - All Night; Depeche Mode - Lie To Me; Supertramp - Oh Darling; Level 42 - Something About You. Each of therse songs NEED to have bass and the OA3U won when playing each of these songs. Still like the ASII, but the OA3U are better. Review is for: OontZ Angle 3 Ultra (OA3U)Dual Portable Bluetooth Speaker I wanted to let those searching for a great speaker for a budget price and good sound, you have found it. I have tried, used and enjoyed the following speakers: -Harmon-Kardan Onyx Studio II (pair) -JBL: Clip; Clip+; Flip; Flip II; Charge -LG PK3 -Anker Soundcore II -Aomais Sport II Portable 4.0 These pair easily, but not intuitively. Read the pages 14-15 of the getting started manual and you are set. They even play a stored sound file that tells you which is the left and right channel. It plays in true stereo. For under a $75 for a pair of good BT speakers, that PAIR in true stereo, pump out good (not great) bass and are loud, this purchase is a no brainer. Out of a 4 Class system defined by me: -Class 1: HK Onyx Studio II -Class 2: JLB Charge II and subsequent models; OontZ Angle 3XL ULTRA; LG PK3 -Class 3: Flip-Flip X, Soundcore II, Oontz Angle Ultra III -Class 4: JBL Clip and similar pocket speakers. FOR ITS CLASS, this is at the top! In fact I am unsure if these speakers should move up a class when paired! I tried the Aomais brand speakers but they were too weak on bass, thoguh they are also true stereo. The Soundcore II actually sounds the best of Class 3, but it does not pair to play stereo. I would have gone with a pair of Anker Soundcore II if they played in true stereo. The SC II handles bass the best, and rival or beat Bose Soundlink II Mini. If you are going with one speaker under $50 and do not care about playing in stereo, the Anker Soundcore II beats the OA3U across the board. How? The bass is better, the rest is quality highs and lows and MOST of the volume range. The OA3U remain paired to each other even after turned off and then turned back on. In fact, you should disconnect BT connection if you use several devices with the OA3U or you will will have to go find the last device you paired them with and disconnect the BT. These pair with only one device at a time. Listening to "Holding Back the Years" - Simply Red. Without at least some decent bass this song would be ruined. Also listened to "How 'Bout Us" - Champaign and "I Wanna get Next to You" - Rose Royce. All three of these songs require good bass to do them justice and these OA3U speakers do them justice. Whoa, Rush "Tom Sawyer" now playing. Decent bass for this song but this type of song needs the volume and bass of the HK Onyx Studio II CRANKED up. However, the little OA3U speakers are holding their own. "Black" - Pearl Jam, sounding good! Damn good and I have the speakers at about 65% ZERO distortion. Finally, these are NOT outdoor party, fill the yard with sound and drown out the guests. These are great indoor speakers (that can be used outdoors thanks to IPX rating) and are more than adequate for a good sized living room. People expect whichever speaker they are buying to be light, have a 24 hour battery and pump out at night club quality bass for less than $100, ain't happening. That said, these are way above their pay grade.

STUPENDOUS SPEAKERS!!!
I've been using these speakers for about two weeks or so now and I gotta say without out a shadow of a doubt these speakers deliver quality sound at such an affordable deal. I paid 70 bucks for these on sale and the dual function is seamless and connects automatically now when I turn them both on. The app is a huge flop in my opinion but basic use may be necessary for firmware updates and such but I wouldn't use the EQ on it alone. I use a third party EQ app or you can use EQ from spotify (in app) and really unlock the potential from these speakers. If you still want to up the treble or bass over all after getting the EQ you can but not specific frequency via the OontZ app EQ. I play a huge variety of music from these, I enjoy bass heavy,distortion heavy, and techno/electronic music mainly such as Infected Mushroom and Daft punk but it plays rock and pop super crisp and clean such as Spilly Cave, Tame Impala, Danzig,Ac/DC, etc. If you're in the market for good well-rounded speakers this is the set to get.

Perfect for work
Had the one smaller than this one before, and it lasted me 7 years so I decided to upgrade to this set of 2. Just as durable as the smaller one, definitely louder and sounds great with them paired for stereo sound. I recommend downloading the app that goes with it, you can mess with EQ settings which helps with some of those songs that sound a little too quiet. Battery lasts about 8 hours before it hits low battery at about 30% which it still functions, but cuts the volume to preserve battery life. Not too much bigger than its smaller counterpart, so portability will not change all that much. Comes with the type C upgrade. I’d say this is PERFECT for work, small parties, etc but if you want to blast it for a big party with a crowd, you’ll want the bigger version.

Impressive for the price
These speakers are quite impressive for the price. I purchased these to be used in a large room for a holiday party and they performed well. Filled the room with pretty good sound, clear with no distortion even turned up high. The battery life seems to be good. I ran them 6 straight hours with no isuues. They were super easy to connect to my Fire Tablet and to pair to each other. The bass is not bad but don't expect them to be as good as higher end wireless speakers like Bose. But for the price, they fit the bill.

Amazing sound
This is the most amazing product. True stereo separation and such dynamic bass and highs. I would recommend this product to anyone that is a true music affectationato. Its portable and you can transform any space into an amazing sound experience. Never thought this product was that good. It blows my experience away. Listening to this product on my front porch. And honestly. It sounds like I am in a concert. If you are looking for a portable stereo experience. This is your product. Honestly the highs and the Dynamic range is off the charts. So damn happy with this. Listening on my front porch and I feel like I am front of a symphony orchestra. The most amazing sound for the money. If you are trying to make a decision to order these. I can promise you that it will be the best decision you could make. Orchestral sound that is second to none. An awesome product for the money

Incredible sound and value
Well I am stunned at the sound and ease of use, especially given the very reasonable price. Setup was super easy, works in nice clear stereo at 50 feet from iPhone. Had struggled with AR Santa Clara stereo Bluetooth speakers, which were double the price of these very neat, compact and punchy speakers.

I bought these speakers to use to teach yoga classes outside in the summer and they have been fantastic. The sound is clear and crisp and they have a range of 100 feet. It's super easy to pair both speakers making the sound even better. Great value for your money.

Fabulous product. The ability to play left and right channels, using the 2 speakers creates an immersive stereo sound. They can be placed anywhere for whatever you are doing. With the app, you can adjust volume of each one, so the speakers don’t need to be placed equal distances apart from you. Also, they upgraded the charging port to USB type C. I previously had an older generation model with micro USB, it got bent up, and couldn’t be repaired. This 4th generation model is great. I’m a bit of an audiophile, and am impressed with the sound; good bass, mid and treble. The stereo setup, using paired speakers, blows other Bluetooth speakers away. I highly recommend it.

I got this as a Christmas gift and quite content with it! Love how I have a left and right speaker that easily connects to my tv :)

Finding a speaker with a built-in mic is hard. Finding one with a good speaker is even harder. I bought 2 sets (4 speakers) for home and office. Apart from music, I use them for my Zoom meetings… totally hands-free.

Great sounding speakers, I was hoping for something a bit louder.
