  • Wow! STEREO Pairing AND GREAT Sound! UPDATE: 6-12-23
Color: Black-Dual
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. ... show more

  • STUPENDOUS SPEAKERS!!!
Color: Black-Dual
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. ... show more

  • Amazing sound
Color: Black-Dual
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 ... show more

  • Solved my issues with getting stereo sound out of Amazon Echo Dots
Color: Black-Dual
Edit: Took away a star, but this will only affect those with very sensitive ears. I can hear the faintest of electrical beeping noises coming from these speakers (even when nothing is playing), and it's just barely audible. Most people won't notice it at all, but it's starting to drive me bonkers when I notice it. I'm probably going to have to get a higher quality set of speakers to replace these eventually. I have been trying to enjoy a pair of Amazon Echo Dots working together in stereo for about a year now, but they always seem to have issues (Alexa would respond only out of one speaker, sometimes it would work for a day or two but then only one speaker would play music, music would spontaneously stop playing, etc). Amazon's system for this is just awkward and unreliable, so I figured I'd try setting up a pair of bluetooth speakers to one Echo instead and bought this product. The instructions were clear, with specific examples for pairing to Echo Dots and other devices from various companies, and after not much fuss, everything was set up and working perfectly. Sound quality is better than the Echo Dot (4th Gen), and every single issue I used to have with stereo playback has been resolved. I obviously bought the bundle with two speakers and getting them to work together was as simple as pairing one to the Echo, and then holding down a button to get the other speaker to pair wirelessly. These speakers have improved my Echo experience in every way. My only complaint is that the speakers are powered by USB and come with very short cords (about two feet long, USB-C on one end, 2.0 or 3.0 on the other) and do not include any type of wall connector. You may need to consider purchasing wires and/or USB power ports or adapters depending on your setup. Overall, highly recommended! If you're trying to do what I did, I say forego the more expensive Echo products and instead buy a simple Echo Flex to pair with these speakers. You'll do a lot better than you would with a pair of Dots. ... show more
