Color: Black
Balanced sound. Decent ANC. These things are excellent for the price. They may not be quite as good as others that cost twice as much, but they're close enough that I don't feel like I could justify spending the money for such a small improvement. They're comfortable and stay in my ear very well. Noise canceling is probably the only area where they fall noticeably short of more expensive options. It's good, but still allows more sound in than some people would prefer. I don't personally need to shut out the world, just quiet it down. So it's not an issue for me. Anker has proved that it's entirely possible to produce good stuff without the high price tag. I've owned several of their products, and I've always felt like I got good value for my money. ... show more

    • Really Excellent Audio Quality and Noise-Cancelling in a Well-Priced Product
Color: Black
The noise-cancelling and sound quality are top-notch - really excellent. The Space A40 is one of the best wireless ANC models offered today and well worth the price. Set-up is easy. They stick in your ears pretty well when doing fairly placid exercise like hiking, walking, yoga, weightlifting - might not always stay in place while doing competitive team sports with a lot of rough movement, potential collisions with other athletes and so on. They can handle a bit of water splashing in their direction but I noticed the sound quality is reduced for a while when water gets into the space between the bud tip and your ear - until you work the water out of the space. ... show more

    • Great overall earbud. But expected better mic quality
Color: Black
When it comes to soundcore I’ve always loved the clear sound from their headphones and with the app, you can customize the way they sound. With this particular pair though, the custom eq fell short when it came to customization the sound. There was little to no difference no matter what I did in the app. For the fit, it’s a little bulky and larger than expected but with the extra ear tips, they can definitely stay put. Pro tip, if you struggle keeping earbuds in your ears, try true wireless memory foam tips. They expand with the heat of your body so they tend to grip more, plus creates a better noise isolation, which would pair perfectly with the noise cancellation for overall immersion. Setting these up are super easy with android and with iOS it’s the typical process with any none Apple headphones. I’m typically not a fan of touch controls on earbuds but they’re actually not bad. Not overly sensitive or a need of pressing so much to make a command. Noise cancellation, was what I expected, still very good for the cost. Mic, now I do understand with any true wireless headphones, earbuds, sometimes you do need to speak a bit louder so that the mics can pick your voice up, with these you can speak normally and the caller on the other line can hear you. The part where I was disappointed with is, I can be heard easily but it sounds terrible. Like when you speak on speaker phone and you’re just too close to the mic. That’s the best way I can explain how it sounds. Overall I really like these, I do recommend to buy, especially for the price point. High quality overall but can’t have everything when you’re budgeting. ... show more

    • 4.8 out of 5 only cuz the NC cuts out if the sound is too loud.
Color: Blue
For 45$ u can’t beat these ear buds, solid 10 hour battery life about 8 hours with noise canceling on the sound quality and bass is actually impressive, just as good as 200$ JBL’s. Noise canceling is good but if ur around something a little to loud the noise canceling cuts out, honestly that’s my only complaint. They are probably the most comfortable earbuds I’ve had and the silicone part that goes in ur ear is even designed well, connects everytime, kind of wish it had a light on the bud so I can tell if it happens to not connect for some reason but I would recommend these ear buds to anyone. I pretty much exclusively got JBL’s before these ear buds and I now have a new favorite brand. ... show more

    • Almost a year with these buds - SPECTACULAR!
Color: White
Final update - the right earbud issue has yet to repeat, so that's not an issue. As I've said, I have four other top end earbuds, and the only pair I use is the Soundcore A40. We have a little land and a John Deere Z920M zero turn, and its loud. My neighbors all have the same mower, and all wear headsets. I now won't mow without my A40's, as the noise cancelling is even better than my 1 month old top end hearing aids (thanks VA). The sound is not like you're sitting in a studio listening to an album on a top end everything audio, but nothing is, so when people try comparing buds to studio headsets, I just smile. The sound is crazy good for a couple of marble sized devices that connect via a rf signal. Darn amazing. Update - I submitted a warranty claim, due to the right earbud not being active when I started this morning, but I decided to put them back into the charge case for a few minutes and it came to life. Here's to hoping this is not a new trend? Still love their sound quality, and general fitment. I have noticed that they have started to come loose when I'm bent over working in the heat. I've been tempted a couple times to buy new buds, but these are still very hard to beat. Over the last two months I've tried several earbud, all were horrible failures. These are different. Shortly after I got them I headed from N. FL to Delta Junction AK. So 9 total hours in the air both directions. While there I spent 5+ hours a day running a chainsaw, a stump grinder, and a commercial wood chipper, all while using the noise cancellation (N/C). I never ran out of battery life while running N/C, although once I left the first leg of my flights, I did put them back in the case, so each leg they were returned to full charge. Only once did I have one come lose from my right ear, and it did not fall out. Before I left I'd use them to run my John Deere commercial mower for the two hours it takes to mow the yard, and they were awesome at cutting out motor noise. Wear - With the correct tips they work flawlessly. They have a fit process called Real Ear ID (or something like that). The testing will determine the best fit and seal by running those tonal sounds you're used to in hearing test booths. I was never able to get a passed or perfect fit according to the test, and I did try three sets of the foam tips (these did not work in my ears, and they did not allow the buds to charge in the case). As I said they stay in your ears. Charging - The case is small and give you a full charge in well under an hour. There are only 3 led charge indicator lights, and I've never had less than 3 lights. The case also has the USB-C type charging port, unlike half of the other buds I tried, which still had micro USB. There are no good case covers that I found on Amazon, but I bought a soft case cover and it works ok, where I'd rather have a hard cover. Touch control - the app allows you to change the function of single, double, triple touch, and long hold. The touch is responsive, and accurate. Wear - Possibly a kind of repeat, as I've discussed fit, but I wanted to cover comfort. I do not get wear fatigue. Sound and volume - The sound is easily as good as my Samsung Ear Buds Pro with much better battery life. Volume seems to be a problem with most earbuds, but not these. I'm older with hearing loss, and like to listen to my music louder than is comfortable for most. I end up around 45% of volume for regular listening, and around 70% they become too loud, but the sound is still clear and crisp. The App - It is simple, but complete, with EQ function. I've finally found a set that I'll keep. ... show more

    • Yes, they fall out of your ear
Color: Black
So I can put these in my ear and shake my head around and they stay put and feel secure. Then, randomly, later on I can be just standing and talking to someone, with little to no head movement and an earpiece can just POP out striking the concrete or tile and ricochet under the sink into the floor drain, for example. The ambient hearing setting is pretty cool, it almost works. I mean it DOES work, but it's not the same as having nothing in your ears, it's more like having only a partially effective plug in your ear. I could still hear people speaking to me, but they were muffled and harder to hear than normal. Distance sounds were much harder to hear than nearby sounds. On noise reduction mode it worked like a normal earbud and reduced outside noise. These have been the best at phone calls that I have tried lately. They quit making the bcs700 neckband which worked great for phone calls (well, worked okay, which is better than most), so I've been experimenting with all kinds of replacement ideas. These little inside the ear earbuds are comfortable, the volume is great, the caller can hear me over the background noise around me.. which is something 99% of these things fail to achieve. They're small and their case is small, so it's not as inconvenient to take them out and put them in my shirt pocket or their case if I need to talk to someone without my ears plugged. They're tough, I guess, because one of them has hit the concrete twice, the tile once, and they other hit the tile once, and so far after 1 day they haven't shattered. That's going to be a problem though. I can't have them randomly POP-ing out of my ear to go skittering off under cabinets or whatever, especially not on construction sites where I work. They'll end up in wet cement, or down a floor drain, or buried in sawdust or something one of these times. The good: comfortable, lightweight, long-lasting (8 hrs or more), good volume, almost let's you hear ambient noises when set to that function. plus they have a cool app! The best part of the whole thing is that your caller can hear you, even in a noisy work van with tools and equipment rattling. Even with the AC on and blowing at your face. Even on a jobsite where various people are running power tools in the background. That's Fracking amazing. The bad: I never could figure out where the "button" is or what makes it think there has been a press or double press. Somewhere on this little bud is a "button" that does different functions depending on if I press, double press, or long press. I assumed it would be the big flat round piece with the logo on it, but there's nothing that gives you a tactile feedback and the device doesn't always react if I press there. sometimes it does, but sometimes it reacts as if I pressed there when I'm touching only the edge.. so I'm not sure. I'm sure it says in the manual, but I'm sure I can figure this out on my own eventually without having to resort to reading the manual!! I'm not a nerd!!! Another bad thing: They randomly POP out of your ear, especially if you happen to be over tile or concrete. If you carry a flashlight in your tool bag, that can help you spot them if they end up in a floor drain or wedged in the dark recesses of a bottle caps, broken glass, in a sticky black patch of goo that was probably formed from old beer and soda, under the sink at the bar where you are working. These might be more suited to a carpeted environment so they take less impact damage. I kind of wish I had bought some with an ear-hook so that if the bud part popped out at least it wouldn't fall to the ground. I'm going to try these another day or two, try some different eartips and see if I can reduce the POPout. ... show more

    • honestly amazing
Color: Purple
This is the greatest budget earbuds I’ve genuinely ever used. It’s simple to use but you can do so much more with the app, it’s honestly really impressive how many features are in the software. The greatest feature of them all is being able to pair to two devices at once. I never knew how much I needed this, but it’s so convenient when im switching from my phone to laptop. I don’t have to worry at all about disconnecting a reconnecting my device. The box comes with different sizes of eartips, which is really nice. You can adjust a lot of the things in the app which is really convenient. I like how intuitive it is. The material of it feels like good quality plastic, and it’s really smooth. The buttons are not physical buttons, and you get no physical feedback, but they work great. The sound is also high quality, and the noise cancellation works really well when commuting. It’s honestly really impressive you get all these features for such a low price ... show more

    • Nice but disappointing noise cancellation and loud battery warning
Color: White
Great earphones but not for sleeping or serious noise cancellation. Soundcore makes sleep earbuds, I know, but they were much more expensive so I tried these first. The sound was great. Wonderful fit and they come with different sizes of ear tips. Easy to pair with my phone. All great until the two things I wanted them for: noise cancellation and streaming audiobooks while I sleep (the only magic cure for my insomnia). The earbuds claim 98% noise blocking. I could still hear all kinds of noises: street sounds, neighbor dogs, regular talking, the AC that I was desperately hoping to block. Noise was less but like 40% less, at most. I tried all the methods suggested to make cancellation better. Disappointing, especially when I tried my husband's Bose earbuds and no sound got through. I might have lived with this but the battery didn't last through the night in noise cancellation mode and bellowed "low battery, " seemingly at a higher volume. There's no way to turn this off?!? Come on! Even if I weren't trying to sleep I don't want earbuds yelling at me. Anyway...for regular, non-sleep uses they're great and you'll probably like them. I am grateful that these could be easily returned. ... show more
