    • My Favorite Earbuds and Excellent Customer Service
Color: Black
There’s a lot to like about these earbuds. In fact I purchased 2 pairs of A40. Great fit and comfort, good battery life, great sound, and their app is remarkable. It lets you set touch actions for volume, stop/start, skip, etc (single tap, double tap, triple tap and long tap controls for each earbud) and lets you endlessly calibrate the sound to get the most out of what you’re listening to. I typically shut off single tap to prevent inadvertent touches. I’ve tried at least 10 different earbud brands and these are definitely the best. My only issue is that they seem to last 12 months before I experience syncing issues, granted I wear them nearly daily and sync constantly between 3 devices. The main syncing issue is failure to disconnect from my phone after I put them in the case and shut the lid. Maybe I need to clean the contacts better, but I feel like they get a bit finicky. It can be annoying to have to manually disconnect them from my phone to unpair them. I can say that their customer service is legit and took care of me quickly after one of my pairs stopped working altogether after a year. They communicated via email promptly and after concluding they had in fact stopped working, they sent me a new pair. I was surprised that In 2026 there are still companies that care about their customers. Bravo. I have purchased at least 6 other Soundcore devices for my 3 daughters and my wife, headphones and earbuds. They are definitely the best sound for the money with solid noise canceling. Plus their app and customer service make it a no brainer for me. ... 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

    • Awesome price, premium features, not the best for exercise
Color: Blue
Grab these at the discounted price for the ultimate bang for your buck! I purchased these for about 50 bucks including tax while they were on offer and its the best purchase I've made in a while. Sound quality is fantastic for its small size. Flawless connectivity between my MacBook and Android phone. Battery life is awesome too. I usually only wear a single bud on one ear and it will last me my full 8 hours of work. If one bud dies, you still have the other and I'm confident you could keep switching back and forth between buds if you happen to need more than 8 hours of listening time. The earbuds are comfortable enough to wear all day, however they aren't the best for exercise or working out. I bike a lot and they are absolutely fine for that, but when I go lift weights, they have fallen out of my ears various times. I scrunch my face and I guess that slowly wiggles the buds out of my ears. This is the only reason I'm giving it 4 stars, if the buds stayed in my ears during exercise these would be 5/5. The active noise canceling is awesome, I have a small server rack and AC and a loud fridge in my room and the noise cancelling really does a great job of getting rid of 99% of those noises, this allows me to set the music volume very low if I need to focus, or loud to enjoy the music more deeply. I've had other Soundcore products and they've been fantastic. I've had these ear buds for a few months and they've been a very great purchase with no regrets. If you listen to music everyday, but dont want to spend 100 dollars on some earbuds, these have similar premium features to Apple's earbuds for a quarter of the price when these are on a discount. Even without the discount, if I had more disposable income these would be a great purchase as well. ... show more
