Great Everyday Earbuds – Lightweight, Comfortable, and Reliable
I've been using these earbuds for about 10 months now, and out of all the ones I've tried over the years, this is definitely the best. They're incredibly lightweight and comfortable—most of the time, I can barely feel them in my ears. The tactile buttons are a great touch, making them easy to control without the frustration that sometimes comes with touch-sensitive ones. The sound quality is very good, with clear mids and highs, though you shouldn’t expect heavy bass. For most types of listening—music, podcasts, and calls—they perform really well. Battery life is more than adequate for above-average daily use. I rarely find myself needing to recharge them unexpectedly. I especially recommend these for indoor use, where they truly shine. They’re not ideal for outdoor environments with a lot of background noise, as the noise isolation is limited.

Awesome, except one doesn't work anymore after 9 months
Update- I received a full refund and will purchase these same earbuds again. Because I really do love them! I LOVE these earbuds. I love the open design, I think the sound is great for my purposes (I'm not a musician/audiophile). I also think they are incredibly comfortable. I deeply dislike earbuds in my ear canal, and the over the ear types get sore after a while. These are absolutely perfect. However, after about 9 months of use, the left earbud has lost almost all sound. I just contacted the company. If they replace my earbud or otherwise remedy the problem, I will change my rating back to 5 stars.

Good sound and quality, ok-ish battery life
Solid sound quality for open ear earbuds, volume boost with soundcore software helps in noisy environments More comfortable than the c30i, no sharp edges to irritate spots on the ears plus a semi flexible link between back and front of the earbuds Battery life leaves a lot to be desired compared to theire other earbuds including the c30i, will not make it through a 12hr work day but does seem to last for an 8hr day Easy to connect and supports dual connection for 2 devices Easy to use and has tactile buttons

Soundcore c40i - Amazing comfortable ear buds!
Beautiful sound, catch these at this reasonable price before they go back up. These ear clip buds punch WAY above their weight and the added app allows greater customization of your sound profile. You will love these Soundcore c40i earphones!

Worst function, quality and service.
Purchased Soundcore c40i in Jan 2025. Within 6 months it keeps giving me headaches. Once it connects to phone it wont disconnect even when both earphones are put back into the case and closed. So the phone keeps sending voices to Soundcore earphones and won’t link to other Bluetooth devices. It’s very annoying when you get off work, restore the phone and get in your car trying to make a phone call from CarPlay or car Bluetooth. The earphone wont disconnect until your phone call goes thru and you cant hear the person you’re calling and they can’t hear you either then you realize you need to disconnect the earphone manually. Imagine this happens on daily basis. This is not only annoying but also killing the battery fast. Because it basically connects to your phone 24 hrs. Whenever you play music or videos you hear your music or video comes out of the earphone case. That’s right, the earphone still plays voices when they are both in the case. Maybe it’s because of the “always on“ connection, the ear phone goes bad fast too. The left side earphone cannot connect anymore after around 5-6 months. When I sent warranty request thru Soundcore app it gave me a hard time too. It keeps loading pic of receipt and never sent out. After weeks of trying the warranty claim finally sent. But I never heard from soundcore even the app told me they will get back with me within 24 hrs.

Great until they stop working after too little time
I have small ear canals so I was interested in these. The fit on the outside of the ear is great and they don't hurt my ear canals. The sound is pretty good too -- I definitely noticed some things in songs I've listened to a million times but didn't hear before on crappy earphones. HOWEVER -- they stopped working after 6 months of light use. The right earbud has gone completely kaput - no sound at all. In the app, it can only access the left earbud and so can't update the firmware or reset. I use them maybe 3 hours a week at most, and after 6 months that gives me less than 100 hours of usage. Which at the price I paid is close to $1 per hour of listening time. Definitely not cost-effective!! Amended to 3 stars. I submitted a warranty claim and I mailed back the broken set at their expense and got a brand new set in the mail a week later. I appreciate the good warranty support !

Great product
Excellent fit and feel. They don't fall off my ears when moving around a lot. Highly responsive (almost overly sensitive) button controls on the earbuds themselves. Because they do not "plug" the ear canal like non-clip-ons, the distance between the ear canal and the speakers makes it so there is little noise cancellation and the bass quality is reduced. I purchased these to exercise and work, so I need to be aware of my surroundings regardless. For the price point and type of earbuds these are, five stars.

Best of open ears
I tried bose, shokz and all anker open ears. C40i is the best one. Mic quality, sound quality, no drops during heavy workout.

Outstanding view and manufacturing quality. Nice charging box. Physical buttons works better than sensor. I have B&O, AirPods Pro, Shokz all mentioned above sounds better but it much costlier . Mic quality is better than B&O and AirPods Pro. Overall user experience is great I can wear it and hear everything around like using Shokz but these are more comfortable to use at home. I would definitely recommend it to buy for the price less $50! It produces some pressure to my ears but I was able to get used to this. Sound quality is expected for the price. I am fully satisfied with it but it one of the worst sounds I have ever heard. But i am comparing it to much more expensive products. So don’t think, just buy ;) It is good for sport activities and relaxing at the beach. Bluetooth connection is stable and long ranged. It has application to setup effects and reassign buttons.

Fantastic headset. Mainly use it for phone calls. Fit is very comfortable. Call and overall sound quality is excellent. Battery lasts for an entire day. Would have been great if the button was located more to the outside of the bud, but understandably an issue given that is where the bend is. Highly recommended overall.

Excellent pour le prix.

I decided to try open earbuds, did my research, landed on these. The clear ones look pretty cool and fit right out of the box. They stay secure, I can feel them at first, but not as uncomfortable as in ear buds. After a while I get used to it and can almost forget I'm wearing them. The app from Play store is polished. The sound actually surprised me. I was prepared to be underwhelmed compared to in ear type. The bass/low end is definitely weaker but the separation and soundstage are pretty nice. So far, I'm impressed. It's great to be aware of your surroundings, bike riding, shopping, walks, there are many use cases, even in the dentist chair.
