My favorite headphones for doing things in. I forget I'm wearing these. They're so comfy and actually do have quite a bit of bass. Even the deep sub-bass in deep house is still there. I can't even believe that I can listen to the very bass focused music I like with these. They're missing that bit of growl that super deep bass has. These are definitely not as thick or rich sounding, can even be a little sharper sounding than the Bose QC 35 ii I have. To be expected. These sound more like standing in a really big room listening to music. You're not close to the music but it feels expansive and light especially since you can feel and hear your surroundings and you don't feel plugged up by over the ear headphones or earbuds. (They don't give the sound of an echo but some things feel like the sound is coming from all around you, which is delightful. You can turn on the EQ to"3D surround" and that's kind of echo-y and even more surrounding you, though I don't prefer that setting.) Before these I was practically living in my Bose QC 35 ii over ear headphones and now I'm not often tempted to put the Bose on. Bought them for audiobooks, stayed for music. I even thought that I love to live in noise cancelling every minute of my day, but it turns out that when ambient sound isn't distorted by earbuds and I have lovely music or books perfectly and comfortably in my ears, I prefer these to noise cancelling. I am a person who is quite irritated by bad sounds (dishes clanking, my electric toothbrush, cars driving, etc). I thought I liked that disconnected feeling you can get listening in noise cancelling, but it turns out that it's really nice to feel more in the real world while I listen to things. I can also put the sound to a level where I have some background beats/tunes and still listen to birds and the river. So lovely. They've been on many walks and hikes. I've jogged a bit with them in, washed dishes, put shirts over my head, and put on glasses and masks and hats. They haven't fallen out once. I was concerned that a lot of these type can't be turned on without their case so I'd always have to bring the case. Nope. It seems that it will stay in standby mode even if when it's not connected to anything for hours, and will still be on and ready to go when I reconnect the device (phone usually or my garmin watch). I have worn them literally all day most days since I've received them. The battery easily lasts the day, though sometimes I am not sending sound through them. Most of the time I'm on multiple hour calls and listening to music or audiobooks constantly, and only charging while I sleep. People report that my mic sounds very good. There are a few YouTube videos about this, if you're interested. My ears were a little bit sore on day 1 and 2 but I think it was because I was messing with the position and pulling them on and off frequently and incorrectly. It's worth sliding them up the ear before you take them on and actually putting them on up there before sliding them in place. You'll get used to it quickly and it's easy to find the sweet spot in your ear that sounds best and then just always put them there. They feel really light once you have them on. I have had 2 pairs of bone conduction headphones (one was the Shockz open move) that were so hard to wear with a hat, sunglasses, and a mask. Even without all the other stuff near my ears, I would always need to reposition those. These are just chilling there in place, not pushing my ears outward like the shockz. I'm pretty sure these also sound quite a bit better, and still sound great when they're not positioned perfectly.

These are the best fit for someone who also wears glasses and has hair. I can wear them during exercise no problem, no dropping out of my years. I have pretty sensitive ears which is why I don't want something IN my ear. I can wear these for about 4 hours before they begin to slightly irritate my ears, but this is very minor and probably peculiar to your ear shape. Sound quality (for both audio and calls) and battery life are great, and I really appreciate the fact that I can charge the case while I wear the buds. The feature that automatically pauses audio when you put them back in their case is also super-convenient. I like the small size of this model's case, which is about the size of toothfloss. The price is fantastic, and I have purchased back ups before they become unavailable!

AUDIO (base tuning): 2.5 AUDIO (with manual EQ tuning): 3.5 These little things impressed me when I first put them on (after figuring out a good position). Initially they were underwhelming, but once I found the best position on my ears the audio was crisp and clear. Bass highly lacked, but with these being open-ear ear buds that is to be expected. So, definitely not a bass-head type of ear bud. However, after spending some time to tweak the ear buds to a custom profile, I can say I am thoroughly impressed with the audio output capabilities of these ear buds. While the bass is no beats audio, I have reached a signature balance that brings a very cinematic audio feel to movies and other content. If I were to compare I would put the audio experience just below the Sony WF1000xm4 (which I have as well), minus the additional bass. Mids and highs are very close though. Software: 4 Does not give as many options to tweak the earbuds, but there really is not much to these earbuds aside from EQ and device connections. The EQ is very simplistic and easy tweak to the users sound profile preference. Comfort: 4.3 The earbuds do clamp a bit tight to my ears as it appears to do with a lot of people and when it comes to the main reason for me purchasing them (side sleeping buds) they are not a home run per se. They do a decent job but the ear of the side you end to sleep on does feel a little sore in the morning and in my case I took off that ear bud in my sleep at some point. Battery: 6 Holy cow! The battery of these tiny little thing are amazing. 10 hours easily before any charge is needed. Very impressive! None of my Sony's or Samsungs come close to this... AT ALL. One more thing to note would be that there is very audible audio heard from these things when you are next to someone. So, if you plan to get these things for a plane ride then I would recommend a pass and instead purchasing a closed-back ear bud... Or, if you turn the volume down A LOT then you might not annoy the person you are sitting next to. Bluetooth: 5 So far these things have put the bluetooth of my other wireless ear buds to shame. It has kept bluetooth connection where my other ear buds have failed. Final rating: 4.22 Great ear buds. Comfortable, with the ability to wear them all day AND has a battery capable to make them last all day. Takes some tweaking to bring out their potential but once you find that sweet spot these little buds sing.

These are amazing! This pair is beyond compare for comfort, performance and the value for the money. The case is sturdy, and so are the earbuds, I unfortunately have dropped them multiple times but have had no issues afterward. They connect well to multiple devices. The sound is clear, volume is good and they are super light. I forget that I have them on when I pause the music or audiobook. The battery life is super long usually one charge will last me from the time I wake up until I am going to bed, all day without issue.

I am seriously overjoyed at finding these! They are truly the only design on the market that keeps my ear free enough for my purposes. They are perfect for using in the office. I only wear the left one, since everyone else’s desks are to my right, and changed the audio settings in my phone to mono so I don’t miss any parts of the music. I work as inside sales support for a small electrical distribution firm so I have to be ready to answer the phone and be able to hear my coworkers in the small office too. I can pick up the phone and hold it to my left ear easily even with this on. I just pause the music first. I wanted something that wouldn’t need to be removed every time I had to hold the phone to my ear and this is it. I can also leave the music playing and hold the receiver to my right ear and hear the call perfectly. I used the app to change the touch commands. I have the “Hold for 2s” setting for the Play/Pause and it’s perfect. It’s easy to trigger by just holding the earbud with your thumb on the back. No fumbling around trying to find the sensor or needing to try multiple times to make it work. I did notice that it’s much more easily/accidentally triggered if you don’t use the plastic ear grips. I use the smallest one and it completely solved the problem of accidentally triggering the Play/Pause with my hood. I don’t necessarily need to use the ear grips for making the earbud fit, it fit fine without it, but adding the smallest one did not make them too tight at all. It’s super comfortable and I wear it for 8 hours a day, 5 days a week, and there is no soreness. I forget it’s on my ear. I’ve tested how well it will stay put by shaking my head and moving around in all sorts of dramatic way which I would never do in daily life and it doesn’t budge. The main reason I needed these is because I work in an office with 4 other people and they listen to the same god-awful music on a Bluetooth speaker every day. I was being driven insane by having to hear stuff like Limp Bizkit, Creed, Britney Spears, and 90s dance hits every day. I’m a music snob with some obscure, niche tastes and I didn’t want to make everyone else in the office unhappy by requesting to take over the speaker a few times a week. Even with just wearing the left earbud it drowns out their music and I can’t tell what they’re listening to. There is truly no sound bleed from these either. I don’t have it super loud, but loud enough to enjoy my music. I tested it and can’t even hear anything coming from the earbud if I have it in my hand or on my desk. I have long hair that hides my ears and I doubt anyone in the office even knows I have the earbud on. They definitely can’t tell I’m listening to my own music to drown out their nightmare office music. The sound quality is just fine for the average person. My husband is an audio engineer and I’m sure he would have some complaints about sound quality, but he lives and breathes audio so he’s very hard to please. For the purposes of passively listening to music while actively busy working, these are perfect. I first bought some of those bone conduction things with the strap around the back since the speakers sit on the temples and not on the ears at all, but I hated them and had to keep repositioning them because the strap would get bumped by my hair or hood. Plus it’s way more obvious that you have them on. The charge is impressive and I could probably go 3 or 4 days without charging, listening to music 8 hours a day. I love that the case holds a charge and I don’t even have to plug it in during the week and it recharges the earbud. I only plug it in on the weekend to charge it up for the week. You can find the battery levels for both earbuds and the case itself in the app. Lastly, I love how it looks. It really doesn’t matter compared to everything else, but I think it looks cool with the clearish outside and the components visible. It’s just a nerdy bonus for me. I truly LOVE this product!

I really wanted to love these! We have several other Soundcore Products and have found them to be reliable, with great sound and excellent battery life. I listen to audio books and podcasts for much of the day; sometimes as much as 10 hrs, and currently use Soundcore earbuds. I was attracted to the open-ear design and felt that style would be better (hearing other noises on walks and hikes, ear health, etc). I wear glasses and was excited about the clip style which don’t interfere. Positives: They paired seamlessly, the first time and every time. They sound good for my purposes and I could still hear noises around me. The microphone is good; friends said I was clear and there wasn’t a lot of background noise. They are pretty easy to put on, and they felt very secure. Negatives: The touch control is a nightmare. Every time someone was speaking to me I found myself tap, tap, tapping to attempt to pause the book, and eventually just got out my phone to pause. There is a small, raised circle where you are intended to tap, but it’s very slight, difficult to locate and even when I did, it didn’t consistently work. They are uncomfortable! At first they felt awesome and I was so pleased. But as the day wore on, I began to feel pain on the outside edge of the ear. When I removed the clip, I found that the edge of my ear was folded inward and having been turned in for about 4 hrs, it actually created a small “cut”. I next tried to wear them higher on my ear, at the smallest part of the ear, but then the speaker landed/pressed gently on interior cartilage and hurt after just an hour. I tried again, trying to ensure that my ear would not fold, but they just don’t allow room and the outer edge just crimps a little. I actually have small ears, with no piercings; maybe I’m just very sensitive. Even if they fit, the extremely poor touch control is a dealbreaker. I had high hopes, but these must go back and my listening hours returned to my old Soundcore Life P-2 in-ear buds.

EDIT: After I wrote this review, Anker reached out to me and offered to send me the updated version (Soundcore C40i) of these buds at no additional cost to me. I had not even heard of them being released as they apparently just came out. I tried to leave a review there but as I didn't technically purchase them, Amazon is not allowing me to, so I'm just going to leave a brief review here. I'm happy to report that the worst issue of the earlier version has been fully resolved so far as I can tell, as there is no discomfort whatsoever and they are much easier to put on and off. Unfortunately, one issue did remain and that is that my earlobe shape is apparently not well-suited for this style of earbud. They push the bud too far away from my ear canal and the sound comes through to me as super tinny with low volume. At first I thought that they just didn't put out enough sound, but once I pressed them closed to my ear canal, they actually sounded really good with decent volume and a full sound, so I'm sure it's just my lobe shape. I would be far less hesitant to recommend the C40i's to anyone interested as the pain issue is now gone, but I would still make sure you are aware that the sound may not be optimal for you if your ears are shaped a certain way. ------------------------------------------------------------- ------------------------------------------------------------- I read many reviews before I purchased this and many people raved about the comfort and fit these earphones provide. When I got my pair though, I was immediately struck by how difficult they were to put on and more importantly, how much they hurt! It wasn't super painful at first, but after wearing them for less than an hour, it became unbearable. I also found that just the act of putting them on and taking them off caused my left ear to swell a small amount which also made it harder to put back on. When comparing to other earphones with the same general form-factor, I think the obvious flaw is in the fact that the C30i are 100% rigid with absolutely zero flex. That makes comfort, easy of putting on and taking off, and even sound quality largely reliant on your specific ear shape and size. Clearly, these earphones work great for some, but I have never decided to return a product as fast as these. That out of the way, I will say that the sound was surprisingly high with little-to-no bass. I use Tozo Open Egos and while they won't blow you away with their sound quality, they were much better than the C30i. That may be due to a poor fit, but I have no way of determining that for certain. Lastly, I have questions about the placement of the touch controls. I was surprised to learn that they were on the back of the device, meaning that to use the controls, you essentially pinch your ear, with the thumb pressing against the back of your ear. The controls seemed to functino well, but I would imagine that depending on your body, the back of the earphones may make contact with your neck and cause accidental activations. Bottom line, while these may be servicable earphones for some, the fact that they are the cheapest earphones in this form factor by a mile means nothing if you can't comfortably use them. If they intrigue you and you are looking for the budget option, I can't say not to try these, but I would say that you should be prepared to return them if the odds are not in your favor.

I love open ear design headphones. I've been using variations of them for several years and I think they are just the best for what I use them for. I have a housecleaning business. So I need my hands free to answer phone calls, and I like to listen to podcasts and music while I'm working. My last foster puppy ate one of my over the ear buds by oledance (I had those for two years and loved them), soni was on the hunt for a new pair. I had seen the cuff style by Bose, but I was NOT spending that kind of money on earbuds lol. Anyways. Enter the Soundcore earcuff headset. I was so excited to find this style at such a great price, and all of my Bluetooth speakers are by souncore, so I was confident in the product right out the gate. Here's what I noticed. Out of the box, I was a little bummed about the case. It feels cheap, and it's super small (easy to lose haha). I've also noticed it doesn't hold as beefy as a charge as my last charging case by oledance. Which is fine really, it's not like I don't have chargers everywhere. So, a slight disappointment but not anything to get totally bothered over. The cuffs themselves are fantastic!! I'm a smaller person (seriously, I'm the size of a twelve yr old), so fit is generally an issue for me. These fit great, even without the included caps that help adjust for size. There are two sets of caps that are two sizes and they work really well to help the cuff he a bit tighter and hold it where you want it. So, while not necessary, I do use the caps as they help a touch. The cuffs are incredibly comfortable and don't fall out or off. I tested right away by shaking my head around, doing a couple floor rolls, and moving around like I'm at work (cleaning houses). Not only do they not move like at all, but they are insanely comfortable. I don't even know that I have them in most of the time, have panicked about them not being there when they are, and have even gotten confused about there the music is coming from when a button on my phone gets pressed accidentally. The accidental sounds coming from them really drive home how great they are, as it seriously sounds like it's coming from around you when you don't realize you accidentally turned Spotify on. Battery life is fantastic!! I can listen to whatever for HOURS and by the time I go to bed, I still have like 20% battery left at the least! Charging speed is also impressive. I was able to get my charger to finish the last half of my day in about 30 minutes. I still had several hours to go and they rocked the rest of the way through, and then some. The sound is great. I'm not a crazy audiophile, so I'm not super finicky about the sound. Bit I think these are pretty great for what they are! Having the app with the custom EQ setting is totally key. Plus, you can save several custom equipment settings for different types of entertainment. This is more than I need, but I think it's a great feature. I can't hear very well sometimes when I'm in the car. But I feel like with open ear headsets, that is to be expected. Phone call quality is great. Every person I've talked to since I've got these, I've made a pint to ask and everyone seems confused why I would ask and tell me I sound great haha. The touch controls are a little wonky, as others have said. There's definitely a curve to getting the hang of where the button is and what position your head and your hand need to be in to be efficient, and also how firmly you must tap to make it work. I do really enjoy that you can customize the controls through the app as well. You can also set each bud to respond differently to the prompt ling touch. For example, I can set my left bud to turn the volume up with two taps, and the right one to skip a song with two taps. And so on.... I'm conclusion! They aren't the very very very best, but for $70 I'm not mad. I'm actually impressed. And I'm super duper happy I bought these! I even went ahead and purchased the over the ear style that souncore offers (they are like twice the price) (I started getting , but they don't fit my ears well. And they literally sound exactly the same as what I have. So back they go! In conclusion. These are great. I think they are well worth the money. Humans with larger ears (as brought up in other reviews) probably won't like these as far as comfort is concerned, but not everything fits anyone. Definitely recommend!!!
