SO GOOD (even for bass music!)
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.

Read this.
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!

Great fit and do what they meant to really well If you want deep immersive sound these are not for you. But if you want to hear the kids while you listening to your music these are a great option

I have small ear canals so other types of ear buds start to hurt or fall out of my ears. The Soundcore ones suit me so well. It took me a little while to get used to putting them on but now I'm used to it, it's easy. Sound is good and I'm still aware of my surroundings when wearing them.

These earbuds are so light and easy to wear. I hate the in ear earbuds but like having something light so these meet all my needs. Battery life is decent, sound is clear and Bluetooth connection is rock solid. So good I bought another pair as a present and it was very appreciated.

They're pretty comfortable if you can get them into the correct position in your ears. Just be aware that if you have multiple ear piercings, these earbuds will not work well for you, as they act like cuffs from the front to the back of the ear. The sound is nice, the music and audiobooks come through clearly. It's nice that you can crank the volume and still hear environmental noises, making it a nice option for walking around outside and being aware of your surroundings.
