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.

So these are similar to some other earbuds that I have do not go directly in your ear canal. What I mean by that is for me and because of the shape of my ears I can place them in two different positions. Both work with one being a little more comfortable than the other for long term use. One position puts the speaker end further into my ear, although still not into the ear canal, and there by closer to my ear drum. Not sure if it is the position or the firmware update, that these had available to install when I got them, or both; but I have no problem with the amount of bass they put out. In fact in relation to bass I can feel them vibrate against my skin playing a song that is bass heavy without the volume being all the way up. Unfortunately the only way to know if these will work for you is to buy them and use them. Based on the reviews these are not one size fits all which I think it is more accurate to say these are not one "shape" fits all. Other reviewers have said they aren't for people with big ears and I don't consider myself to have small ears. Based on a face attractive assessment I did years ago it said my face is attractive; but my ears are too big. An assessment that I agree with at least in relation to the size of my ears lol. But it is not about the height of your ears; but the width. In other words it is more about the distance of the side edge of your outer ear and distance to your ear canal. The wider the distance of this area of your ear the further away the speaker end of the ear buds will be from your ear canal. This will cause less volume as well as less bass. Luckily for me my ears may be tall; but they are not very wide around the ear canal. I just got these and I am listening to music while writing this review. So far I think they are very comfortable, and have had no discomfort, straight out of the box without the use of the additional attachments. Honestly the bass is just fine which is probably due to the fact that the speaker is fairly close to my ear canal; because of the shape of my ears. I listen to a lot of EDM and the amount of bass you get is also probably dependent on what app you are using to play music and if you play around with the EQ that comes with the earbuds which I did not do. If you like open ear earbuds and or are looking for something that may be more comfortable then the in the ear type I would gives these a try. The only way to know, on these type of ear buds, if they will work for you is to actually try them; because no reviewer is going to take into account the shape of their ears in relation to yours. I would buy these again if something were to happen to them.Update: Still find these to be the most comfortable earbuds I have; but have gone with using the medium (which is the first size) cover size adjustment. The largest cover for me causes discomfort when wearing them for extended period of time (kind of a pinching feeling). Without any size cover I found that if I bend over like to pick something up the earbud will press against my head and cause the button to activate (I use long press to change songs). With the cover added I have found this accidental pressing does not happen as often or at all.
