This is my first “air conduction” headphones purchase, and I’m honestly impressed. I’m used to either traditional earbuds or noise-canceling over-ear phones, so this was a new experience for me. Here are my impressions:Very comfortable. Since this sits gently over your ear and not inside it or covering it completely, this is something you can barely tell you’re wearing if you’re not paying attention to it. It’s lightweight and no matter how much I shook my head around, it did not move one bit. This would be *perfect* for runners or people doing a lot of physical activity while listening to music.Sound quality is very good. You get a full range of low and high tones with great clarity for an inexpensive audio accessory. I listened to several types of music and spoken word podcasts and was satisfied with the quality on everything.Since this is basically a speaker hovering over the opening of your ear, this is not the sort of thing you’d wear in a setting where privacy or staying quiet is a concern. Others around you can hear it clearly if the room is very quiet. But by the same token, if someone wants to have a conversation with you while you’re wearing this, you don’t need to take it off or pause your music or even turn it town if you want to hear them, in most cases. I see this as helpful around the house or out on a walk or run, just not in a quiet classroom or a library. You can remain situationally aware of your surroundings while going about your business, and carry on a normal conversation with someone else without shouting or needing them to shout for you to hear them clearly, all while keeping your music going. Amazon is asking me to rate its noice cancellation quality, so I’d give it two stars on that “metric” in the text here, but it’s not meant to be a noise-cancelling headset, so I’m leaving that one blank on the review stars.I’ll say battery life is good, although I have not used it enough to drain it completely yet. But I got a couple hours of use out of it straight out of the box, and it was 80% full according to my phone when I first powered it up. A couple hours later, it was still reading 70% on my battery widget.When I first opened it up, I was a little confused that there were two charging cables. My knee-jerk reaction to that was “wow that’s stupid, you have to charge the two sides separately???” But that’s incorrect. They just give you an extra charging cable (and the user guide mentions this), which is a really nice move on their part because this requires an unconventional charging cable. That’s probably the only “ding” I can think of on the design here - would prefer to make it work with standard USB C or wireless charging, but if you’re going to force a proprietary charging format, providing two cables out of the gate is a very nice move so you can have a backup or keep one in the two most frequent places you’ll use it.Overall - I’d definitely recommend this for anyone who has comfort issues with earbuds or over-ear headphones. Or for people who have a hard time with earbuds fitting them properly - whether they fall out a lot or are too big, etc - because this hangs perfectly over the top of your ear. It’s not super adjustable, so this is a “one size fits most” sort of situation, but it did fit me perfectly without issue. The user manual says to “adjust” the fit when you put it on, but I honestly couldn’t find any way to move or rotate the speaker pods in any permanent way. There is some flex in it, but it just sort of bounces back to normal if you try to move it. So although you could get a more “immersive” experience if you can situate it in a way that it fully fills your outer ear area, I don’t think it’s all that adjustable. wasn’t an issue for me though.In my case, I tried it out and then passed it along to our 15-year old daughter because she has a hard time finding earbuds she likes (and she’s prone to losing them). Since these are attached to one another by the band that wraps around the back of your head, I'm confident we won’t have that issue with this one. Everybody wins!
