Bone Conduction Headphones Premium Open-Ear Wireless Bluetooth Sport Headphones with Microphones, Sweatproof Waterproof Wireless Earphones for Run...

These are pretty good. The sound is actually quite clear. If you're in a noisy environment it may be hard to discern speech, like an audiobook or podcast since no outside sound is blocked. In those cases I listen to music. In less noisy/quiet environments no issues. As some others have said, they're not really TRUE bone conduction. I haven't put earplugs in, but if I plug my ears while wearing them the audio quality diminishes. You can feel them vibrating the side of your face, but its easy for me to ignore. They do some bone conduction. Maybe like half bone, have open ear. Other people can hear them more than earbuds. Being able to hear what is going on around is nice when you need it. Depending how loud the volume is set, you may not be able to understand someone talking to you, but at least you will know they are talking to you and you can pause. They're reasonably comfortable and battery life is long. I like to wear them while doing (not motorized) yard work. They won't fall off, good sound. Can hear around me. I've been able to wear them for many hours of continuous use without needed a recharge not my ears becoming too sore. The fit isn't perfect, but it's alright. The only thing I don't really like is there is only 1 physical button. It is pretty basic but you learn to live with it and go back to your phone for more "complex" functions. I really only use it to power on/off, play/pause and hang up phone calls. I think you can also skip to next song, but I just use the phone for that and volume. For the PRICE it's a good deal.

Sound quality is good, the fit is nice and sturdy on head for biking and running, pretty comfortable.
