This is my second pair of bone conducting headphones from the same company. The first set were good but i didn't look after them so well and they came apart. That was about 5 years ago. These new ones have a nice case to keep them safe when not in use, and they work really well. I can't say whether they are better than others but the sound seems fine to me. I had been using in ear buds whilst running and though they rarely came out I often expected them to. And if they did on occasion fall out they were hard to find. So the fit of the aftershokz is fine and feels secure.
