As a tech guy, I have bought a lot of gadgets over the years and this is one of the best. It uses bone conduction sound leaving your ears open to better hear the environment around you. The speakers press against the skin just in front of your ears. At 20Hz-20KHz you get the full audio range of the human ear. They are lightweight and can be worn all day. The noise-canceling boom mike is excellent. There can be wind noise in some conditions when riding a bike but otherwise, the recording quality is very good. On my Mac, I use it to record audio, otherwise, it is paired with my Android phone playing music or audiobooks. It is a perfect companion for long walks with audiobooks or doing chores around the house.
As for negatives, at $160 it is expensive. Also, the user manual that ships with it is printed with a micro-font that was difficult to read. I copied the information to make the table below. I bought it directly from Aftershokz, link.
