Shokz Knochenschall Kopfhoerer OpenRun Pro 2 Silver (S820SI)

Battery lasted over eight hours and was still going strong. Very light and comfortable with nice sound quality.

Awesome headset. Tip for when using the app: set your country to US. This seems to be the only way to get the "Classic" mode (100% bone conduction) to be available as an option. Annoying that it's closed for other countries.

Excellent for riding. When riding fast the wind noise could be very noticeable but that is something no headphone could resolve. Other than that you can talk or listen to something while being fully aware of your surrounding. The physical volume buttons work perfectly and the one push button to accept or initiate calls (I use Siri for this) is fantastic. I have mine and bought one for my son for his rides as well and he definitely loved it.

Drastic improvement from the first-gen, which to me had pretty terrible audio, although a cool concept. The new traditional speakers in addition to the bone conducting speakers make these sound infinitely better. Perfect for running, cycling and other activities where you need to have situational awareness of your surroundings.

Although it is a good pair of earphones , sound is weak in even slightly loud environments. You will wish it had slightly more volume. Battery power is okayish.
