Ope-air headphones are particularly popular among runners who prefer to stay aware of their surroundings. Very rightly so; when running on the road, you're part of the traffic, including cars, bicycles, etc. Open-ear headphones provide much-needed spatial awareness while allowing you to listen to music or podcasts on the go.
Shokz is probably the biggest – or, at least, the most well-known – player in the open-ear headphones business, but many others produce quality audio equipment with spatial awareness capabilities. Cleer is one of these brands, and with their latest fitness-oriented offering, the ARC II Sport, they hit the nail on the head.
