Shokz OpenRun Pro 2: One minute review
The Shokz OpenFit Air are probably the best running headphones for people in the 5k to half-marathon distance bracket who want to be able to hear their surroundings when they train and race. Offering a very reasonable 6 hours on a full charge, the battery life will get most people through a full marathon, too, although more expensive Shokz options give double the playtime.
