I have the open run 2. . . awesome! I like how they feel. I am glad I bought the smaller headphones. I wear high collars when it's cold. I don't have much of a problem with the loop around my neck hitting or catching on things. My old headphones were broken from getting caught on things in my garage. The amount of time it takes to bring to a full charge and how long the charge lasts is amazing. Super happy about that! I like the sound. It's lacking a little in bass. I was not offered the drawstring bag. I could have used that. I ride motorcycles with a backpack. The drawstring bag would be way more useful due to the compact ability.
Cannot hear unless placed over the ear canal. And due to design they don't fit properly having to use them that way. Definitely no Bone Conducting happening.
