I work in a busy automotive shop and I'm always in motion and on the phone. I need to be able to hear my surroundings, take phone calls, and sometimes need to wear earplugs. This headset is comfortable enough to wear all day long, keeps my ears free for situational awareness, and allows me to wear earplugs when needed for protection, and even then I can still take a phone call.
I have been using the OpenRun Pro 2 for about a month. They have good sound quality and I like not having tips in my ear canal. I could probably gone with the small instead of standard size. The technology to use bone conduction is awesome though.
They work pretty good. In loud noise I have a hard time hearing them even with the volume turned all the way up. When not in a loud noise area they work good.
