added rubber cushions hold the bud in place even while moving.- easy to connect for first time, long battery life.- cord feels firm and im less afraid of the wire pulling apart during HIIT like my last pair did (different brand).- control box has a light weight to it and doesnt feel like theres much heft to hit against my neck, or pull the bud from my ear.- magnet on back of the buds is convenient for wrapping around your neck when buds are not in ear, and make it easy to keep track of them without them falling off
