It’s the best stuff on the market. The actual bars feels sturdy. had to change pads for leather ones to achieve more secure sound and bass. Then when you scroll, stop scrolling and remove your finger from the scroll wheel, its likely to move a little bit. I have used this one time (3 sets of 5 reps) and it is extremely uncomfortable to use. I will wear them at the pool, but primarily in my home in the summer when I its too hot to wear other shoes. I do Russian twists with them, and then lie on my back with the ball at my chest, raise it up straight, then back over my head until it touches the floor. The headset was comfortable even on long calls but the boom mic is rigid and can not be adjusted, it was practically in my mouth which caused a bit of distortion. Which actually looks better. I get the package, I open it.
