The mic boom is very flexible but holds its position. Other than that, love the look and sturdiest of the product. That being said, since I still need to wear the foam ear plugs underneath them, I?m going to knock one star off. very well made, and the size 9 fits me as I expected it to. Im out on Sketcher products for life. Literally my home had to be silent. Much better than the ones supplied from original manufacturer. Bought my son size 8. Other than that they sound great and are plenty loud for my shop which can get very loud! This has been a great addition to our home gym.
