I couldnt figure out how the adjustable strap would function on the average foot: one hole is super-tight and one hole is super-loose. I was battling really dry skin from my retin a- and the face wash and night cream turned it around within 2 nights. I recently bought Etymotics excellent ER2XR and have been really enjoying them. A great product for my 2017 highlander. This is a great pair to wear indoors, I will tell my friends about them back home. I tried to plug in something and the force required made me afraid I would break something. I have small ankles so they work for me in the very last hole of the ankle wrap. Product was not very sturdy. * G-clicky is a thing, Logitech got it right A+. I do not recommend this if you are looking for a sweat enhancer.
