What a shock when I put them on! Here, Colgate Hydris proves to be a superior option. It works perfectly so far with all headphones in their own spaces. Packaging was perfect, and the IGI certification card and appraisal was enclosed, as promised. Love the product and the customer support. You will more than likely have to remove one to hear others around you, when I used both and simply paused I could not hear the people around me still. Il est arrivé dès le lendemain et en parfait état (comme neuf). The sun easily kills the paint on these. Also it looks like a plastic material in the photos but dont be fooled the base of it is like marshmallows! Maybe its something ill get used to? If it helps with back pain and posture, im sure ill get used to it!
