Too bad as the products are great, but the company is misleading. Possibly just a defective pair? Heard great things about them but for the price the mic working is a must! These headphones resolve string music admirably, and find the other genres just as easy. This thing is an absolute dream, Im actually using it to type this review. I purchased Corsair cherry mx speed keyboard on 5th Oct. It checked all of my requirement boxes; not in ear, lightweight, and waterproof. this one is the more expensive if the two . I finally found out that the smallest size in this pack fits my ear well enough while no other brand can offer a size that does. Definitely order to your usual size Im trying to figure out how to add holes.
