We bought two. As for durability, thats something well have to wait. Y es que en la calidad está en los detalles, los de Sennheiser han pensado en todo! After a few quick diagnostic questions, she figured out the problem and arranged to overnight the correct straps. Very cozy and warm - Just the right height - not too tall, not too short. The waterproofing and shank are big pluses for me. Cute little pom pom on top. All in all they are a great gaming headset for the money. With that said, at the optimal angle, my heavy bike is fairly stable.
