Well smothered noises, but strong clip the ears (it makes long-term harm); especially not solid! The clamp head (plastic) has completely broken in two after just 3 months of use !! Yet I do not do an action profession, I have a desk job in a "open space" and I just put qq hours a day to better focus on my records ... So I have to buy a 2 times more expensive ... A tip: buy the most expensive head directly with a greenhouse that is not plastic ...
