No hace ruido y en general, funcionó perfectamente. Although these are made in Mexico just like Fruit of the Loom, the quality is better and the material is thicker. These have now shrunk to a size 9. (I use it little less, max when i am traveling)**It is a good sounding pair. Male and female vocals are well presented. The head phones dont fold up so it is to be expected. When I unpacked the product, I noticed the one of the end stopper is broken. I don’t know why there aren’t more manufacturers making this type of show anymore. As a huge fan of this film, I was extremely happy for the 4K version to be released. I bought these and seems to be great so far
