Apparently this is fashion-ear headphones, which lodge deep in the ear, that I bought by mistake before, and I do not like because it completely mutes the outside and it bothers me. It's like to have earplugs in the ears. In addition to this, the previous model I bought another brand, had broken very quickly. These are much more classic, and I do not think they meet the definition of in-ear because it can not fit in the ear. They work very well, and I think they are very satisfactory, with a rich sound for headphones so small. I work in the field of audio, and I'm used to listen with professional headsets, and I think these headphones for the price is really good.
