Yes, you know them well. Whenever there’s a scene of a recording studio on TV or in a film, the artist will almost always be wearing a pair of these, LOL. I have two of these for sale. Both are 400 Ohm versions.
I also have three Beyerdynamic DT-102 single-ear headphones for sale at the moment.

These units are just brilliant and I have used them in so many situations. They’re great!
