I'm selling a pair of ~2007 Beyerdynamic DT48 headphones. Brand New and boxed.
These have something of a cult following - having a perfectly flat response ideal for monitoring/recording human voices.
"Made to a specification for film producers and sound engineers these headphones have a flat frequency response with excellent isolation giving an accurate sound reproduction with minimal distraction from the outside world. With an ergonomic design these headphones are ideal for long days out recording and long nights in the studio too."
