So mine just came from the post and I have been using it for the past few hours. I am quite surprised with the sound quality of these headphones. They are on par with my Audio Technica ATH-M30x. One gripe I have with these headphones is the jack. Like the ATH-M30x, I can't plug it on my Samsung Galaxy S9+ with the protective standing case on.
Despite it, I can't recommend this fine headphones enough.
