Hello! Thanks for reading and for the reply!
It’s interesting that you’ve read that the build quality has gone down on current pairs. They’ve made some changes to things like cord thickness and the included case recently, so hopefully the main build isn’t on the way down as well! I haven’t purchased any of Sony’s classic headphones for about a year and a half now, so someday I might have to revisit these to see whether the current models are up to the old standard.
