My Beyerdynamic DT 1770 Pros studio headphones were a recent purchase from a few months ago. They are a great set of headphones and my personal favorites. They were diligently kept in their case when not in use, which was almost always. I haven’t been able to do as much music production as I planned when I originally bought them, so let’s find them a better home ;) They are a recent purchase with very little use and there are zero flaws so they are somewhere between “like new” and “good.”
