Charter Oak SP-1

Charter Oak SP-1 closed back headphones in excellent condition and clean. I’m not the original owner of these, and I used them very sparingly. It comes with a wooden storage box that is actually quite nice… the box has a few marks on it from the prior owner or I would have considered the set mint. Being closed back they have nice isolation if you’re recording something acoustic and want to avoid bleed. Great sounding headphones from a smaller company who make excellent mics as well. These retailed new for $375
