I purchased this on Mercari and it works fine, with no issues. However, I am selling it because I am sensitive to the smell of cigarettes. If you don't mind the smell, please consider purchasing. As this is a used item, returns are not accepted. Please understand this before purchasing. - Brand: SONY - Model Name: MDR-M1ST - Accessories: Instruction manual, cable - Type: Studio monitor headphones - Design: Over-ear
