Selling used excellent condition Sennheiser HD 660S2 headphones. Owned since December 2023. Used with a mix of other daily headphones, decided that I need to reduce my collection. Marking them in "Good" condition simply due to pad wear. Otherwise the plastic, metal, etc is excellent condition. See photos.

Comes in original box with both 6.35mm SE and 4.4mm balanced cables and paperwork. I have 100% rating on eBay and can provide link to my profile if interested. Cost includes PayPal G&S fees and USPS Priority shipping. Comes from smoke free home. I ship super fast, usually same day or next day after payment received. I have an account with Stamps(dot)com and can provide tracking information after payment received.
