Sennheiser HD 800 S, serial number 00646. They come complete with presentation box and the following contents: Cloth carry bag XLR balanced cable Original 6.3mm cable User manual Microfibre cleaning cloth Flash drive Original purchase invoice 825 GBP ONO. I will sell to anywhere, but shipping may be prohibitive for buyers outside the UK, so would prefer a UK buyer, ideally someone who can collect in person from London. Please send PM if interested. The headphones are in very good condition. The only slight defect are some small scratches to the silver bezel near the right-side connector (see photos for better resolution). The box and contents are all in excellent condition. The cardboard wrapper is a bit of a loose fit around the box, but that is how it came.
