SENNHEISER HD660S2 Open-Back Headphones - Body Only The HD660S2, highly regarded even for professional recording purposes. I mainly used these for recording and mix confirmation. - Operation confirmed - No issues with sound - No box or accessories (body only) - Paint peeling on the mesh part of the outer ear cup (see photo) - The cable and ear pads have been used a few times, so they may show some wear compared to new ones. With high resolution and a very well-balanced sound from low to high frequencies, these are recommended for both production and listening. Please understand the condition as this is a used item before purchasing.
