These are Sennheiser IE60 wired earphones. The flat frequency response across all ranges and the superb sound quality are truly worthy of Sennheiser, providing satisfaction across all genres. Being wired, there's no delay or sound dropouts, and you can enjoy high-quality music without worrying about battery life. What I'm offering is the main unit only (tested and working). They are originally designed to be worn over the ear, but they can be used normally without doing so. I don't think there are any noticeable scratches or stains, but please understand that these are used items.
