This is a Sennheiser IE 200. I bought it for working at home, but it mostly just sat there, so I'm selling it to declutter. After the initial burn-in period, it was mostly just sitting, so I haven't used it much. The included cable and ear tips are unused, as I used aftermarket ones from the start. I'll also include a 3.5mm replacement cable, which I bought at the same time for ease of use. The main unit isn't unused, so please check the images carefully before purchasing.
