I'm considering a small discount, so please comment first. The item was purchased used from Amazon, and is an official product. As a purchase bonus, I'll include a 4.4mm MMCX cable as a free gift. This is a custom-made cable that I purchased for about 9500 yen. There are no sound issues. I haven't used it much since I bought it, so it's in good condition. Please understand that this is a used item. No returns accepted. The IE 300 offers a high-quality music experience. - Brand: Sennheiser - Model Name: IE 300 - Included Accessories: Case, Instruction Manual - Design Features: Ergonomic fit - Logo: Sennheiser logo is visible Thank you for viewing.
