Whether you are looking for a brand-new or second-hand koss headphones, eBay offers one of the largest selections available online.

The cheapest option currently starts at $4.8, while premium listings can reach $324.99 — giving you a wide budget spread to work with. The average price of $37.57 can serve as a useful benchmark: listings below this tend to be used or auction-style, while those above often include extra accessories, warranties, or are sold by professional sellers with high feedback scores. Always check the seller's feedback rating and return policy before committing to a purchase. If you need the item quickly, filter by "Buy It Now" to avoid the uncertainty of auctions. For used items, look closely at the condition description and photos — terms like "good", "very good" and "like new" can mean very different things depending on the seller.
