This is a super limited wireless headphone, a giveaway for only 15 lucky winners in a campaign for Volume 18 of "Call of the Night." It's a non-sale, rare item, a collector's item that rarely appears on the market. While it has been used sparingly, it is a pre-owned item that has been in someone's possession, so please check the photos carefully for the condition. I have briefly confirmed its operation, but this is being sold as a collector's item, so please purchase it for display purposes only. The included cables are missing. Please be aware of this.
