This is a limited edition Campfire Audio Supermoon, with only 25 units produced. I am a long-time user of the custom version of this product, and I purchased this limited edition for my collection. However, I need a significant amount of funds in the near future, so I am putting it up for sale. The earphones themselves were kept for collection purposes, so I only checked the differences from the custom version for a few minutes after purchase, and they are in like-new condition. Therefore, there are no scratches or stains. Only the included 4.4mm cable was used with other earphones, so there are some minor scratches on the plug. Other accessories are unused and complete. Please consider purchasing.
