Campfire Audio ANDROMEDA 2020. Purchased used in June 2025. After purchase, it was only used indoors, never taken outside. Approximately 100 hours of burn-in time was applied. The sound quality changed remarkably. I am selling these because I purchased new earphones. Although they are in good condition, there are some minor scratches on the body. Please refrain from purchasing if you are looking for a perfect item, as it has been handled by another person. I do not smoke, and I do not have any pets. No returns, refunds, or exchanges (3N). Thank you for looking.
