Thank you for viewing. I used these for about a year and have been storing them since I bought different earphones. As shown in the photos, I have confirmed that they power on, charge, connect via Bluetooth, and produce sound. The case has noticeable scratches, but the earphones themselves only have minor scratches, with no significant damage. Please refrain from purchasing if you are sensitive to used items or seek a perfect product, to avoid any potential issues. For hygiene reasons, I will remove the ear tips shown in the photos before selling. Please prepare your own.
