Thank you for viewing. This is the soundcore Liberty 4. ・Condition of the product I have used it for about two years since I purchased it. It works without any problems. I used the S size ear tips. I have wiped the used parts with alcohol as much as possible. I hope to sell it to someone who understands that it is a used item and doesn't mind minor scratches or scuffs. Please note that we do not accept price reductions or holds, as they may cause trouble. No returns or refunds, please. Thank you. - Model name: Liberty 4 - Brand: soundcore by Anker - Waterproof rating: IPX4 - Battery life: 28 hours - Accessories: Ear tips (multiple sizes) - Charging case: Included Box, replacement ear tips (unused), and other accessories included.
