Anker Soundcore Liberty 4. I purchased these in April 2025, but I'm selling them because I bought new earphones. There are some minor scratches inside the case, but there are almost no noticeable scratches, and I think the condition is relatively good. *Please check the photos for the condition. There were no unusual noises, and they were working without any problems. The battery life is also fine. *The main unit has been initialized. The main unit and accessories are as shown in the photos. Please understand that these are used items before purchasing. Please refrain from purchasing if you are sensitive to used items. Other features: Noise canceling
