Anker's Soundcore Liberty 4. There are some minor scratches, but it should work without any problems. I will include the ear tips and instruction manual, but not the box. If you would like the box, please contact me, and I will include it for an additional 300 yen. I'm not a professional, but I have cleaned them. The ear tips are unused. - Brand: soundcore - Model Name: Liberty 4 - Features: Ultra Noise Cancelling - Audio Quality: High-Resolution Audio - Included Items: Instruction manual, ear tips #Anker #WirelessEarphones
