Thank you for viewing! This is the Anker AeroFit (pink). I bought these, but they didn't fit my ears, so I'm selling them. I've only used them about 1-2 times to try them out, so they are practically unused! I purchased them in July 2025. I will disinfect the ear parts with alcohol before shipping. The box and all accessories are included, but if you don't need the box, I will discount the price by ¥50. (Retail price: ¥12,990) They are almost new, but they have been handled by a person once, so I appreciate your understanding. Please feel free to ask any questions in the comments section!
