Wireless earbuds equipped with active noise canceling function. Purchased on Amazon in August 2022. Usage has decreased in the last two years, so I'm selling them. The battery has worn down accordingly, but the app shows 100% charge and they work fine for several hours. The case has scratches from being carried around, but the earbuds themselves are relatively clean. - Brand: earfun - Model Name: EarFun Air S - Type: Wireless Earbuds - Included Items: Instruction manual Thank you for looking.
