This is the LYPERTEK wireless earbuds, the PUREPLAY C3. As shown in the 9th photo, I had the earbuds inspected in July because one ear stopped working. Both the left and right earbuds, as well as the case, were replaced with new ones. I haven't used them at all since the replacement and have been storing them. I am selling them now because I bought new earbuds. I have disinfected and cleaned them in a simple manner before listing. The sound quality is excellent, and the case has a large battery capacity, so the battery lasts for a month without charging the case. These are great earbuds. Although they don't have active noise canceling, they have a high level of physical sound isolation, so it's not a concern. Please refer to the official website for detailed information. https://knicom.co.jp/product/pureplay-c3/ I used my own charging cable and ear tips, so they are unused. - Brand: LYPERTEK - Model Name: PUREPLAY C3 - Accessories: Quick Start Guide - Charging Case: Yes - Earphone Color: Black Thank you for looking.
