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 main 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 have purchased new earbuds. In preparation for the sale, I have performed a simple disinfection and cleaning. The sound quality is excellent, and the charging case has a large battery capacity, so the battery lasts for a month without charging the case. These are wonderful earbuds. Although there is no active noise canceling function, the physical sound isolation performance is quite high, so it's not something you'll likely notice. 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.
