Anker Soundcore Liberty 4 - Color: Black - Type: Wireless Earphones - Design: Canal type Purchased on Amazon in mid-July of this year. Used a few times and decided to sell them because they didn't fit. There is a small scratch of about 0.5mm on the left earphone, but it does not affect use. There are no problems with sound quality or functionality, and all accessories are included. Operation has been confirmed. Thank you for looking.
