Thank you for viewing. The Soundcore Liberty 4 NC are wireless earbuds equipped with noise-canceling functionality. The left earbud was submerged in water during use. Although both earbuds are present, only the right one works. They were used for about a year. Please consult if you wish to purchase only the earbuds or only the charging case. - Model Name: Liberty 4 NC - Color: Dark Blue - Brand: Soundcore
