Experience premium sound with Bose QuietComfort Ultra earbuds. Advanced noise cancelling technology. Stylish dark blue finish. Bose QuietComfort Ultra Earbuds that are unopened and brand new! They are not used, refurbished, or opened in any way! They are the dark “Lunar Blue.” I have a pair myself and have not had any trouble with them at all! There is an array of sizes for the earbuds inside. Their replacement policy is superb and quick; they have a beautiful sound profile and great apps; and they are truly worth the original price of $350. P.S. You can buy cute cases and accessories on AliExpress (a few on Amazon as well).
