The BOSE QuietComfort Ultra are wireless earbuds with noise-canceling features, and they come in stylish black. They include a blue silicone case worth approximately 2,000 yen, making them a great deal. Retail price: 39,600 yen There are scratches on the charging case, but there are no issues with its use. The earbuds have never been dropped. As expected from BOSE products, they have powerful bass. They are highly rated as earbuds, and I also use mini headphones and speakers from the same brand. I love that I can customize them through the dedicated app. The noise-canceling feature is excellent, and you'll understand how amazing it is when you put them on. I am selling them because I am using other Bluetooth earbuds. These are high-end and popular Bluetooth earbuds. They are also listed on auction sites. - Brand: BOSE - Model Name: QuietComfort Ultra - Features: Noise-canceling - Color: Black - Silicone case color: Blue Please note that these are used items and are sold as-is, with no returns or exchanges.
