The BOSE QuietComfort Ultra are wireless earbuds with noise-canceling features, in stylish black. They come with a blue silicone case, worth approximately 2,000 yen, making it a great deal. Purchased in March from the BOSE store. Used for about six months. Retail price: 39,600 yen There are scratches on the charging case, but there are no issues with its functionality. The earbuds have never been dropped. As expected from BOSE, the bass has a powerful impact. I highly rate these earbuds, and I also use mini headphones and speakers from the brand. I love that I can customize them to my liking through the dedicated app. The noise-canceling feature is excellent, and you'll immediately notice 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 this is a used item, and no returns or refunds are accepted.
