Purchased in August 2025. I've been a BOSE fan for 30 years. I'm selling these because I've been using the 1st generation, but as I've gotten older, I've found it harder to hear high frequencies, and I no longer feel the enjoyment of using high-spec earphones. Experience the wonderful deep bass and sound quality of BOSE. Silicone case included. Very convenient for carrying around. Since it's new and unopened, I haven't checked the operation. In the unlikely event of an initial defect, it will be replaced with a new one by the manufacturer, so please purchase with confidence. You can confirm this with the serial number. I will carefully package and ship it safely and securely. Thank you. - Bose's 2nd generation QuietComfort Ultra Earbuds with noise-canceling function.
