New, unused. I purchased these because the 2nd generation was released, but my 1st generation ones are still usable, so I don't plan to use these. In the unlikely event of an initial defect, please contact the manufacturer for a new replacement. Please check the serial number. I will ship immediately, so thank you. - Brand: BOSE - Model Name: QuietComfort Ultra Earbuds - Generation: 2nd GEN - Features: Noise Cancelling
