Wired Bose QuietComfort 20i earbuds with active noise cancellation. Purchased at Bic Camera several years ago and used regularly, with no issues. The outer rubber of the noise-canceling box on the earbuds is peeling. The connecting cable at the bottom is protected with tape. Sometimes there is an electrical hum when noise cancellation is turned on. - Model Name: QuietComfort 20i - Accessories: None - Brand: Bose - Type: Wired Earbuds - Features: Active Noise Cancellation Thank you for looking.
