Thank you for viewing my item. #knakajima's Hobby This is a BOSE noise-canceling earphone, QuietComfort Earbuds II. I purchased this about a year ago. The left earbud sometimes has trouble with high frequencies, so I am selling it as a junk item. The right earbud and charging in the case work without any problems. Please consider this item with the above in mind, as it has been stored at home. Bose Earphones Bose Model Name...QuietComfort Earbuds II Other Features...Noise Canceling
