Black Bose QuietComfort II earbuds with S/M/L size ear tips with fins. I was using size L. I only tried size M on once. The earphones worked perfectly fine. I'm not sure of the exact time, but I was satisfied with the battery life. I lost the charging case, so I'm selling what's pictured at a bargain price. - Included: USB charging cable - Ear tip sizes: S, M, L - Earphone color: Black - Design: Canal type Thank you for looking.
