Purchased in 2020. Excellent condition. Cleaned with alcohol. Work as they should. These Bluetooth headphones come with 6 pair of new ear tips in Small, Medium and Large to guarantee a precise fit. Ear tips are still sealed in the plastic bags. I used these for skiing and road biking. 10 hour battery life, superior noise cancelling that you would expect from Bose. Includes original case and UCB-C charging cable.
