I used these for about six months in total. There's been no degradation of the noise cancellation or connection issues at all. I listened for 2 hours straight and the connection never dropped once. Everything in the photos is included. I'll also include the case. All sizes of ear tips and ear fins are included. All sizes except L are unused. I'm selling these because I'm buying headphones. Bose wireless earbuds, black. They provide a high-quality and comfortable listening experience. - Color: Black - Type: Wireless Earbuds - Brand: Bose - Model: Bose Earbuds Thank you for looking.
