I was looking for this item. Everyone else said two weeks out and 6 dollars shipping. Free shipping and received in 3 days. Thank you guys.

I am glad I got this because I have really small ears. I ended up using extra small (this came with the alternate kit) for one ear and using small which came with Bose earbuds for the other ear

So glad I tried these. What shipped with the buds were to small. Was so surprised by the difference in blocking sound even before I connected the buds to my phone. Very secure fit and now I can pass the fit test.

I needed the smaller pieces to have them fit properly and now they are comfortable

This enabled me to get a good fit.

I recently received a new of Bose Quiet Comfort II earbuds. I installed the size small tips and bands but they still were too snug in my ears. I was a bit skeptical but decided to give it a try. Game changer! This morning I installed the size extra small from this kit and they are exactly what I needed! I still have a great fit, just more comfortable for my ear size. I just wish for the price of the earbuds that all sizes were included.

The part that you attach to the rim of the earbud broke for me when expanding it to cover the hole properly. The XS ear cover itself was as expected and fits better for me than Small.

Although the ear buds come with three sizes it doesn't come with their extra large or the smallest size the make. If you need either of those sizes you'll need to purchase these in addition to what comes with their earbuds. Bose didn't have them in stock so I went ahead and purchased them here instead. Just the fit I needed
