[3 Pairs] Ear Tips Covers for Bose QuietComfort Earbuds II&Bose QuietComfort Ultra Earbuds, WOFRO Anti Slip Silicone Sport Wingtip Anti Scratches Eartip Accessories (S/M/L) -White

These are so much more snug fitting than the ones that came with my Bose earbuds. Awesome sounding earbuds but loose fitting ear covers. These took care of that. Some reviews said that it affected the charging. Not in my case, works great.

Bose should have been putting these on factory! Their excellent

Doesn't fit first of all on my Bose earbuds, and second - you have to take the sleeves off when buds go back in the charging pod. Waste of money.

Great fit, looks fine. They do NOT move, which is great only issue is they sometimes don't seat all the way down in the case. You need to push them down until you see the charge light come on

I received these attachments recently and I’m very impressed! They are easy to attach and find the right size. Once they are in your ear, they are very stable. They stay tight, help with ambient noise, and you can jog/jump/etc. exercise with them. And they Do Work in the Charger. That was a big concern of mine ahead of time. I recommend these!

so i really like these, except that "white" is beige and ruins the aesthetics :\ my left ear liked to slip out and that doesn't happen anymore, but the cost is slightly heavier earbuds and more friction against your external ear, so there's a cost there. but yeah it looks like my $200 earbuds are wearing granny panties :( edit: bc i sound unhinged giving it 3 stars over that, added image so you can compare this to the white in the product image

These have completely changed the fit and stability of my QC Ultras. These should be shipped in the box from Bose. Once I got these, no need for third party ear tips to get the sound and stability I wanted

These do help my earbuds stay in more securely, but they are not perfect and I still find myself touching my earbuds to make sure they are still secure. I am still using them and plan to keep using them.
