Aiivioll [3 Pairs] Ear Tips Covers for Bose QuietComfort Ultra Earbuds (2023), Anti-Slip Silicone Sports Wing Tips, Washable Eartips Accessories (Black, S/M/L)

These are a great upgrade for the Bose earbuds. The glorified rubber bands that the earbuds ship with from Bose are a real weak link for an otherwise great pair of earbuds. The Bose ones are constantly slipping and rotating - really bad design. These replacements fit snuggly and are held in place by design - with a hole for the microphone.

I could not get this to fit on the Bose QuietComfort Earbuds II. The width of this product is about 3x the Bose version. I could not get it to fit properly. I've since realised that Bose sells different ear tip covers for the Bose QuietComfort Earbuds II and the Bose QuietComfort Ultra, therefore, unlikely to have a product that can fit both.

Really good fit. Very happy with this item

Tried multiple eartips, and these are by far the best. The stock ones kept slipping, but these keep my Bose QC Ultra earbuds secure, even when moving around. Better fit, better seal and way more comfortable. Highly recommend!

These earbud covers fit my Bose Quiet Comfort Ultra Earbuds very well, provide a very secure and stable fit, but the material is not comfortable in my ears at all, and thus I cannot wear them at all, shame because they do provide a very snug and secure fit, but the Bose original stabiliser wings are much better and comfortable material.

Does not fit bose quietcomfort ultra earbuds.

Good product. I thought these were better than the ones supply by Bose

They stick. The trick is to know your earpiece size really
