[6 Pairs] AZLA SednaEarfit Crystal for Bose Earbuds - Bose Earbuds Replacement Tips - Ear Tips for Noise Cancelling Headphones - for Bose Quietcomfort Ultra Earbuds, Bose QC Earbuds II

The grip is better than the originals so it keeps without falling down. This package came with all the sizes to match different ears, in my case I use two different sizes because my ears are not exactly the same size.

REPLACE Your BOSE With These ASAP..! I was reluctant to try an off-brand with my BOSE earbuds, but I bought these and IMMEDIATELY heard the difference. The standard BOSE earbuds & tips are too thin, it takes forever to find the correct S,M,L, sizing for the best noise cancelling and when found, they still allow random noises to be heard. With these "Off-Brand" tips, I opened the package, selected a size, installed, and all the noises of this world literally disappeared.... These are twice the cost of the oem BOSE tips but definitely worth the extra $$ due to the upgrade in design & durability.. (these will last 2 or 3 x's longer than the BOSe earbud tips)

These earbuds are awesome! They’re super helpful in sealing my ears and keeping them in place. As someone else mentioned, they’re actually a bit bigger than the ones that come with Bose. This is great because my left ear is a bit bigger than my right. The largest size from Bose, the L size, never sat properly in my left ear, and I had to keep adjusting it.AZLA’s L size fits my ear perfectly! Right now, I’m wearing different sizes - L for my left and M for my right. With this setup, the earbuds have never failed Bose’s app earbuds fit test, and I don’t have to keep adjusting them.The only downside is that the material doesn’t seem as soft as Bose’s. But I don’t mind because I can fully enjoy the buds.

I've tried numerous options to try and keep my ear buds in my ears and nothing has worked. I just got these tips yesterday and the difference between these and others are substantial! Where I always needed to use the largest size of any other tips, I only need medium on these, the large are actually too snug and I can hardly place them in my ears! Just that alone blew my mind, but when I started listening to music, audiobooks, videos, etc. that was where these tips really widened the gap. The sound quality thanks to these tips are immaculate! I don't have to worry about sound quality or noise cancelling not working, or my ear buds falling out of my ears anymore!I can't recommend these highly enough! If you're having issues with your ear buds staying in place, look no further than these tips! You'll need nothing else.

Work way better than the Bose ones. Literally seals in my ear and doesn’t work loose. I’m impressed

Update: While my earlier comments were true when I installed and tested them, I was disappointed to learn the next day when I was going to use the earbuds that the earbuds were just about dischargred. The shape of the plastic tip on the earbud itself is oval in shape as are the stock eartips but these are more circular. While they appear to fit, they inadvertently block charging in the case. I do not recommend these.These are just a bit thicker than the stock eartips that come with the earbuds but I think that helps with the seal to keep things nice and silent. I love how the world just seems to disappear when I use these earbuds and these eartips help keep that experience always silent. I really appreciate that there are 6 total sizes so you will find your perfect fit.

Perfect! The original ones kept falling off or falling off when I made my runs but these stay on the ear through everything!

The AZLA medium earbuds fit me the best, but the fit is not perfect. I think I am between the small and medium. Large is definitely too big. I like the clear better than the original white that my QCII came with. I would get these again over OEM replacements.
