[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

Maybe it's just me, but it seems I can get a better fit with these compared to original equipment. Regardless, it's fiendishly difficult to get a fit that supports the excellent anc of bose buds pro.

These are the best earbuds tips I've ever had. I have odd sized ear canals so the variety of sizes actually managed to get me the perfect fit. The material is also great. It's comfortable and stays in place. I've struggled for years to get earbuds to not fall out while being active and I finally have success with these types.

As advertised, these are high quality silicone. As some have noted on the board, they are not oval, but they mount fine on Bose QCII earbuds. The net effect on the fit is that the tops and bottoms (the "long part" of the oval) is tighter than the sides, but the silicone is thick enough that they fit relatively comfortably. Audio quality and passive noise cancelling are fine.If you have large ear holes, these may not be a good choice for you, as anything larger than medium will cause your earbuds to not fit in the case (at least in the case of my QCII's - maybe on other models it is fine). BTW - I have found that using 3rd party ear tip covers like these https://www.amazon.com/dp/B0CP2BW1S3?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 can improve the ability for the earbuds to stay mounted, and therefore may not need as large of an in-ear size to keep them in place.One other caveat, make sure you have these mounted really well. Because they require some effort to get onto the earbud correctly, a partially mounted one could end up in your ear (almost happened to me). Make sure to give them a good tug before use.These are a little pricey, but the six provided sizes should work for just about anybody (again, though, the large sizes may not work with your charging case). If you have friends with different sized ears than you, you could perhaps trade the extras for a beer or coffee.

These are much more comfortable than what comes on the Bose. I have been using these for a few months now, and I would absolutely purchase them again.

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.

Very nice replacement for old foam tips. Does a much better job of keeping out outside noises.

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.

They are properly hypoallergenic and I like the half sizes. They go on well and stay on. However, they hold on to wax and skin much more than the Bose earbuds, so you have to clean them more often. That's not necessarily a bad thing though.I do think they could be a little more affordable. I don't notice any improvement in sound isolation personally.
