[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

These earbuds are a fantastic alternative to the Bose QuietComfort II. The passive noise cancellation is just as effective, thanks to a great seal. Plus, the tips are compatible with the Bose earbuds, which is a huge benefit given how difficult it can be to find replacement Bose tips.I've decided to switch to these permanently. The original Bose tips have a known design flaw—a fragile silicone strip that holds a C-clip in place, which is prone to breaking. These new tips are a much more durable solution.

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.

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.

I’ll admit I’m a bit surprised. They actually fit and seal way better than the Bose OEM tips. The sound blocking is superior. Very happy.

Good quality Bose earbud tips. There are six different sizes but only one fits. Big negative is the price for basically one set of ear tips. I will buy from Bose from now and on. And I do not recommend these.

These things are the only product that keeps my stupid earbuds in. I've tried several others and they all suck.

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)
