Edit:* I got a good workout in and run in this morning with the Dunu S&S tips in my Soundcore P40i and they worked great! It's hard to explain....but when I first got my P40i's they fit okay....but once you move around or workout it was like they were trying to push themselves out of my ears....if that makes sense. With the deep fit of these eartips that is not an issue anymore!! Now I love wearing these earbuds again.....I was thinking of giving them to one of my daughters who didn't really want them anyways....but now they are literally loke new to me thanks to these tips. Will definitely be ordering more for some of my other earbuds!*I was having trouble with the fit of my Soundcore P40i earbuds with the stock tips. After reading tons of reviews on reddit to try and find the right fit I took a chance on one or two reviews saying these worked because the spinfit tips thst were recommended were not in stock. So glad I decided to get these! The medium tips fit best (I wear medium tips on every other earbud I own) and they fit fine.....although you have to roll them a bit to get them on.....they are very secure. The extra length allows them to stay in my ears....granted I have not worked out with them yet....but I am confident they will be fine. It greatly improved the sound quality...especially the overall volume and bass....and even though the fit test on the soundcore app says the rught earbud is not secure....it definitely is. If I have any issues after a few uses I will edit the review....but at this time to plan to get several more pair for my other earbuds!!

These are very nice IEM tips that fill a niche in the market; their shape is very unusual and there aren't very many silicone tips out there like this. This shape is much more common for foam tips, so these are an especially strong option for people who find foam tips seal well but otherwise don't agree with their ears.Comfort will very from person to person and IEM to IEM, and two different people will get different experiences with the same IEM as well. If you find that typical bullet shaped tips aren't working well for you, try these instead.I find that I personally have some trouble at times getting these tips into my ears because they're so quick to grip to your ears. Once they're in though the fit is very secure for the same reason, which is a big plus. Just be careful when inserting the IEMs and it'll soon become second nature.These tips also lightly enhance bass, so keep this in mind too before buying them.

Super !

I bought these based on my research for my T10 Planar IEMs as an improvement over the stock ear tips. They seem to have a longer barrel and hence reach further into my ear canal but I don't find that obtrusive and I get a good seal. For this reason, they are definitely an improvement over the stock tips and fit the T10 nozzles well.
