...and by "OEM quality" I mean these are almost as nice as the ear tips that come with higher end IEMs like FiiO, Moondrop, etc.

Yes, Spinfits have nicer construction quality and easier *yet just as secure* mounting to the IEM, on top of that the Spinfit SS size is even smaller than the S from this maker (I have small ear ducts, so this is an issue for me), but overall these are excellent tips at a bargain price, with a nice array of available colors.

Fits and soft feel

I got these earbud tips for a pair of Target Heyday Bluetooth headphones that my girls decided it was fun to peel the tips off of, then proceed to lose. Kids"¦.

Anyway, out of the package, the tips fit no problem! However, the issue came when I had to put them back in their charging case. The tips were too long and wouldn't allow the earbuds to sit on the charging ports right. I checked the tips over and saw it was solid rubber all the way down the length of the tube. Using a utility knife, I carefully cut about 3/16" off the tube and put the tips back on. It was a lot better, but still had some issues sitting on the ports correctly. So, I trimmed them again another 1/8" or so and tried again. Now, they fit in the case perfectly and look good on the earbuds.
Overall, I would have only knocked a half star off for the need to trim that much, but I can only do whole stars, so that is the reason for the 4 instead of 5. These are great tips and if you need some new ones, they work really well. If you find you have the same issue I did with them, just take a utility knife blade and trim off about 1/4" or so and they should work great!

The EarFun Pro 2 has an oval post and the ring in these are circular. It took me a day fighting with it on and off and trying different methods to finally get it onto my earbud.

So, it CAN fit, but you're gonna have to fight for your life to get it on there. I'm a stubborn person and REALLY needed a new tip, so I managed. If you don't want to fight them, I'd skip on these.

Really comfy though, a lot better than the tips that came with the earbuds. If you do decide to get these for the EarFun Pro 2, and manage to get them on, be advised that the case won't shut completely with these on. They still will connect to charge, just the case won't shut completely, it leaves abouuuut a 0.6mm gap at the front.

You could possibly trim the umbrella part towards the back so that it shortens the bud a little and it will close completely, but I am absolutely not trying my luck with taking them off the post and trying again!

I give it 5 stars simply because there are 3 sets of each size of bud tip in the package, which is great. It also held up to me yanking them around, shoving calipers inside of them to try and stretch them, pencils trying to provide an anchor and widen them, they took a heck of a lot of abuse and didn't rip at all.

So really good budget silicone tips if you have a circular post. If you have an oval post, try looking into the SpinFit CP1025 tips.

These fit perfectly for my spouses ear buds. They were easy to install and so far they seem to be good quality. Glad we bought them!
