They don't fit perfectly like the originals that make that 'click', and when they fit because they 'suction', the plastic parts that normally snap the ear tips in place may break during removal

The material is a bit harder than the original, it takes a little more force to "snap" them in, but for Apple AirPods Pro, the Small and Medium sizes do their job perfectly for the money! I recommend them! (Left original - right new)

It does not fasten properly, it does not create the comfortable pressure of the original ones, it is simply not a good product. Avoid it.

They fit normally, I didn't notice any difference in sound and I haven't used them yet beyond the test

I have been satisfied with these. As others have written, they require a bit more force compared to the originals to fit into the AirPods Pro/Pro 2, but on the other hand, this is good, they don't easily come off. In my ears, the size L that I use fits just fine, they successfully pass the ear tip fit test and the active noise cancellation performs the same as the original ear tips. Of course, this is a personal experience, as every ear is different.

None of the sizes (3) of the product pass the headphone test that the phone has when I wear them. The small size of the headphones is similar to the small ones of the originals, but the medium one is the same as the large one of Apple and the large one is even bigger than Apple's. That means the medium size is missing. There is difficulty in attaching the earphone and then difficulty in removing them from the headphones. Also, there are no two small holes at the point of attachment, like in the originals. They feel a bit harder.
Regarding the sound, when I don't use external isolation, sometimes I hear a buzzing noise. In isolation, it's okay. I imagine this is because they are not the ideal size for my ears (I explained earlier that the correct medium size is missing). My headphones are the first-generation Air Pods Pro.
I still don't know how long they will last, I just bought them. I will come back.

I have the AirPods Pro and I bought these because one of mine was broken. These do not fit at all on the AirPods!!! Stay awayyyyyy

Product to avoid. No matter how cheap it is, it's not worth the money. The package contained ear cushions of 3 different sizes (3 pairs) to adjust the AirPods to each ear. Unfortunately, it is made of very poor quality material and within 1 month, 2 out of the 3 pairs became unusable (detached from their base and the AirPods)

It is not compatible with AirPods Pro. Its base is smaller than that of the earphone, it also has a hard plastic with a mesh (unlike the originals that have nothing) which makes the base inflexible and does not fit properly. The holes that theoretically hook the Tip to the earphone are in the wrong position.

Average quality. It is slightly different in size from the regular ones and it ripped after 2 months of use.
