I had to give up on the AirPod Pro's. Within hours I developed an allergic reaction to the silicone ear tips which I had never had with other ear tips. I had to seek medical treatment. If you go online to the Apple Forum discussions you can see this is a common problem for many. I had to go back to the older plastic ones after my ear canals healed. Apple still will not admit they have a materials issue despite numerous filed complaints. I am sure it will quietly be changed in future models without any acknowledgement.
