No solution!
Today I just got the final "sorry, still not our problem" from our caring friends at Apple after opening a case in spring 2020 and having been treated with the "runaround" for almost a year. Spoken to 10 people. Sent bills from 3 doctors visits, descriptions, changed silicone buds to other brands, cleaned them, thuroughly taped the hoop, used creams, the works. No luck, reaction appears within an hour and irritation/scaling remains for 2-3 weeks after I stop using them. So I have stopped permanently. Obviouly the PBP are at fault. It does not feel right to sell them and just forward the problem.
Anyway, first Apple's escalation-"technicians" concluded it was beacuse I "had not cleaned them", then they said I had to "talk to the shop that sold them", now they say "oh yeah, the materials can cause reaction" but that they are not at fault and it has been written on the website that some materials can cause a reaction. (Which means they can do whatever they like and not be blamed since they "warned me".)
These are some aggressive materials. Never had anything remotely similar with any other products. Never been allergic before. And certainly not to any other in-ear headphones, even sweating.
This apple is rotten. Stay away.
