Hello in 2024, here's hoping your past allergic reactions have cleared and healed. I found this thread because I am looking to replace my APP 2, which I only just bought. I've had 2 sets of APP 1, and didn't realize my allergic contact dermatitis (ACD) was caused by them. I've been having mild itching and flaking in my ear canal and inside the outer ear for over a year (though I've had airpods pro quite a bit longer - I want to say almost 4 years). Developing the allergic reaction, I really thought it was just psoriasis, but my dermatologist said ACD instead and had me use a 1% hydrocortisone for 2 weeks which helped, but when I stopped using it so that my earphones wouldn't fall out, the reaction returned. Long story short, I realized it was the 'pods. I've known since 2018 I have an allergy to adhesives, and found out from liquid bandages after surgery. (Cyanoacrylate, note "acrylate"). I now have reactions to most bandages aside from hydrocolloid, some silicones, and most products that use a lot of adhesive in production, i.e. cardboard.
Fast forward to now, I am considering trying the Max, but with all the back and forth on this thread and potentially needing to switch earcups right away, I'm much less inclined.
I also have done much more in depth research regarding the allergens that could be causing the ACD. So far the most common I've seen come up is nickel,
acrylates/methacrylates (my suspected allergy to APP), and byproducts of production (also acrylates, etc). I've come across various studies and articles about hearing aids, one about Samsung Galaxy Buds, and another about Airpods Pro and Max (a snipped image of patch testing components from such will be below.)
I really appreciate the in depth testing
@LeonPro. As you were experiencing infections from the sealing off of your ear canal vs. ACD from the pros, I'm hoping I don't have the same allergy to the ear cups, though I feel like I might. I guess for the convenience of the apple universe, it would be okay to find out later and replace the cups than to be disappointed I can't use other over-ear headphones without replacements, etc.
In the patch test photo, it seems the person was allergic to the innermost part of the cushion from the APM, not the mesh or outer part of the cushion, which COULD explain why you (
@LeonPro) only had a reaction when music was playing/air forced from inside, but not from replacement cups that completely cover the memory foam.
Anyway, I thought including this and the link to the article (though it's paywalled) would be helpful for anyone experiencing different allergies. I don't recommend purchasing the article as it's really just a letter to the editor of the journal, but it did have other images and a table. I'm trying to get access again (apparently they give you one-time-access if you got there via google?).
LINK to article.
Hope this helps someone. Good luck out there friends.
