Same problem here, ear channels weep fluid and scab over after wearing the Pros less than an hour. Never had such problems before! I will try the Comply tips referenced here, I had similar ones already for my Jabras for better fit and never had issues with them.
In any case, Samsung really should take note, something with their silicone mixture seems highly aggressive.
I've been following similar discussions on the Galaxy US forums where Samsung are asking for more details and in some cases recalling the Buds for further investigation (e.g. https://us.community.samsung.com/t5/Galaxy-Buds/Galaxy-Buds-Pro-tips-allergic-reaction/td-p/1727228/...)
Anyone know how to flag this discussion and issue to forum moderators or someone from Samsung who could help?
I've had the buds and buds + and ended up on antibiotics for reaction. Shouldn't have to buy better tips from elsewhere it's ridiculous this hasn't been addressed by Samsung.. unless it has ?
