@Fiona26: I'm really sorry to hear that you have encountered these symptoms while wearing your Galaxy Buds2 Pro. If you are based in the UK or Ireland then please send a private message to Sam_UK by following the steps in the link below, and myself or one of the other mods will be able to get this escalated for you.
I suggest you stay away from this ear bud. I had severe reaction to this for months not knowing that my ear buds pro 2 is having this much debates on causing ear infections.
I have 3 other previous generation galaxy buds, have not had any issues until I started listening with buds pro 2. I cleaned the ear tips with alcohol, submerged it into it, and even used UV light.
My infection healed with 2 weeks of steroid ointment, but the infection and itchiness returned right after only a couple minute using it again.
I may had allergic reactions to unknown materials they use producing it. Cleaning won't help. Just stay away
