AirPods Pro has strong strange smell.

I bought AirPods Pro just few days ago.

I feel strong strange chemical smell from earchip silicon.

I feel sweet smell, but it’s strange , bad smell and sometimes nausea.. I like this product very much, but I can’t accept this smell.

But new silicon chips don’t have bad smell.

I feel the smell going to be strong and strong by charging.

This is just my guess. The chemical smell is maybe hydrogen fluoride from lithium bottom battery which inside of AirPods Pro. Maybe during changing, gas from battery move to silicon chip? Because, at my company we use lithium battery and company tell us hydrogen fluoride is very very dangerous chemical for human and the smell is sweet.....

This is just my guess. But I hope apple company verify this problem for safety of health problems.

I would like to know every AirPods has the smell? What is this smell from? Not good for health? Apple think this is big problem or just normal for this product?
