Wireless headphone with ANC makes me feel sick

Hello everyone

My name is Liam and I'd like to report a strange experience I had when using a wireless headphone. Since I lose many headphones for the same reason (cable problems), I decided to buy a wireless headphone this time so that I wouldn't have this problem anymore. I picked the Soundcore Anker Life Q30, some chinese brand, which has ANC technology and some good reviews. I've been hearing about this technology for a while now, but I'd never tried it.

I must admit that the results were the strangest I've ever had when using an electronic product. I noticed two very obvious symptoms. The first is a strange feeling of dizziness, with a slight pressure in my head. The second is a metallic taste in the back of my throat. Both symptoms occur simultaneously and this bad feeling takes hours to go away, and can take up to a whole day to return to normal.

Have any of you ever felt something similar? I did some research and found some cases of people who have problems with ANC, with some reports that it caused nausea and even vomiting or difficulty walking due to dizziness.
