Ear pressure, nausea and sore throat when using the QC35 II headphones
I have the QC35 II headphones since around May this year. At first I felt some discomfort when using it with the ANC: I felt ear pressure and would start getting headaches after a couple of minutes. However, this stopped happening after maybe a week: I would still feel some pressure, but it not longer caused me discomfort.
However, since around 2 weeks, discomfort came back when using the headphones, and it is even worse than it was the first week. I feel more pressure on my ears, which gives me headaches and nausea after a while, but in addition to that, my throat is getting sore, as if it was tightening, and I have trouble breathing normally. The pressure feeling in my ears fades after a few minutes after removing the headphones, but the discomfort in my throat stays for a while, at least 15-20 minutes and sometimes up to an hour. It is a very painful sensation, and I now fear for my health when using the headphones.
I would like to specify a couple of things:
1- The discomfort starts faster when the ANC is set to high, a little slower when set to low and again a little slower when disabled, but almost always ends up happening.
2- I mostly use the headphones for listening to music, but always make sure I'm listening to it at a reasonable volume, between 30% and 40% of the max volume level, maybe 50% in very rare cases.
3- I do use the headphones quite often each day, but usually not for very long each time, and at different moments of the day. For exemple, on a typical day, I would use them from 6:40 am to 8:00 am (so around 1h30) on my way to work, then from 4:00 pm to 5:20 pm (so around 1h30 again) and then usually around 2-3 hours, at home, after 8 pm. And the feeling of discomfort, when it happens, usually starts after maybe 5 minutes and becomes more intense with time.
4- I usually only set the ANC to high when I'm in a very loud place, so usually when when taking the bus and the subway to go to work, and discomfort seem to happen especially often at these moments. The thing is, the point of noise-cancelling headphones is precisely to be used in these kinds of environnement, and yet when the discomfort gets intense, it feels a lot worse when I am wearing them than when I am not and that my ears are exposed to the loud noise.
How can I stop this discomfort from happening? Like I said above, I am fearing for my health when using these heaphones, and it's clearing not normal nor is it acceptable that I am when said heaphones are worth 450$ and are supposed to be top of the line quality and comfort. Had I known that they would cause so much discomfort to me, I would never have bought them, but there wasn't any mention or warning in the official descriptions of the product.
