If you have been in an environment where you couldn't hear sounds for a long time, and then suddenly you can hear them, your brain may not be used to it, and you may feel a little overwhelmed. Consider a break-in period for your ears. Start with short-term use, such as 1 hour on the first day and 2 hours the next day, and gradually increase the wearing time. The discomfort may decrease as you get used to it. 3980r9592
