Input: I bought these earmuffs for my son, and I saw a lot of children's headphones, but worried that they were not professional enough, so I chose this professional shooting earmuffs. My son hates a lot of everyday voice. So he is very resistant to going out and unwilling to accept new things. This earphone helps eliminate noise, so that he can participate in activities he usually avoids. You know there'll be annoying noises or crowds, like grocery shopping and hospitals, or when we go to places with lots of young, noisy children. Sometimes, I will use when mowing with a large, very loud zero radius riding mower. I like to wear earplugs under the earmuff so that I can listen to the audio books when harvesting. My other earmuffs hurt the top of my head and my head and ears after a while, pushing my sunglasses. It will become very painful and annoying. This pair is very comfortable (I wear it for 3-5 hours at a time) and is mainly used for hearing protection. They're better than any of my other devices, allowing me to listen to music or books without turning the phone too high, which in some ways undermines the purpose of hearing protection! The only hat they wear is baseball cap, but any head hearing protection I wear is true. I've tried the back of the hood, but they're never fit to stay on, and they're uncomfortable enough to deafen the noise.
Output:
positive
