We bought this hearing protection for our 1 1/2 year old son. I wouldn't recommend it for a three-month-old baby because of the pressure. We bought the Alpine Muffy Baby for our 3-month-old daughter. We can recommend it.

There is no case. I always put mine back in the plastic packaging.

Personally, I would not put the hearing protection on a newborn. But I think it is possible if it is really necessary and there is no other option. I wore it for my 8-month-old son for the carnival. I recommend the hearing protection from 6 months.

The product is for children from 6 months. But the scope is not limited. However, the scope is more in the direction of adult hearing protection.

Hello Suitable for children from 0 - 2 years Greetings

We have used the hearing protection with our baby 3m, fits well

This is hearing protection for babies
