It is for one year old as stated in the instructions. It is not suitable for a 3-month-old baby as we tried it, it is heavy, the strap comes off, it takes you 2 hours to put it on and the baby cannot sleep on its side so it gets uncomfortable

It is not convenient at all and the elastic is very stiff, I had difficulty putting it on even once and the child was struggling, he didn't keep it on for even 1 minute.

Good fit. It is of good quality.
The downside is that you can't have the baby wear it for more than 1.5 hours continuously.

They seem to provide good insulation because during loud noise the child calms down. They are not always tolerable and certainly their size and pressure do not help, but I don't think it can be any different. If the child tolerates them, they are very effective.

Excellent product, if your child gets used to it, it will take away your worries about what to do in difficult situations such as, for example, a wedding.
I highly recommend it.

We put them on planes and at weddings, she accepted them without complaint and it was very easy to put them on the baby's head. She didn't sleep while using them so I don't know about that

They were purchased for a wedding celebration. They were worn by the baby (2.5 months old) while he was still awake and he fell asleep with them on; otherwise, there was no way he would have slept. He fussed for a few seconds until we adjusted the headband on him. Overall, they saved us; if we hadn't had them, we would have had to leave the moment the couple arrived. The downside is that they are quite bulky, and the baby, while sleeping, wanted to turn his head to the side but couldn't, and he would wake up.

One of the best purchases we've made regarding baby items. We used them on a 3-month-old baby during a logging championship, they isolated the sounds from the chainsaws to such an extent that the baby slept for almost 2 hours. The only downside is that he couldn't turn to the side while sleeping due to the bulk of the headphones, otherwise, value for money is unquestionable! Note: we had put them on while he was awake, we just fastened them in the front.

It provides protection from loud noise to a satisfactory degree and fits well on the baby's head. We used it at a festival with clarinets and he slept just fine!

We wore them for 6 months at a wedding after he fell asleep and the noise didn't bother him!

We were very satisfied. We used them on our 6-month-old baby at a wedding with very loud music (we were very close to the speaker) and he slept undisturbed all night.

Although the sound insulation is satisfactory, they do not stay on the head, the rubber constantly comes off. I do not recommend it

The best purchase I have made for my baby!! We went somewhere with loud music, we put it on our baby and he slept, he generally doesn't tolerate anything on him but the headband is so soft that it didn't bother him at all, he didn't even complain and it is very easy to put it on the baby, you can even put it on while he is sleeping. I highly recommend it, it's worth the money!!

Very good. He wore them at our wedding. At some point when I breastfed him I took them off and he cried. So it probably blocks the sound well

Excellent ear defenders! We used them at the carnival and our babies (10 months old) enjoyed it without being scared of the loud music! It is good to have a couple of practices at home for familiarization. Two people are needed, one to hold the baby and one to put them on.

Very good application. They do not completely limit the sound but they do a good job. We have already worn them at a concert (age 4 months).

It takes two people to put them on (one to hold the child and the other to place them). They didn't seem particularly useful to us because we only used them once, and every other time we tried to put them on, the child would wake up. I don't know if age plays a role, but they were used at 16 months. The price seemed a bit steep to me at 29.90 when we bought them.

I tried it myself to see the difference, the sound is significantly reduced. The best for concerts and events!
