Ear defenders for a 3 year old

Some of the manufacturers of ear defenders which are adjustable to accommodate children aged 3+ will recommend something like this:

"For more efficient sound isolation, the earmuffs are a little tight before using. If you feel tight for your kids, we recommend putting it on a box or other objects for 1-2 days to stretch the headband and get it looser."

Maybe an older child could kindly "braak them in" a bit for your 3 year old son.

When I was a child; my family used to include me in tasks around familiar places and people at home or at a relative's house - where everyone nearby the task would be wearing their ear defenders. 

We might be in the house while DIY was happening,  Or in the garden when someone was electric / motor mowing the lawn, or someone was using an electric hedge trimmer, we might be working to maintain a motorbike or repair a car.

I realise your son is only 3 years of age, so safety around such tasks is a consideration.  This sort of thing would happen: one adult would mowing the lawn while the young children would be in the garden up by the house doing some chore with another adult.

This meant I was accustomed to wearing ear defenders around my usual people / places / tasks - I didn't only associate wearing the ear defenders with strange new people / new places / unaccustomed and sensory intolerable noise.

This meant that by the time I wanted to wear ear defenders to noisy events / environments like: a fun fair, traction engine steam fair, steam railway gala, Air Show etc. - I was already an "ear defender wearer pro".

Some of the pairs aimed at aged 3+ are also intended to accommodate a child changing head size as they grow between ages 3 to 16.

This is a popular brand (depending on the colour they are sometimes available on offer for about £10.  The same brand does an adult range and they are popular too):

Thank you for that. I will look into those. I did think about maybe if he saw other people wearing them, would that make them feel more familiar, good idea.
