The blue abalone faceplate is what we went with for the Nio, Universal models don't have customizations. You can check out our custom models and use the configurator if you want to see some options!

@@64Audio thank you. Also, I was wondering does the rate of growth of the ear plateau at any point? Obviously it wouldn’t be a great choice to get a custom IEM for a child, but is there any recorded point at which the size of someone’s ears stops growing?
