The Hello Kitty design of the AirPods is very attractive and sophisticated. When first listening to them, you will notice that the material used for the outer shell is black which is very much like a traditional Apple iPhone. However, on closer inspection, you will find that the AirPods are not made from traditional glass like an iPhone, but from a special silicone material that looks a lot like what you would see on an iPod. If you are a collector of toys like me, then you might want to buy one for yourself.
While there are many cases available that look like the Hello Kitty figurines, you might want to stick with a silicon headphone case for the AirPods. These cases have been designed by highly professional graphic artists who know exactly how to match the material used in their products. If you don’t have any cases at all, you could always make a custom case to match the entire look of the AirPods and give it a personalized touch. I personally like to purchase the original artwork of My Melody, the Hello Kitty character, and put that on the case.
