    My daughter LOVES being able to bring these headphones to school and say she made them. She always surprises her teachers when they actually work!



    My daughter followed all the instructions perfectly. She loved the snarked about sacrificing a headphone set for her to create her own!



    I was thinking of ending my subscription when my son turned 18, but this kit changed both of our minds! Now I’m ordering another kit for myself! Standard headphones are usually too tight. This is very comfortable, it’s cool looking, and the sound is impressive! We may never end our subscription! Way to go Kiwi employees!!! ?????Keep it up!!!

    My 8yo loved this project. She has used them every day since she made them. My husband helped with the instructions but I think she would have figured it out alone too.



    My grandson, who's 10, loved the headphones!



    amazing project. could've used a higher quality speaker.
