    Wonderful activity. 12 yr old kiddo LOVED it. We were able to really talk about it and she taught me all about the mechanics and electrical! Great!



    Our grandson absolutely loved building his headphones. And it's been a year and he still uses them daily! So it lasts, is well designed, and provides hours of fun plus his feeling of accomplishment: he tells his friends he made them! So proud!



    This is easily the favorite kit my 12 year old has done! (Close second is the kinetic speaker) The build was challenging and the quality of the headphones is great. He uses them daily for homeschool lessons and they've held up really well.



    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!!!
