    Nice! Easy to build!

    12 yo grandson built this in 30 minutes. Sound is good! Wish projects could create more than a single item.

    My 6 year old daughter had a lot of fun making these headphones and tells her friends she made them whenever she's FaceTimeing. She loves wearing them when she does her virtual homeschool classes!

    Great idea not great quality

    My son was so excited to get this project, sadly they didn't last. The clip that holds the headset together broke within a month. He tried to fix it and couldn't. Otherwise it is a great idea

    Great idea, frustrating parts.

    My son was very excited to put together this project. When we opened the package he realized that there was a part missing. We made contact with kiwico and they sent the missing part straight away. The young lady we spoke with at customer service was very nice. Now that the project has been completed for about 6 weeks, he's starting to have issues with the wires not working and the sound going out. I'm not really sure how long it was intended to last. But we did love the idea of him building something functional.

    A fun project with a quality product as the result.

    This headphones are high quality and sturdy construction. My girls 8 and 10 had no issues assembling them with the instructions given.

    Great Activity

    Our son (10) loved putting these together and uses them constantly (they actually work really well, I was pleasantly surprised). Great information on sound as well.

    My son had a blast building, some issues

    My 13 year old son absolutely loved building this kit. It sparked something in him I hadn't seen before and he begged me for another project. Only problem is one of the speakers/headphones keeps slipping off the foam connectors. We are going to try to repair it with left over foam from another kit. If that doesnt fix the issue we may have to glue it. Otherwise it would have been 5 stars.

    My son LOVED this project!

    I surprised him with this box. He was so excited to put it together. One piece was missing, I contacted customer Service and they sent the piece right away.
    My son was able to test it out with the different wire-settings and learned how the wires made the sound selection for each earpiece.
    He even took it to school the next day to show his science teacher and other students. Sound is awesome coming from the headphones.

    kids loved it

    I really like these kits because they learn and they have something that works. They use their kits even days and weeks after they put the kit together.

    Awesome kit

    I bought this for my 9 year old (my husband wanted to make the project with him). He put it all together in about 30-45 minutes without any help. He was so excited when he tested them and they worked. They also sound great too! My son is begging for more kits. Thank you for the wonderful projects!

    Son loved it, but...

    My 13-year-old put it together without difficulty and is using it now. Thank you for creating these educational projects! However, for the place where the headband attaches to the speakers, screws would probably be better than adhesive, to keep the parts together and minimize movement of them.

    It was very easy for my 13 year old son to put together.
