Welcome to Grouphunt    Learn how it works!
Please note this is a Crowdfunding Hunt. While Grouphunt does not guarantee the promises as advertised by the creator, what we promise is to redistribute the goods to you as soon as we receive them, similar to if you placed the pledge on your own.

Grouphunt deal features ONE ZEROi hat in your choice of color and design. 

Do note that the material of the team color hats will be plain cotton rather than the oil coating. 

 A. Previous products used hard cases. This allowed sound to be reflected and easily heard. In ZEROi’s case, we use a soft cloth material that absorbs leaking sound.

B. Space was limited with other products. A buffer is needed around the bone conduction speaker to prevent any leakage of vibrations. Other products had a difficult time adding this aspect because the case was too small. ZEROi has enough room where the buffer is needed which absorbs the sound.



ZEROi is a hat with four built-in bone conduction speakers. With this technology, you can listen to music or make phone calls, without earphones, while being aware of your surroundings. ZEROi is water resistant, easy to use, and convenient on the go.



  • For the stretch goal you will be able to select your favorite team colors. You will be able to choose when the campaign is over. 
  • When selecting the team’s color, it will be plain cotton rather than the oil coating.



 Bone conduction is a way of transmission of sound. Sound waves are transmitted at a frequency that can be conducted through the bones of the skull. ZEROi doesn’t block the outside sound, so it can used in normal environment conditions.





 ZEROi has four bone conduction speakers, compared to only two from competitors, which allows for an enhance clarity of sound. ZEROi can be worn at any time of the day regardless of the weather condition or the setting. ZEROi allows you to have an open ear which lets you be aware of your surroundings. One charge can last up to 5 hours. Due to the different designs and colors ZEROi offers, it can be worn with any preferred outfit.


















 Backers will receive a limited edition ZEROi. “Backers” will be stitched on the back to show others that you have been supporting us from the very beginning.  

*An email will be sent regarding “backers” stitching option at the end of the campaign



 The use of the high quality oil coating on the cotton makes cap look gorgeous. The material used makes it durable and water-resistant.


 ZEROi can easily be worn anywhere at anytime! The possibilities are endless!

 ZEROi can help you get to your next destination. With the Bluetooth option, use your favorite navigation app and listen to the directions. There is no need to look at your phone because the directions are being told to you.






 With all the technology located in the bill of the cap, it only weighs 1oz (30g) more than your ordinary hat. It is so similar in weight you will not be able to feel the difference.
