The principle of the bone conduction speaker is that the sound is transmitted via vibration, so with a tighter fit the sound is transmitted better. ZEROi is covered with a soft cloth that absorbs additional sounds which reduces the noise that leaks outside.
After the campaign ends, we will send an email to each backer individually. In the email, you will be able to choose hat type, color options, and ‘backer’ stitching option. If you do not make any selection or you do not reply to the email a black baseball cap with the ‘backer’ stitching on it will be sent to you.
As we developed ZEROi, we originally had a volume button and a touch method. As a result, there were many malfunctions. Due to the structure of the hat, it was difficult to locate these buttons and not visible to the human eye. With this, we decided to add the most accurate mechanical button while the volume and other adjustments can be made easily on your mobile device.
