Frequently Asked Questions

Q1: How do I use this product?

First apply the Aquasonic gel to the blue circular pad above the earbud.

Then put on the headset, making sure the earpiece is inserted into the right ear. Then start adjusting the headset. When adjusting the headset, the following should be kept in mind:

  • The padding below the headband of the headphones should be centered on the top of the head, without leaning to one side
  • When pulling down the sides, make sure the clamp on the left remains right above your ear
  • The earpiece to the right must be insert into the ear canal and you should feel pressure above your ear canal

After adjusting the headset, plug the USB plug into the battery pack to turn on the headset.

Q2: How do I verify whether the device is working properly?

You should feel a slight pressure above your ear canal and hear a slight buzzing sound when the device is on. This should indicate that the device is functioning properly. If no noise can be head from the headset, please ensure the headset has been adjusted properly and that the battery pack has a charge. If these issues persist, please contact our team at and we will do our best to assist you.

Q3: How long and frequently should I be using the device?

It depends on the individual. Some people respond strongly to the device after 5 minutes of use, while others need up to 30 minutes. We recommend using it 1-2 times per day
