We refer to the safety regulations and technical information related to Orka Two here.

Safety and health information

Intended use
The Orka Two™ hearing aids are designed for people who have perceived mild to moderate hearing loss.
They are wireless air conduction hearing aids that can be customized to fit the user’s needs.
Indication for use
The Orka Two™ hearing aids are meant to increase the volume of sound for people who have perceived mild to moderate hearing loss. The user can adjust the device according to their individual hearing needs without any pre- programming or hearing test. These hearing aids are designed for direct-to- consumer sale and usage, without the involvement of a hearing care professional.
Hearing health care information
WARNING: People younger than 18 should go to a doctor before using this.
People younger than 18 years old need specialized care, and using this without a medical evaluation may worsen impairment or disability. A hearing aid user who is younger than 18 should have a recent medical evaluation from a doctor, preferably an ear-nose-throat doctor (an ENT). Before using this, a doctor should determine that the use of a hearing aid is appropriate.
WARNING to Hearing Aid Dispensers:
You should advise a prospective hearing aid user to consult promptly with a doctor, preferably an ear specialist such as an ENT, before dispensing a hearing aid if you determine through inquiry, actual observation, or review of any other available information concerning the prospective user, that the prospective user has any of the following conditions:

• Visible deformity of the ear, either congenital or traumatic
• Fluid, pus, or blood coming out of the ear within the previous 6 months
• Pain or discomfort in the ear
• History of excessive ear wax or suspicion that something is in the ear canal
• Dizziness, either recent or long-standing
• Sudden, quickly worsening, or fluctuating hearing loss within the previous 6 months
• Hearing loss or ringing (tinWnitus) only in one ear or a noticeable difference in hearing between ears
• Audiometric air-bone gap equal to or greater than 15 dB at 500 Hz, 1000 Hz, and 2000 Hz

WARNING to Hearing Aid Dispenser, Outputs over 132 dB SPL:
You should exercise special care in selecting and fitting a hearing aid with a maximum output that exceeds 132 dB SPL because it may impair the remaining hearing of the hearing aid user.
Caution: This is not hearing protection.
You should remove this device if you experience overly loud sounds, whether short or long-lasting. If you’re in a loud place, you should use the right kind of hearing protection instead of wearing this device. In general, if you would use ear plugs in a loud place, you should remove this device and use ear plugs.
Caution: The sound output should not be uncomfortable or painful.
You should turn down the volume or remove the device if the sound output is uncomfortably loud or painful.
If you consistently need to turn the volume down, you may need to further adjust your device.
Caution: You might need medical help if a piece gets stuck in your ear.
If any part of your hearing aid, like the eartip, gets stuck in your ear, and you can’t easily remove it with your fingers, get medical help as soon as you can. You should not try to use tweezers or cotton swabs because they can push the part farther into your ear, injuring your eardrum or ear canal, possibly seriously.
Note: What you might expect when you start using a hearing aid
A hearing aid can benefit many people with hearing loss. However, you should know it will not restore normal hearing, and you may still have some difficulty hearing over noise. Further, a hearing aid will not prevent or improve a medical condition that causes hearing loss. People who start using hearing aids sometimes need a few weeks to get used to them. Similarly, many people find that training or counseling can help them get more out of their devices. If you have hearing loss in both ears, you might get more out of using hearing aids in both, especially in situations that make you tired from listening-for example, noisy environments.
Note: Tell FDA about injuries, malfunctions, or other adverse events.
To report a problem involving your hearing aid, you should submit information to FDA as soon as possible after the problem. FDA calls them “adverse events,” and they might include: skin irritation in your ear, injury from the device (like cuts or scratches, or burns from an overheated battery), pieces of the device getting stuck in your ear, suddenly worsening hearing loss from using the device, etc. Instructions for reporting are available at https://www.fda.gov/Safety/MedWatch, or call 1-800-FDA-1088. You can also download a form to mail to FDA.
Note: Hearing loss in people younger than 18

• People younger than 18 should see a doctor first, preferably an earnose-throat doctor (an ENT), because they may have different needs than adults.
• The doctor will identify and treat medical conditions as appropriate.
• The doctor may refer the person to an audiologist for a separate test, a hearing aid evaluation.
• The hearing aid evaluation will help the audiologist select and fit the appropriate hearing aid.

A person who is younger than 18 years old with hearing loss should have a medical evaluation by a doctor, preferably an ENT, before buying a hearing aid. The purpose of a medical evaluation is to identify and treat medical conditions that may affect hearing but that a hearing aid won’t treat on its own.
Following the medical evaluation and if appropriate, the doctor will provide a written statement that the hearing loss has been medically evaluated and the person is a candidate for a hearing aid. The doctor may refer the person to an audiologist for a hearing aid evaluation, which is different from the medical evaluation and is intended to identify the appropriate hearing aid.
The audiologist will conduct a hearing aid evaluation to assess the person’s ability to hear with and without a hearing aid. This will enable the audiologist to select and fit a hearing aid for the person’s individual needs. An audiologist can also provide evaluation and rehabilitation since, for people younger than 18, hearing loss may cause problems in language development and educational and social growth. An audiologist is qualified by training and experience to assist in the evaluation and rehabilitation of hearing loss in people younger than 18.

• When adjusting the volume, turn it up gradually until you reach a comfortable listening level.
• Do NOT use the hearing aids or their components if any part of them is damaged, if they emit loud unusual noise, if you experience a warming sensation, or if you experience a loss of audio. If any of these happen, remove the hearing aids immediately, power them off, and contact the Orka Team for assistance.
