FAQ

General Product Information
01
Are these bone-conducting type earphones?

This product is not a bone-conducting type. Instead, it is an open-ear type that transmits sound by air vibration. PSZ (Personalized Sound Zone) technology allows sound waves to cancel each other out at a set distance from the driver (the source of the sound), preventing leakage of sound to the surrounding environment.

02
Does this product support noise canceling?

The product is an open-ear type that takes in outside noise naturally, and so does not support noise canceling.

03
Can ear cushions be removed and replaced?

Ear cushions cannot be removed or replaced. Forcible attempts to remove the ear cushions may result in damage.

04
There is no sound.
  • Please confirm that the device is securely connected to the device in use.
  • For Bluetooth connection type products, please confirm that the connection is made via Bluetooth. If this is not paired, configure by following the procedure shown here (FAQ_link to pairing method).
  • Check that the volume on your device is not turned down.
  • Restart the audio app that you are using for listening. Restarting the device that you are using, such as the smartphone or PC, may resolve the problem.
05
The sound volume is low.
  • Because this product is an open-ear type affected by outside noise, the listening environment may make it difficult to hear sound from the product.
  • In order to use PSZ technology for sound leakage prevention, playback at a higher volume than regular earphones is required. This is a characteristic of the product, not a malfunction.
  • For wired-type products, depending on the model of conversion connector used, it may result in a lower volume. Either try using a different conversion connector or connect to a device that does not require such a connector, then check how it sounds.
  • This problem may be resolved by adjusting how the product is worn. Check that the product is being worn correctly.

Information on Proposition 65 in the state of California

warning icon

WARNING

Cancer and Reproductive Harm : www.P65Warnings.ca.gov

What is California Proposition 65?

Also known as the Safe Drinking Water and Toxic Enforcement Act of 1986, California Proposition 65 is a law that requires warning to consumers if a product exposes consumers to a wide variety of chemicals known by the State of California to cause cancer, birth defects and/or other reproductive harm. Proposition 65 applies only in California.

Why do we place a Proposition 65 warning on this website?

The Prop 65 warning signifies one of two things:NTT sonority evaluated the product and determined that the product is above the “no significant risk level”
OR
NTT sonority has not evaluated the exposure level of the product, and the warning is provided based on the knowledge about the presence of a listed chemical.

Most NTT sonority products are below the Prop 65 level of concern; however, out of general caution, NTT sonority has chosen to place the Proposition 65 warning on this website.

To learn more about Prop 65, please visit the website of the California Office of Environmental Health Hazard Assessment (OEHHA) : https://oehha.ca.gov/proposition-65
