How to use the Noise Isolation Earbud Tips

    Using the Noise Isolation Earbud Tips incorrectly can cause quick deterioration or damage of the product. Refer to the following before using the Noise Isolation Earbud Tips:

    IMPORTANT: If the earbuds are cracked, peeled, or deteriorated, refrain from using them and purchase new ones. If the earbuds are not in good condition they may not provide full sound quality or noise canceling performance. Furthermore, wearing cracked, peeled, or deteriorated earbuds may result in earbud fragments remaining in your ear, which could cause injury or illness.

    Removing the earbud tips

    Holding the headphones, gently pull the earbud while twisting and rotating.

    Note: Do not pull on the polyurethane foam portion of the earbud tip. Doing so may cause the earbud tip to be torn or damaged.

    Refer to the following on how to remove the earbud tips (Using WF-1000XM4 as an example):

    • The correct method to remove the earbud tips
    • The incorrect method to remove the earbud tips

    Attaching the earbud tips

    Firmly and completely attach the earbud tips. If the earbud tips are not attached completely, they may come off and adversely affect the sound quality, noise canceling performance, and wearability.

    Check the following:

    • Make sure the earbud tips are not attached in a skewed manner
    • Make sure the earbud tips are inserted firmly all the way

    For how to attach the earbud tips, refer to the following (Using WF-1000XM4 as an example):

    Note: Look in the center of the earbud tip to make sure that the stem color (orange, green, or light blue) cannot be seen. If needed, use a flashlight to make sure the stem color cannot be seen.
    • The earbud tip is attached correctly when the stem color cannot be seen:
    • The earbud tip is attached incorrectly when any part of the stem color (in this case, green) can be seen:

    Cleaning the earbud tips

    • When a Noise Isolation Earbud Tip is dirty, wipe it with a soft dry cloth.
    • Do not wash the earbud tips in water or using a wet wipe. Doing so can speed up deterioration.
      IMPORTANT: Do not use solvents such as thinner, benzene, or alcohol, as they may damage the surface.
    • Be aware that sharp metal objects, nails, adhesive tape, etc. may damage the earbud tips.

    When the earbud tips damaged

    When the earbud tips are damaged, consult a Sony dealer, or purchase the EP-NI1000S, EP-NI1000M, or EP-NI1000L replacement earbud tips (sold separately).

    Notes:
    • The EP-NI1000S, EP-NI1000M, or EP-NI1000L replacement earbud tips may not be sold or supported in all countries or regions
    • The foam materials may become firm at a low temperature. Warm the earbud tips a little with your hands before use
    • When the environmental temperature or usage temperature is high, the polyurethane foam may take time to return to its original shape
    • If you feel that the bass sound has become insufficient (or that the sound quality has deteriorated), exchange the earbud tips with new ones
    • You may hear cracking or popping noises when wearing the headphones. These noises happen because, when wearing or adjusting the position of the headphones, air bubbles inside the earbuds get crushed and restored in response to movements that change the shape of the earbuds. This is normal, and not a malfunction.
    • As the earbud tips fit more snugly in your ears, you may feel a strain to your ears. If you experience discomfort, discontinue use
    • Do not pull on the polyurethane foam portion of the earbud tip. If it is separated from the earbud tip, it will not function
    • Do not subject the polyurethane foam portion of the earbud tip to pressure for over long periods of time. It may cause deformation and it may be difficult to return the earbud tip to the original shape
    • When the earbud tips get soaked, drain the liquid well, and make sure that the earbud tips are dried before use or storage
    • The varying sizes of the holes on the polyurethane foam portion of the earbud tip have no effect on the sound quality
