    Note: The Noise Isolation Earbud Tips (for the WF-1000XM4 headphones) will adjust their shape to fit in your ears. Wait for about 10 seconds for the earbud tip shape to stabilize, and then check that they fit firmly in your ears and if the noise canceling effect is sufficient. If you feel the earbud tips don't fit well, or the noise canceling effect is insufficient, remove and reinsert the earbuds, making sure the earbud tips fit snug in your ears.
