Before You Use the Noise Canceling Headphones

❑ You can enable the noise canceling function only when the supplied noise canceling headphones are connected to the headphones jack that supports this function.

❑ The noise canceling function does not work on sound output with the following devices:

❑ External speakers

❑ Headphones without the noise canceling function

❑ Sound output devices connected to your computer via a Bluetooth connection

❑ The noise canceling function cannot be fully in effect unless you properly wear the headphones. Be sure to fit earpieces of the headphones tightly into your ears.

If you feel that the noise canceling function has little effect, adjust the earbud position in the earpieces of the noise canceling headphones or replace the earbuds with a pair in another size. A pair of medium-size earbuds is attached to the earpieces by default and there should be an extra pair in each small and large sizes supplied with the headphones.

❑ The noise canceling function is to reduce low-frequency noise in the ambient environment but not high-frequency noise.

Nor is it to implement a 100% noise-free audio environment.

❑ You may hear a soft hissing noise while the noise canceling function is enabled. This is just operational noise that the function generates and does not indicate a malfunction.

❑ You may feel that the noise canceling function has little effect or ambient noise seems even louder, depending on the type of noise or the degree of quietness in your environment. In such a case, disable the noise canceling function.

❑ Use of a mobile phone may cause radio interference with the noise canceling headphones. When using the headphones, keep mobile phones away from the headphones.

❑ Plugging or unplugging the noise canceling headphones generates noise. This is normal and does not indicate a malfunction. Be sure to take off the headphones from your ears before plugging or unplugging the headphones.

❑ Enabling/disabling the noise canceling function or enabling/disabling sound with the Windows volume controls generates noise. This is caused by switching the noise canceling circuit and does not indicate a malfunction.

❑ Be sure to use the supplied noise canceling headphones. You can plug the headphones supplied with a Walkman ®

to your computer but the noise canceling function of the computer will not work well with such headphones.
