The effect of noise canceling may not be pronounced in a very quiet environment, or some noise may be heard. When you are wearing the headset, depending on how you wear the headset, the effect of noise canceling may vary or a beeping sound (feedback) may be heard. In this case, take off the headset and put it on again. The noise canceling function works primarily on noise in the low frequency band such as vehicles and air conditioning. Although noise is reduced, it is not completely canceled. When you use the headset in a car or a bus, noise may occur depending on street conditions. Mobile phones may cause interference and noise. Should this occur, move the headset further away from the mobile phone. Do not cover the microphones on the left and right units of the headset with your hand, etc. The effect of noise canceling or the Ambient Sound Mode may not work properly, or a beeping sound (feedback) may occur. In this case, remove your hand, etc. from the left and right microphones.

Supported codecs
A codec is an audio coding algorithm used when transmitting sound via Bluetooth connection. The headset supports the following 2 codecs for music playback via an A2DP connection: SBC and AAC.
SBC This is an abbreviation for Subband Codec. SBC is the standard audio coding technology used in Bluetooth devices. All Bluetooth devices support SBC. AAC This is an abbreviation for Advanced Audio Coding. AAC is mainly used in Apple products such as iPhone that can provide a higher sound quality than that of SBC. When music in one of the above codecs is transmitted from a connected device, the headset switches to that codec automatically and plays back the music in the same codec. If the connected device supports a codec of higher sound quality than SBC, you may need to set the device beforehand to enjoy music with the desired codec from the supported codecs. Refer to the operating instructions supplied with the device regarding setting the codec.
