This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
NOTE: This unit has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This unit generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this unit does cause harmful interference to radio or television reception, which can be determined by turning the unit off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · Reorient or relocate the receiving antenna. · Increase the separation between the unit and receiver. · Connect the unit into an outlet on a circuit different from that to which
the receiver is connected. · Consult the dealer or an experienced radio/TV technician for help.
This unit must not be co-located or operated in conjunction with any other antenna or transmitter.

The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no proof, however, that these low power wireless devices are absolutely safe. Low power wireless devices emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. The unit has been tested and found to comply with FCC/ISED radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines and RSS-102 of the ISED radio frequency (RF) Exposure rules.
High volume may adversely affect your hearing.

Using only one headset unit
You can remove one headset unit from the charging case and use the headset unit by itself. In this case, only the headset unit that has been removed from the charging case will turn on.
When you remove the other headset unit from the charging case
The connection is automatically established between the left and right headset units, and you will hear the music or other audio on both headset units.
Assigning functions to the buttons of the headset
Depending on the headset unit you are wearing, some functions may not be available in the factory settings. In this case, you can change the function assignments to the buttons using the “Sony | Headphones Connect” app.
Hint
In the factory settings, the music playback function is assigned to the right headset unit. When listening to music with one ear, if only the right headset unit is worn in your ear, use the button on the right headset unit to play music. If only the left headset unit is worn in your ear, operate the connected device to play music. When you play music or other stereo audio while wearing only one headset unit, you will hear monaural sound with the left and right channels mixed. You can also enjoy hands-free calls even when you are using only one headset unit. When you receive an incoming call, answer the call with the headset unit you are using. If you remove the other headset unit from the charging case while you are talking with only one headset unit, you can talk with both headset units.
Note
When you are using only one headset unit, be sure to set the other headset unit into the charging case. When you are using only one headset unit, the remaining battery charge of the headset may be different on the left and right sides.

Checking the remaining battery charge
You can check the remaining battery charge of the rechargeable batteries of the headset and the charging case by the following operations.
If the remaining battery charge of the headset becomes low when the headset is removed from the charging case or while using the headset
If a warning beep sounds and the voice guidance says, “Low battery”, charge the headset as soon as possible. When the battery becomes completely empty, a warning beep sounds, the voice guidance says, “Battery is empty”, and the headset automatically turns off.
When you are using an iPhone or iPod touch
When the headset is connected to an iPhone or iPod touch over an HFP (Hands- free Profile) Bluetooth connection, it will show an icon that indicates the remaining battery charge of the headset on the screen of the iPhone or iPod touch. The display position is an example.
A: Remaining battery charge of the headset B: 100% – 71% C: 70% – 51% D: 50% – 21% E: 20% or lower (requires charging)
The remaining battery charge of the headset is also displayed on the widget of an iPhone or iPod touch running iOS 11 or later. For more details, refer to the operating instructions supplied with the iPhone or iPod touch. The remaining charge which is displayed may differ from the actual remaining charge in some cases. Use it as a rough estimate.
When you are using an AndroidTM smartphone (OS 8.1 or later)
When the headset is connected to an Android smartphone via an HFP Bluetooth connection, select [Settings] – [Device connection] – [Bluetooth] to display the remaining battery charge of the headset as “100%”, “70%”, “50%” or “20%” in the connected Bluetooth device column. For details, refer to the operating instructions for the Android smartphone. The remaining charge which is displayed may differ from the actual remaining charge in some cases. Use it as a rough estimate.
Checking the remaining battery charge of the charging case
If the indicator (orange) on the charging case lights up when both headset units are removed from the charging case, or when the charging case lid is opened or closed with no headset units stored, the remaining battery charge of the charging case is about 20% to 1%. The charging case cannot sufficiently charge the headset with this remaining level of battery charge. If the indicator on the charging case does not light up when both headset units are removed from the charging case, or when the charging case lid is opened or closed with no headset units stored, the remaining battery charge of the charging case is less than 1%. The headset cannot be charged with the charging case in this case.
28

Hint
The remaining battery charge of the headset may be different on the left and right sides depending on how you use them. When checking the remaining battery charge on an iPhone/iPod touch or Android smartphone while using both headset units, the remaining battery charge of the headset unit with less remaining battery charge between the left and right headset units is displayed. When using only one headset unit, the remaining battery charge of the headset unit you are using is displayed. You can also check the remaining battery charge of the headset unit and the charging case with the “Sony | Headphones Connect” app. Android smartphones and iPhone/iPod touch both support this app.
Note
If the headset and smartphone are not connected with HFP, the remaining battery charge will not be correctly displayed. The remaining battery charge may not be properly displayed immediately after a software update or if the headset has not been used for a long time. In this case, repeatedly charge and discharge the battery multiple times to properly display the remaining battery charge.

What is noise canceling?
The noise canceling function generates antiphase sound against outside surrounding noises (such as noises in vehicles or noises from air conditioners indoors) to reduce the surrounding noises by canceling them out.
Note
Depending on the type of noise or if it is used in a very quiet environment, you may not feel the noise canceling effects, or you may feel that some noise is increased. When you are wearing the headset, depending on how you wear the headset, the noise canceling effects may be decreased 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. While 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 microphone part on the left or right headset unit with your hand, etc. The effect of the noise canceling function or Ambient Sound Mode may not work properly or a beeping sound (feedback) may occur. If any of this is the case, remove your hand, etc. from the left or right microphone part.

Supported codecs
A codec is an “audio coding algorithm” used when transmitting sound wirelessly via a 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.

About the DSEE function
The DSEE function complements the high-range sound, which is often lost from compressed sound sources, in the headset to the equivalent of CD sound quality. Sound sources compressed by streaming playback, MP3, Bluetooth transmission codec, etc. are played with natural and expansive sound. The DSEE function can be set up on the “Sony | Headphones Connect” app, and is only available when connected to the headset via a Bluetooth connection. Related Topic

The headset volume during a call and during music playback can be independently adjusted. Changing the call volume does not change the volume of music playback and vice versa. You can also enjoy hands-free calls even when you are using only one headset unit. When you receive an incoming call, answer the call with the headset unit you are using. If you remove the other headset unit from the charging case while you are talking with only one headset unit, you can talk with both headset units.
Note
Depending on the connected device or playback application you are using, playback may not pause even when you receive an incoming call while playing back music. When you receive an incoming call while playing back music, playback may not resume automatically even if you finish the call. Use a smartphone or mobile phone at least 50 cm (19.69 in.) away from the headset. Noise may result if the smartphone or mobile phone is too close to the headset.
