Charging starts when the headset and the computer are connected. Make sure that the indicator (red) lights up. Charging is completed in about 2.5 hours* and the indicator (red) goes off automatically.

* Time required to charge the empty battery to its full capacity

Notes

• Use the micro-USB cable supplied. You may not be able to charge the headset with other cables.
• If the headset is not used for a long time, the indicator (red) may not light up when you connect the micro-USB cable to charge the headset. In this case, do not disconnect the micro-USB cable from the headset and wait until the indicator (red) lights up.

Tips

• If the micro-USB cable is connected to a computer while the headset is turned on, the headset will be turned off automatically.
• The headset cannot be turned on while charging the battery.

Caution

If the headset detects a problem while charging, the indicator (red) may turn off, although charging is not complete.

Check for the following causes:

• Ambient temperature exceeds the range of 5 °C – 35 °C (41 °F – 95 °F).
• There is a problem with the battery. In this case, charge again within the above-mentioned temperature range. If the problem persists, consult your nearest Sony dealer.

Notes

• If the headset is not used for a long time, the battery may be quickly depleted, however, after a few recharges, the battery life will improve.
• Even if you do not intend to use the headset for a long time, charge the battery to its full capacity once every 6 months to maintain its performance.

What is BLUETOOTH wireless technology?

Bluetooth® wireless technology is a short-range wireless technology that enables wireless data communication between digital devices, such as a computer or digital camera. BLUETOOTH wireless technology operates within a range of about 10 meters (about 30 feet).

Connecting 2 devices as necessary is common, but some devices can be connected to multiple devices at the same time.

You do not need to use a cable for connection, nor is it necessary for the devices to face one another, such is the case with infrared technology. For example, you can use such a device in a bag or pocket.

BLUETOOTH standard is an international standard supported by thousands of companies all over the world, and employed by various companies worldwide.

Communication System and Compatible BLUETOOTH Profiles of the headset

Profile is standardization of the function for each BLUETOOTH device specification. The headset supports the following BLUETOOTH version and profiles:

Communication System:

BLUETOOTH Specification Ver. 3.0

Compatible BLUETOOTH Profiles:

- A2DP (Advanced Audio Distribution Profile): Transmitting or receiving high-quality audio content.

- AVRCP (Audio Video Remote Control Profile): Controlling A/V equipment; pausing, stopping, starting playback, etc.

- HSP (Headset Profile): Talking on the phone/Operating the phone.

- HFP (Hands-free Profile): Talking on the phone/Operating the phone hands-free.

* When you use a BLUETOOTH mobile phone that supports both HFP (Hands-free Profile) and HSP (Headset Profile), set it to HFP.

Notes

SEARCH

- To use the BLUETOOTH function, the BLUETOOTH device to be connected must have the same profile as the headset. Even if the device has the same profile, functions may vary depending on the specifications.

- To use the BLUETOOTH function, the BLUETOOTH device to be connected requires the same profile as that of the headset. Even if the device has the same profile, functions may vary depending on the specifications.

- Due to the characteristics of BLUETOOTH wireless technology, the sound played on the headset is slightly delayed compared to the sound played on the BLUETOOTH device during phone calls or music playback.

- Do not use the BLUETOOTH function on an airplane. The radio waves may cause malfunction of the airplane and result in hazardous accidents.

There are two ways to establish a BLUETOOTH connection: One-touch connection (NFC): You can connect the headset with a device by one touch using the NFC function. [Details] Pairing the headset with a BLUETOOTH device by operating the BLUETOOTH device [Details]

In the case of the one-touch connection, you can perform steps 1 and 2 below by a one-touch operation.

1. Register (pair) a BLUETOOTH device (smartphone, mobile phone, etc.) and the headset with each other.
2. Use the BLUETOOTH device to make a BLUETOOTH connection.
3. Listen to music played on the BLUETOOTH device, or make and receive a call by operating the headset.

The headset supports the following BLUETOOTH version and profiles:

Communication System: BLUETOOTH Specification Ver. 3.0

Compatible BLUETOOTH Profiles: A2DP (Advanced Audio Distribution Profile): Transmitting or

receiving audio content of high-quality.

- AVRCP (Audio Video Remote Control Profile): Controlling A/V equipment; pausing, stopping, starting playback, etc.

* HSP (Headset Profile): Talking on the phone/Operating the phone.

* HFP (Hands-free Profile)*: Talking on the phone/Operating the phone by hands-free.

* When you use a BLUETOOTH smartphone or mobile phone supported by both HFP (Hands-free Profile) and HSP (Headset Profile), set it to HFP.

Notes

• To use the BLUETOOTH function, the BLUETOOTH device to be connected requires the same profile as that of the headset. Even if the device has the same profile, functions may vary depending on the specifications.
• Due to the characteristic of BLUETOOTH wireless technology, the sound played on the headset is slightly delayed from the sound played on the BLUETOOTH device during talking on the telephone or listening to the music.

Using the noise canceling

Set the noise canceling switch of the headset to NC (default setting).

When the switch is set to NC, NC Mode B is set. [Details]

Notes

• The noise canceling circuit actually senses outside noise with built-in microphones and sends an equal-but-opposite canceling signal to the headset.
• The noise canceling effect may not be pronounced in a very quiet environment, or some noise may be heard.
• The noise canceling effect may vary depending on how you wear the headset.
• The noise canceling function works primarily for noise in the low frequency band. Although noise is reduced, it is not canceled completely.
• When you use the headset in a train or a car, noise may occur depending on street conditions.
• Mobile phones may cause interference and noise. Should this occur, locate the headset further away from the mobile phone.
• Do not cover the microphones of the headphones with your hands. The noise canceling function may not work properly.

① Microphone of headphones

- You can also use other headphones than the ones supplied with this headset. When you use headphones not supplied with the headset, the noise canceling function may not work as efficiently as it is designed. If you use any headphones not supplied with this

Using the AI noise canceling

AI Noise Canceling is a useful function that automatically selects one of the noise canceling modes. This function provides the most effective noise canceling mode by immediately analyzing ambient sound components when the noise canceling switch is slid to the AI NC side.

Slide the noise canceling switch to the AI NC side.

When the headset is on, keep the noise canceling switch to the AI NC side until beep sounds come from the headphones. The headset starts analyzing ambient sound components (about 3 seconds). During analysis, sound volume from the headphones is lowered and the indicator blinks.

When analysis is completed, the most effective noise canceling mode is set automatically, and sound volume from the headphones returns to normal.

Noise canceling mode types

NC Mode A	Reduces noise containing a large amount of middle to low frequency sounds. Ambient noise in the environment is effectively reduced.
NC Mode B	Reduces noise containing a large amount of super low frequency sounds. For example, background noise heard mainly on a bus or a train is effectively reduced.
NC Mode C	Reduces noise of relatively quiet and wide range of frequency sounds. Background noise mainly present in an office environment (PCs, copiers, etc.) is effectively reduced.

Note

- The noise canceling mode returns to NC Mode B when: - the noise canceling switch is set to OFF, then to NC again. - the headset is turned off, then turned on again.
