NOTE:The second option will reduce your sound quality compared to the first option because it favours signal strength over sound quality.

Frankly, the ZX330BT isn't something we'd feel comfortable tossing into a bag with a heavy 15-inch laptop and taking along with us on public transportation. Sound qualityIf you have previously connected the headset to this BLUETOOTH device, only an HFP/HSP BLUETOOTH connection may be made when the headset is turned on. If this happens, use the BLUETOOTH device and make an A2DP BLUETOOTH connection. For more information regarding Bluetooth connection with Walkman, Headphone, Computer or Sound Bar, refer to: If there is still no audio, try pairing the headset or speakerto another computer or to a cellular phone that has Bluetooth audio streaming capabilities and supports the Advanced Audio Distribution Profile (A2DP).

NOTE: For how to enter the pairing mode onyour Bluetooth device, refer to the manual supplied with the product. When you listen to music from a computer on the headset, sound quality may be poor for the first few seconds after a connection is made. This is caused by the computer transmitting music at sound quality for communications at first, and it is not a malfunction. Due to the characteristic of BLUETOOTH wireless technology, the sound played on this unit is slightly delayed from the sound played on the BLUETOOTH device during talking on the telephone or listening to the music. If the device information of the headphones or speaker is registered to your mobile device, use the following procedure to delete the device information, then reattempt pairing.If the headset detects a problem while charging due to following causes, the indicator (red) may turn off, although charging is not complete. In this case, charge again within the charging temperature range. If the problem persists, consult your nearest Sony dealer. E.g. The WH-1000XM4 wireless Bluetooth headset immediately goes into pairing mode when used for the first time. NOTE: If the device name is not displayed in the Bluetooth items, there is a possibility that the Bluetooth function is set to OFF. Bluetooth speakers and headphones have a pairing button.To activate pairing mode, press and hold the pairing button for several seconds
