In short, yes.

You headset is compliant with Bluetooth Specification 3.0 supporting the following profiles: A2DP (1.2), HFP (1.6), HSP (1.2) and AVRCP (1.4). The wireless connection works with all devices, such as phones, computers or music players with these profiles.With wireless connection, the key presses are always the same, regardless of the connected device.

The wired connection works with most devices with the 3.5 mm audio connector. However, with Nokia Symbian, Nokia S40 and Nokia N9 phones, the wired connection does not work. Also note that with wired connection the key presses may vary according to the device.
 

With a wireless connection, the fully charged battery has power for up to 10 hours of talk time or 24 hours music playing time, or up to 7 days of standby time.

With wired connection, the headset does not use battery for the connection connection at all, so you can use it even if the battery was empty. However, some features, such as Active Noise Cancellation (ANC) may not be available until you recharge the battery.

Nokia S40, Nokia Symbian and Nokia N9 phones have Nokia AV connector, which is not compatible with the TRRS connector of your headset.

You need to switch on the multipoint connection first.

1. Make sure the headset is switched on, and press and hold the Bluetooth key for 2 seconds.
2. Press and hold the volume up key and fast-forward key to switch the multipoint feature on.

Switching the headset or ANC on or off are built in to the mechanics of the headset. Folding the headset open switches it on, and the proximity sensors on the earpieces switch ANC on when you put the headset on.

When the battery gets empty, the headset switches off the wireless connection and the Active Noise Cancellation (ANC). You can continue using your headset with the wired connection. Note that some features may not be available with the wired connection.

Yes. You can use the headset on a plane with the wired connection. When you connect the audio cable to the headset, it automatically switches the wireless connection off. Make sure you also set your phone to flight mode.
