If your Xperia is currently connected to a Bluetooth device, the connected device will appear under ' Available Media Devices', as shown in the screenshot below. Also, there’s a limit to how many Bluetooth devices you can pair. Most smartphones can save Bluetooth pairing information for up to eight devices. That limit means your phone will delete the oldest pairing information if you try to pair a ninth device.

With many Sony Bluetooth devices, activating pairing mode is done by pressing and holding the pairing/power button on your device for about 7 seconds. You will often hear an audio cue or see a blue flashing LED to inform you that your device has entered pairing mode. Your device will remain in pairing mode for a few minutes and will turn itself off if the pairing procedure isn't successful.

I can’t find the device in the Bluetooth list: try turning Bluetooth OFF and ON again 

Many new Bluetooth devices (e.g. wireless headphones) automatically go into pairing mode the first time you turn them ON. Your device becomes discoverable on its own. At this point, your device doesn’t have any pairing information saved. However, when you pair a second device, you must manually activate pairing mode. Your device won’t enter pairing mode automatically, unlike the first time. NOTE: For how to enter the pairing mode onyour Bluetooth device, refer to the manual supplied with the product. Bluetooth pairing is similar. When two Bluetooth devices are pairing, they exchange information. They establish a connection and recognise each other in the future without any introduction - unless one device forgets the other one or vice versa.

There are transmitting and receiving Bluetooth devices. Your phone can send music to a speaker, but not the other way around.

If you have paired your Bluetooth device with different devices before, your device may have automatically connected to another device without you knowing it. Make sure you disable that connection before attempting a new one. I'm struggling to connect two Bluetooth devices for the first time or pair a second device. Linking two devices for the first time is called Bluetooth Pairing and is often activated automatically when you're using your product for the first time. We refer to pairing to a subsequent device as 'second-time pairing'. Please continue reading the article below.

You don't even have to power on your headphones. They will turn on automatically.

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: This process can take up to 15minutes. Do not turn off or restart your computer during this process.You can usually find everything you need to know about Bluetooth and your product in its manual.
