Most Blackberry devices comes with a standard 3.5-inch headphone jack that let you listen to music from the built-in mp3 player.
But you can also listen to music without plugging in a cord, by using a wireless bluetooth headset.
Here's a step-by-step guide that will show you how to set up bluetooth on your Blackberry so you can listen to music using a wireless bluetooth headset.
1. Enable Bluetooth on your Blackberry
Click the "Set Up Bluetooth" icon on the main Blackberry screen, and it will automatically enable Bluetooth and start searching for Bluetooth devices that are within range (normally about 30 feet).
Make sure your Bluetooth headphones are in pairing mode so that they can be discovered by your Blackberry. For the Jabra BT620s Bluetooth headphones shown below, this means turning them off and then pressing and holding both sides of the headphones at the same time for about 5 seconds until both sides show solid blue lights.
2. Pair your Blackberry with your Bluetooth Headphones
Once your Blackberry discovers the Bluetooth headphones, it will prompt you to select the device (the headphones). You may already have other Bluetooth devices that you've paired your Blackberry with, such as your computer if it has Bluetooth enabled, but you'll still need to pair with the headphones before you can use them.
Pairing with a Bluetooth device requires establishing a Bluetooth connection that's identified by a unique passkey. You'll always use four zeros "0000" for the Jabra headphones numeric passkey.
