Here is tutorial to Pair and connect the headset with your BlackBerry device. Before you can use your headset, you need to pair it with your BlackBerry® device. When you turn on the headset for the first time, it’s already in pairing mode. Once you have decided on a wireless headset, you will need to “pair” it with your phone so it knows where to send the sound signal. To pair your phone with a Bluetooth headset. Please follow the instruction below

1. Tap the “Options” icon on the home screen of your phone. On the Home screen of your BlackBerry device, click the Manage Connections icon > Set Up Bluetooth or Bluetooth Connections > Search.
2. Then Click BlackBerry HS-300.
3. If you receive a prompt to enter a passkey, type 0000 on your BlackBerry device.
4. Then Press the key on the keyboard.
5. When you’ve successfully completed the pairing process, you hear “Connected” through the headset. If you are disconnected, you can press and hold the Call control button for 3-4 seconds to turn on pairing mode at any time.
6. After you finish: To turn off the prompt that appears on your BlackBerry device when connecting and pairing, press the Menu key > Device Properties and set the Trusted field to Yes. For more information, click the Help icon on the Home screen of  BlackBerry device.

The downside of the wireless option is that you have to keep the headset charged, and they can be uncomfortable, especially if used for a long period of time. Another consideration is that wireless headsets may not be so simple to use for the technologically challenged. Wired sets, while not nearly as sleek and glamorous as Bluetooth sets, are simple plug and play devices that rarely fail and are inexpensive to replace.
