Understanding Bluetooth Headphones - How to Pair With Your Tool

For your Bluetooth headphones to be able to communicate together with your devices, you need to pair the headphone & the tool. In other situations, the process of connecting to a tool is called bonding.

Legacy Pairing is the method of bonding that devices having lower than version two.1 of the Bluetooth specifications can use for pairing with other devices. For the devices to successfully pair by Bluetooth, each must enter a PIN code that matches. That is, the same PIN must be entered by both devices. Although PIN codes for legacy pairing can be up to 16 digits in length, some devices can only up to four digits. Such devices are called limited input devices, & in most cases, the PIN is fixed & hard-coded in to the Bluetooth tool.

As you know, both your Bluetooth headphones & your tool ought to be linked up so that they can share information. There's basic ways that your devices can connect by Bluetooth. is called Legacy Pairing, the other is called Secure Simple Pairing or SSP.

Another class of devices that makes use of legacy pairing are the so-called numeric input devices. Mobile rings usually fall under this class. These devices can make full use of the 16-digit PIN.

A third class of devices using legacy pairing are the alphanumeric input devices. As the name suggests, such devices can use a combination of alphabetic & numeric characters (up to 16 characters in length) for the PIN code used in pairing. all personal computers & smartphones can make use of this input method for pairing.

The other basic method for Bluetooth pairing is Secure Simple Pairing or SSP. This method of pairing Bluetooth devices can be used only for those devices supporting Bluetooth version two.1 or higher. It is as well as a more secure method because it makes use of public key cryptography to make definite that the connection cannot be hacked in to.

Devices able to Secure Simple Pairing can make use of modes for pairing: "Just Works," Numeric Comparison, Passkey Entry, & Out of Band (OOB). In "Just Works," the pairing is automatic, with tiny input or intervention from the user. Most Bluetooth headsets use this method. In numeric comparison, both devices need to confirm a 6-digit pass code & make definite that the code is the same on both devices. In passkey entry mode, a 6-digit code must be typed in in order to complete the pairing. In out of band pairing, the devices depend on an outside or third-party channel to complete the bonding process.

To be able to make use of your Bluetooth headphones more expertly, you need to understand how the pairing process works. This way, you can make the most out of your headphones.
