To your Bluetooth headphones in order to communicate with your devices, you need to pair the headphone and also the device. In other situations, the whole process of connecting to some system is called bonding.

As you know, your Bluetooth headphones and your device should be linked up so that they can share information. There are 2 basic methods your devices can connect via Bluetooth. The first is called Legacy Pairing, one other is named Secure Simple Pairing or SSP.

Legacy Pairing will be the method of bonding that devices having lower than version 5.One of the Bluetooth specifications may use for pairing with other devices. For the gadgets to ensure that you pair via Bluetooth, every one must enter a PIN code which fits. Which is, the same PIN has to be entered by both devices. Although PIN codes for legacy pairing could be up to 16 digits in length, some products are able to only as much as 4 digits. Such tools are called limited input devices, and usually, the PIN is proscribed and hard-coded to the Bluetooth device.

Another type of devices that utilizes legacy pairing are the so-called numeric input devices. Mobile phones usually belong to this class. These units can make optimum use of the 16-digit PIN.

A third class of devices using legacy pairing are the alphanumeric input devices. Because the name suggests, such devices can use a mix of alphabetic and numeric characters (approximately 16 characters in length) for that PIN code utilized in pairing. Almost all pcs and smartphones are able to use this input method for pairing.

One other basic method for bluetooth headphones pairing is Secure Simple Pairing or SSP. This technique of pairing Bluetooth devices may be used only for those devices supporting Bluetooth version 2.1 or more. It’s also an even more secure method since it uses public key cryptography to ensure that the bond cannot be hacked into.

Devices capable of Secure Simple Pairing can use four modes for pairing: “Just Works,” Numeric Comparison, Passkey Entry, and Away from Band (OOB). In “Just Works,” the pairing is automatic, with almost no input or intervention from your user. Most Bluetooth headsets utilize this method. In numeric comparison, both devices need to confirm a 6-digit pass code and make sure that the code is identical on devices. In passkey entry mode, a 6-digit code should be entered in order to complete the pairing. In out of band pairing, the devices rely on an external or third-party channel to accomplish the bonding process.

To be able to use your Bluetooth headphones more expertly, you need to understand how a pairing process works. By doing this, you possibly can make the most out of your headphones.
