Manufacturers pointed out that the Bluetooth headset in the specification, there HandfreeProfile (HFP) and HeadsetPro-file (HSP) are two main factions, decided to headset and cell phone compatibility. The former refers to hands-free function, the latter representing the headset features, consumers have to study their own mobile phones which support standard, and then find the right Bluetooth headset to use.
Bluetooth HFP format which supports more complete phone functions, consumers can set the phone to the headset to operate a good redial, call hold, call reject and other hands-free listening options function. By Nokia, Motorola, Sony Ericsson launched the Bluetooth headset several manufacturers, for example, almost all the main format to support the HFP, there are some models that support both HFP and HSP, consumers should pay special attention to the procurement.
