HSP-------------------
A Bluetooth profile (mode) designed to enable a two-way wireless headset to be used with a Bluetooth phone.
Headset is one of the most common Bluetooth profiles. Nearly all phones support it, although some phones only support the very similar Handsfree profile (HFP), which can also be used for headsets.
Headset Profile supports simultaneous two-way (full-duplex) audio, but it does not support stereo audio.
HSP can be used with devices other than phones. For example, a Bluetooth headset could be used with a Bluetooth-enabled PC and VoIP software to place an Internet phone call.
HFP-------------------
A Bluetooth profile (mode) designed to enable a two-way wireless speaker-phone to be used with a Bluetooth phone.
Although it can be used with a desktop speaker-phone accessory, its most common use is with car kits. A Bluetooth car kit will use HFP to connect to a Bluetooth phone, allowing phone calls to take place via the car's audio system (or an installed speaker) while the phone stays safely in a pocket or purse.
HFP is one of the most common Bluetooth profiles. Nearly all phones support it, including ones that do not support Headset Profile (HSP). Since all modern Bluetooth headsets support both HSP and HFP, phones without HSP can still use Bluetooth headsets via HFP.
