Headsets using Bluetooth v1.0 or v1.1 generally consist of a single monaural earpiece, which can only access Bluetooth's headset/handsfree profile. Depending on the phone's operating system, this type of headset will either play music at a very low quality (suitable for voice) or will be unable to play music at all.
The host stack is generally implemented as part of an operating system, or as an installable package on top of an operating system. For integrated devices such as Bluetooth headsets, the host stack and controller stack can be run on the same microprocessor to reduce mass production costs; this is known as a hostless system.
For example, when you use a mobile phone with a Bluetooth headset, the phone uses SDP to determine which Bluetooth profiles the headset can use (Headset Profile, Hands Free Profile (HFP), Advanced Audio Distribution Profile (A2DP) etc.) and the protocol multiplexer settings needed for the phone to connect to the headset using each of them.
