- What it is
- A test-equipment maker's summary of Bluetooth profiles. It describes the Headset Profile (HSP), which carries voice at 8 kHz with the CVSD codec or at 16 kHz with the mSBC codec.
- How much weight it carries
- A vendor summary, not the Bluetooth SIG specification, and it covers HSP rather than the Hands-Free Profile that most earbuds use. Use it only for the sampling rates and codec names, and check the Bluetooth SIG specifications for detail.
