control the headset).
The HS-21W headset is compliant with the Bluetooth
Specification 1.1 supporting the following profiles:
Headset Profile 1.1, Handsfree Profile 1.0. However,
interoperability between the HS-21W headset and other
Bluetooth-enabled products is not guaranteed because it
depends on compatibility. Check with the manufacturers of
other devices to determine their compatibility with this
device.
