ABSTRACT:
A headset having a built-in memory to store parameter settings relating to headset performance characteristics such as headphone(s) and/or microphone performance characteristics. The performance characteristics can be measured during headset production and stored in the memory. A host adapter may communicate with the headset through a serial communications port of the headset. The host adapter may read the headset performance characteristics and adjust signals transmitted to and received from the headset in accordance thereto. When the headset is used in a system, the system parameters can be manually set and stored in the headset memory. When the headset is used again in the same system, the system parameters can be read from the memory and automatically set. The memory may also store product history information of the headset such as production date, serial and model numbers, and/or any service history.
