Wireless headset having improved rf immunity to rf electromagnetic interference produced from a mobile wireless communications device

The wireless headset according to claim 2S, wherein said inductor comprises a ferrite inductor.

A method of making a wireless headset having improved immunity to RF electromagnetic interference produced from wireless communications devices, which comprises:

• providing a headset body adapted to be worn by a user, a microphone carried by the headset body for receiving voice signals from the user, an earpiece carried by the headset body for directing voice signals into an ear canal of the user, an antenna carried by the headset body for receiving wireless communications signals, RF and audio circuitry connected to the antenna and mounted within the headset body for receiving and transmitting wireless communications signals, and an audio CODEC connected to said REF and audio circuitry and further comprising at least one circuit board mounted within the headset body;
• and
• reducing the RF coupling from a wireless communications device by connecting a filter into audio connection lines formed as signal traces on the at least one circuit board that connect the earpiece and microphone with the CODEC such that each signal trace includes a respective filter serially connected into each signal trace and comprising a ferrite bead formed as a circuit trace and having a length as an overcoat on the circuit trace sufficient for enabling RF suppression.
