A wireless headset comprises a body portion and a boom pivotably coupled to the body portion. The method comprises preparing the crystalline or polycrystalline wafers by mounting them and machining trenches into the wafers. The selection of a transform function for transforming the coded and modulated sequence of samples may be based on optimizing the transform function for particular operating conditions between the transmitter and receiver. The buffer unit temporarily holds the data therein. When used to analyze signals arriving at a receiver, the method accounts for motion of the receiver, the transmitter, and the signal sources. Fluids, such as air and sound waves, flow through the port at a higher velocity when boundary layer separation is minimized or reduced.
