The Perception Wireless Sports system with its comfortable C 544 L and ultralightweight PT 45 bodypack transmitter ensures maximum user mobility for all handsfree applications. The new C 544 L headworn microphone comes with four moisture shields protecting the transducer from perspiration while you practice your favorite sport. The C 544 L uses the proven transducer of the C 555 L and is quick and easy to put on and replace.

The system comprises an SR 45 receiver, PT 45 bodypack transmitter, universal power supply with US/UK/EU adapter, C 544 L headworn microphone, and one AA size dry battery.

The C 544 L is a head-worn miniature condenser microphone with a convenient behind-the-neck headband. The microphone has a cardioid polar pattern and therefore “prefers” sounds arriving from the front (from the user’s mouth).

The microphone body containing the condenser transducer is shock mounted on the microphone arm in order to suppress cable and mechanical noise. The microphone arm will place the microphone in front of the corner of your mouth to minimize pop noise and protect the microphone from contamination. The supplied windscreen makes the microphone even less susceptible to wind and pop noise. A special moisture shield on the microphone capsule makes it difficult for moisture and makeup to penetrate into the microphone. This barrier prevents the microphone sound entries from being clogged by sweat or makeup which would make the sound dull and reduce the sensitivity of the microphone. Therefore, never remove the moisture shield from the microphone.
