A connector for providing audio signals to reduce noise during transmissions. A multi-pin connector receives audio signals and a ground, power, and audio signal connector transfers the audio signals to a noise-reduction device. An audio output transfers audio signals from the multi-pin connector to an in-ear system and at, least one ear-protection device. A multi-pin signal separator in communication with the multi-pin connector, the ground, power, and audio signal connector, and the audio output can receive all or a portion of the audio signals from the multi-pin connector, the ground, power, and audio signal connector, and the audio output and can selectively pass the audio signals to at least one of: the in-ear system and the at least one ear-protection device, while accepting a plurality of pin configurations.
