A communication device for hearing protection devices provides communication capabilities to users adorning hearing protection devices, which would ordinarily hinder or block communication. The communication device removably attaches to a cup of a hearing protection device and connects to the speakers thereof. One or more wireless transceivers provide wireless transmission of vocal communication and other sound between users of hearing protection devices enhanced with the communication device. Users remain protected by their hearing protection devices and while communicating freely in high decibel environments.
