A cellular phone speaker and microphone assembly that permits the use of cellular phones in a manner that limits the user's exposure to electromagnetic radiation. The assembly comprises a speaker, a microphone, a first enclosure containing the microphone, a separate second enclosure containing the speaker, and a connecting member, which connects the first and second enclosures in a manner such that an air gap is introduced between the first and second enclosures. Furthermore, the assembly comprises a first air tube extending between the user's mouth and the enclosure containing the microphone so as to transmit sound therebetween and a second air tube extending between the user's ear and the enclosure containing the speaker so as to transmit sound therebetween. The speaker and microphone are individually encapsulated within separate enclosures so as to reduce noise interference between the two devices.
