An adapter for a wireless communications device has a speaker embedded in an upper end portion, a microphone embedded in a lower end portion, and a male electrical post connector mounted in the lower end portion. The post connector is electrically connected to the speaker and microphone. The post connector has an exposed tip and extends from the lower end portion generally toward the upper end portion. A theoretical plane bisects the base into left and right lateral portions and the microphone and connector are disposed on opposing sides of the theoretical plane. The adapter is configured such that when physically mounted to the wireless communications device, and the post connector is mated to the external communications port, the microphone and speaker are electrically connected to the wireless communications device. The combination may be used for VOIP communications.
