A speakerphone typically features a microphone and one or more speakers to facilitate hands-free conversations in group settings. In contrast, a microphone primarily functions as an audio input device, capturing and transmitting sound from specific sources or directions. While speakerphones enable collective discussions without handheld devices or headsets, microphones precisely capture audio from specific points or individuals. These distinct functionalities make each tool valuable in different contexts, catering to various communication needs. Expansion mics complement these devices by expanding their audio coverage and improving the overall quality of group communication in larger or more challenging acoustic environments. For example, Logitech Speakerphone, with noise-canceling technology and instant connectivity, is an excellent choice for business video conferencing, which helps everyone to hear and be heard.
