The Sennheiser ME2 is a compact, omnidirectional electret condenser lavalier microphone designed for discreet, high-quality sound capture in professional wireless and wired applications. Its primary use is as a clip-on microphone for broadcast, theater, corporate presentations, and worship, where clear, natural voice reproduction with minimal visibility is required. The microphone features an omnidirectional polar pattern, which picks up sound equally from all directions, making it forgiving of minor head movements and ideal for situations where the user cannot be perfectly positioned towards a directional microphone. Its small, low-profile capsule is easily concealed under clothing or attached to a lapel, tie, or hairline.

Engineered for reliability and consistent performance, the ME2 operates on standard plug-in power (3-10 V DC) or phantom power (9-52 V DC), provided by the connected wireless transmitter bodypack or a wired microphone power supply. It includes essential accessories such as a windscreen to reduce plosive breath sounds and a variety of clips for different mounting options. The microphone's integrated cable terminates in a common 3.5 mm mini-jack connector (often in a locking configuration for wireless systems), ensuring compatibility with a wide range of Sennheiser and other professional wireless transmitters. Its balanced frequency response delivers clear, intelligible speech while minimizing handling noise.

As a workhorse in the audio industry, the Sennheiser ME2 is valued for its durability, consistent sonic character, and ease of use. It is a standard choice for equipping wireless lavalier systems in news gathering, conference speaking, and performance applications. By providing reliable, clear audio capture in a nearly invisible package, it enables presenters and performers to communicate effectively without being encumbered by a handheld microphone, making it an indispensable tool for professional wireless audio.
