The Sennheiser ME 2 is a miniature omnidirectional electret condenser lavalier microphone, a standard in the industry for discreet and clear speech capture. This model features a locking 3.5mm (minijack) connector, designed to securely attach to bodypack transmitters from Sennheiser and other manufacturers that support this connection type, preventing accidental disconnection during movement. The microphone's omnidirectional polar pattern captures sound evenly from all directions, which is ideal for situations where the speaker may turn their head, though it is best used in controlled, quieter environments due to its sensitivity to ambient noise.

The ME 2 is renowned for its natural, transparent sound reproduction and robust construction. Its small, low-profile design and black color make it easy to conceal on clothing. It includes essential mounting accessories such as a tie clip, clothing clip, and windscreen. Requiring plug-in power (typically 3-5V) from the connected transmitter, the ME 2 is a versatile and reliable choice for broadcast presentations, theater, worship, and corporate AV applications where a discreet, body-worn microphone is needed to deliver clear, intelligible dialogue.
