The EX-507XD is a high-performance lapel microphone that is specially designed for use with Azden's PRO-XD Wireless Microphone System. Tuned for warmer lows and crisper highs, the highly sensitive, omni-directional microphone is engineered to produce a dramatic enhancement in audio quality over the PRO-XD's stock lapel microphone. The TRRS connector also allows the EX-507XD microphone to be used with many mobile devices using video and audio recording apps.
