The DPA 4671 CORE+ Lavalier Microphone is made for situations where you require maximum security and where the visual size of the mic is less important. The Heavy Duty 4671 features a stainless steel housing, a heavy-duty cable relief and a thick 2.2 mm (0.09 in) cable. DPA's Heavy Duty microphones are a more robust version of the original mics they are based upon.
