Shure DL4 DuraPlex Omnidirectional Waterproof Subminiature Microphone w/ 3-Pin Lemo

Available in lavalier or headset form, DuraPlex has been extensively tested to ensure an IP57 dust-resistant, waterproof rating*. Whether shooting reality TV, mounting a professional theatrical tour, or wherever audio takes you, contending with the elements won’t slow you down. As comfortable on the beach as it is in a broadcast studio, DuraPlex features a neutral, full sound quality that lives up to the highest audio standards.

The advanced 1.6 mm Shure Plex cable, first introduced with the award-winning TwinPlex subminiature microphone, lasts longer than competing cables due to a dual redundant ground which doubles as a secondary shield. It also offers virtually zero “memory effect,” won’t kink, and is fully paintable.

*IP Code, published by the International Electrotechnical Commission (IEC), rates the degree of protection against dust (first number) and water (second number). An IP57 rating classifies DuraPlex as follows:

  • 5 (Dust) – Ingress of dust is not entirely prevented, but it does not enter in sufficient quantity to interfere with the satisfactory operation of the equipment.
  • 7 (Water) – Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water up to one meter for 30 minutes.


  • 5 mm omnidirectional subminiature design for discrete placement and improved gain-before-feedback
  • IP57 dust-resistant, waterproof rated
  • Neutral, full sound quality for film, broadcast, speech, theater, and performance applications
  • Advanced 1.6 mm Shure Plex cable:
    • Dual redundant ground in cable serves as secondary shield for unprecedented longevity
