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, the Shure DL4B/O-MTQG-A 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.
