Tango/Sierra "Refresher Kit" (performance ear seals)

FrameFit Ear Seals are designed to hug the curve of the jaw and contain dual-density foam to securely conform around glasses, sunglasses, and hats ensuring more comfort and a better seal for optimal headset ANR performance. FrameFit Ear Seals can be used on all current Lightspeed headsets including Zulu 4, Zulu 3, and Sierra, but they are not recommended for use with Lightspeed Delta Zulu*. The head pad is the standard head pad that comes with the Sierra and Tango headsets. The wind screen (mic muff) fits all current Lightspeed Zulu Series, Sierra, Tango and PFX headset models. All Lightspeed headset mics are calibrated for use with a wind screen. Compatible Headsets: Sierra Tango (legacy) To ensure peak ANR performance and comfort, replace the ear seals, head pads, and mic muffs every 18 months. These are wear items that are not covered by the Lightspeed warranty. *NOTE: FrameFit Ear Seals are not recommended for use with the Lightspeed Delta Zulu as its dynamic ANR system is very finely tuned to the physical properties of the headset including the standard ear seals. Installing FrameFit Ear Seals on your Lightspeed Delta Zulu may affect the performance of the headset.
