Lightspeed FrameFit Ear Seals for Zulu / Sierra / Tango Overview:

Lightspeed FrameFit Ear Seals are designed to hug the curve of the jaw for a more comfortable fit and a better seal. The dual-density foam securely conforms around glasses, sunglasses, and hats to help maintain optimal headset ANR performance.

FrameFit Ear Seals can be used on most current Lightspeed aviation headsets, including Zulu 4, Zulu 3, and Sierra. They are not recommended for use with the Lightspeed Delta Zulu headset.

Compatible Lightspeed headsets:

• The Original Zulu by Lightspeed
• Lightspeed Sierra
• Lightspeed Zulu.2
• Lightspeed Zulu PFX
• Lightspeed Tango
• Lightspeed Zulu 3
• Lightspeed Zulu 4

To ensure peak ANR performance and comfort, replace the ear seals, head pads, and mic muffs every 18 months. These are normal wear items and are not covered by the Lightspeed warranty.

Note: FrameFit Ear Seals are not recommended for use with the Lightspeed Delta Zulu. The Delta Zulu dynamic ANR system is finely tuned to the physical properties of the headset, including the standard Performance Ear Seals. Installing FrameFit Ear Seals on a Lightspeed Delta Zulu may affect headset performance.
