Replacement Earmuff Gel Cushions for LINK & Sport DEFY Models

ISOtunes IT-99 Replacement Gel Cushions are designed for users who want a cooler, more comfortable seal on ISOtunes LINK and ISOtunes Sport DEFY BT earmuffs—especially when wearing safety glasses. The soft gel conforms around eyewear temples to reduce pressure points, while the low-profile design helps dissipate heat during hot-weather work. These cushions snap into place for a quick refresh of worn pads, letting crews maintain comfort and fit without replacing the headset they already use on the job.

Each package includes one pair of replacement gel ear cushions. They are purpose-built for ISOtunes LINK models and the ISOtunes Sport DEFY BT. Note that these earmuffs have not been NRR tested with the gel cushions installed. For teams rotating between indoor and outdoor tasks, the IT-99 offers a straightforward way to keep hearing protection comfortable through long shifts and changing conditions.
