The Eartec ULPSST "Secret Service Type" Headset is the most diminutive headset in the Eartec product line. Instead of a headband, these lightweight headsets include a flexible, clear audio tube with an earbud. The SST also includes a lapel microphone clip with PTT. It can be used with Eartec's SC-1000 Radio, and most Kenwood brand radios. The SST can be a valuable tool in a multitude of applications. Customers currently using the SST run the gamut from ice hockey coaches and equestrian riding instructors to church production teams.
