Heil HTH
Headset Series

The Heil HTH series provides sophisticated, hands-free operation from your HT. Each model features a single-sided, adjustable, lightweight headset that provides clarity and discreet two-way communications. The earpiece can be worn on the left or the right. The gooseneck mic boom is adjustable. There is an in-line PTT switch with lapel clip for secure placement of the PTT.

There are three versions:  HTH-I Icom, HTH-K Kenwood and HTH-Y Yaesu.
Each is prewired with an HT plug to fit many (but not all!) of the handie talkies on the market today.
