Yes, but it is not as convenient as using MT series headsets.
The difference between MT and HT series headsets is mainly the lack of a built-in boom microphone on the HT headsets. With this boom mic you can clip your radio on your belt, hook it up with the proper PTT cable, then up to the headset. To operate, just push the PTT button on the cable as needed, and the microphone is in place all the time. When you are not in need of communication the boom mic can easily be swung out to the side.
In the HT series headset there is no boom microphone. The headset is connected directly to the two-way radio for incoming audio signal. To talk you have to hold the radio up to your mouth and press the PTT button on the radio. This way it is pretty much like the regular headphones supplied with popular two-way radios and FRS except the HT headset provide hearing protection on top of listening capabilities
