This Telex PH - 44 headset comes with a 4 - pin male XLR connector. It's a great pick with a flexible dynamic boom microphone. There's a minor issue where the ear muffs are showing some wear as seen in the photos, but don't worry, the unit still works perfectly.

Using this Telex PH - 44 headset is easy. First, connect the 4 - pin male XLR connector to your audio device. Put the headset on your head and adjust the boom microphone to a comfortable position close to your mouth for clear sound. When using it, avoid pulling on the boom microphone too hard as it's flexible. For maintenance, you can gently clean the headset with a soft, dry cloth. Since the ear muffs are starting to deteriorate, you might want to handle them carefully to avoid further damage. And if you notice any other problems, it's a good idea to check with a professional.
