Its easy to adjust your ISOMAX Headset for a perfect fit.
Make only small changes to start. Bending the headset just enough to feel that you have made a slight bend will make a substantial change in the position of the microphone. The ISOMAX Headset microphone is worn across the back of your head, not across the top, so it does not interfere with your hair. The headband should be just long enough to fit snugly against the back of your head and hook over each ear.

You can adjust the headset to be tighter or looser on your head. It is best to adjust for a slightly loose fit. The extremely light weight of the ISOMAX Headset microphone means it doesnt need to feel tight to stay in place. It will be more comfortable after hours of use if it is not too tight.

Whenever you adjust the length of the microphone boom, you must pull lightly on the cable where it feeds in and out of the tubular part of the headset here. The cable must snake through all the bends in the headset tubing on its way to the microphone and it can jam if it is not kept under tension.

The microphone boom should be adjusted so that the microphone itself is next to the left corner of your mouth and about 3/4 inch away. This is the optimum place for the best sound without picking up P pops and bowing noises. To adjust the boom, push or pull on the movable part here. Push or pull the boom, not the microphone. If you pull the boom off the headband or the microphone out of the boom, you can slide them back together making sure that the front of the microphone (the side with the lighter color screen) is toward your mouth.
