Try Out a Phone Headset

For best results, try out a couple of models for a day in real-world conditions; any discomfort should show up quickly.

Make sure the microphone is easily adjusted. Also, not only should you be able to hear your callers without trouble, but they should be able to tune into your voice clearly as well.

The range of volume control does differ across models; make sure to check it is adequate with any set you purchase.
