Keep all of these things in mind as you shop. In addition to the basics, most headsets come with one or more additional features. Before buying you should think about how significant these features are to you. Some headsets come with a carrying case to protect your investment. While this may save you a little money on the purchase, you can readily buy headset cases separately and your flight bag may have a headset compartment as well, so this is more of a bonus than a necessity.
Many headsets offer volume controls.
Some models have a single knob on one earcup that controls volume for the unit as a whole. Others offer separate volume adjustments for each ear. Most major headset manufacturers offer a warranty on their products. The warrantees typically range from one to five years, but a few manufacturers offer lifetime guarantees. Check the terms of a warranty to determine exactly what is and is not covered.
