- A radio headset frees one hand from holding a microphone. Let’s face it, flying is a hands-on activity. Flying from the left seat, in most airplanes, means holding the control yoke or stick in your left hand and the power controls in your right hand. When you use one hand to hold a microphone, you have to sacrifice some control of the aircraft. A headset holds the microphone for you, freeing both hands to do more important work.
- A headset microphone holds a constant position near your mouth, creating consistent transmissions. In contrast, each time you bring a hand held microphone to your mouth to speak, the quality of your transmission will vary with microphone position. It’s nearly impossible to hit the perfect position each time you raise a hand held microphone to your mouth. Turbulence makes this problem even worse.
- The earpieces of a headset protect your hearing. Most headsets use passive noise reduction through insulation, or active noise reduction through electronic circuitry. No matter the method a headset uses to reduce noise, your non-renewable hearing is protected from destruction by high decibel noise. Yes, ear plugs work well, as long as they are 1. fresh and clean, 2. correctly inserted into the ear canal, and 3. you don’t mind feeling like you have head cold while wearing them.
- A well-built headset provides better audio clarity for listening than provided by most cockpit loudspeakers. The earpieces of a headset deliver sound directly to your ear. The sound from a cockpit loudspeaker bounces around the interior of your cockpit and competes with other ambient noises before it reaches your ear.
- A headset gives you an audible sidetone–feedback of your own voice–so you may monitor the quality of your transmission. It’s nearly impossible to hear your own transmission via a cockpit loudspeaker, especially in a noisy cockpit. No feedback equals no opportunity to adjust and improve your transmissions.
- Most headsets have an individual volume control. This means each pilot or passenger wearing a headset can adjust volume to suit his need.
If you have held off buying a headset because you thought they are too expensive, take a look at my Headset Buyer’s Guide. There are headsets in the $100 to $200 range that are very serviceable. You can even get a very well-built headset for under $400.
