While the microphone is the most complicated part of a noise-canceling headset, there are other features to consider. The headset can either include a single earpiece, often with an ear hook for better stability, or a double earpiece similar to a set of headphones. The single earpiece allows a caller to be aware of what's going on outside the call -- most helpful when you're walking down a busy street. However, the double earpiece allows you to hear a call more clearly, which may be desired in an office setting.
Headset design has come a long way since its invention in 1910 [source: Utah History to Go]. Noise-canceling Bluetooth headsets are available for a variety of models. Sizes continue to shrink and adapt to the changing design needs of the consumer. The Jawbone Bluetooth-enabled headset, for example, is designed to look more like a hair accessory than a phone [source: Aliph Jawbone]. Similarly, the Plantronics Discovery 925 features a diamond-shaped earpiece that looks more like jewelry than a headset [source: Plantronics].
The earpieces in noise-canceling headsets work by sealing off your ear from outside noises. Noise-canceling headsets come with earpieces in a variety of sizes so that anyone can get a perfect ear seal. For more on how noise-canceling works in the earpiece, see How Noise-Canceling Headphones Work.
Most headsets have connectors and adapters, or they can be synced with your Bluetooth-enabled phone. Check with the manufacturer to ensure your phone will work with your headset.
The controls on a headset are typically minimal, since you would use it in conjunction with your regular phone. The controls are typically limited to a "talk" button and an on/off switch for the noise-canceling feature. The noise-canceling feature uses a little extra power, so some users can choose not to use it in every situation.
