The Best CB Microphone
CB World is happy to offer one of the largest collections of CB microphones on the net. Whether you are replacing a worn out mic from the manufacturer, or upgrading to one with a little more style or extra features, we are sure to have what you are looking for. Before you pick a new microphone, there are a few things to consider. You want to have the right pin configuration for sure, but what about an amplified mic? Or Echo? Below you will find definitions and explanations that will help you make an educated choice for the best CB microphone for you.
CB Microphone Features
There are several CB microphones available with special features that distinguish them from other microphones. Some, like echo and roger beep, are more for fun. Others like power and noise canceling features can help you transmit loud and clear.
Power - Power, or pre-amplified, mic's are microphones that require a battery and amplify the audio before it gets to the radio. This is useful for those who speak softly, or may have a weaker signal. These microphones can be identified by a volume knob on the mic (usually on the back) and/or a battery compartment. The battery can be accessed either by a slide-open compartment, or by opening the shell for microphone.
Speaker - Speaker microphones are mic's with the speaker and microphone components in the handset. These types of microphones are typically used with radios developed to work with them. The Cobra PMRSM for handheld CB radios and the Uniden BC906W are examples of these.
Echo - Echo mic's, as the name would imply, produce an echo sound effect. They usually have a volume knob similar to a power mic (echo mics are also considered power mics). Some also have a dial to adjust the speed of the echo. Echo microphones have a battery similar to a power mic.
Noise Canceling - A noise canceling microphone helps filter out background noise while you talk. Some of these mics are identifiable by a curved rubber strip on the front of the microphone. It is common to have to hold a noise canceling microphone closer to your mouth when you talk.
Roger Beep - A microphone with roger beep will transmit a beep when you un-key the mic. This lets the listener know you have ended your transmission.
Wireless - A wireless microphone uses a base box connected to the radio to communicate with the wireless handset. Uniden makes a hand held wireless microphone, while Cobra has a wireless microphone headset.
Hands Free - Just like the bluetooth headsets available for your cell phone, a hands free CB microphone allows you to use your radio without the distraction of holding the mic. Cobra makes a wired and wireless hands free CB microphones
CB microphones are available with two types of cartridges; Dynamic and electret. A dynamic cartridge is ceramic. This type of cartridge is far more common. An electret cartridge is smaller and less expensive. It is a good idea to know which type of microphone your radio uses. One type typically will not perform well on a radio designed for the other.

The most important thing to consider when buying a new mic is the pin configuration. Most newer radios have 4 pin Cobra/Uniden wiring. Some older models have different wiring, though. When you buy a mic, if you're not sure about he wiring, ask a professional before you make a purchase. Some more common pin configurations are shown here:
