CB Mic Buying Guide: Factors to Consider

cb mic buying guide

There are some important factors need to consider when you want to buy a CB mic to work with.

The Purpose

First, you need to clearly understand the purpose of the purchase. Why do you want to buy CB radio microphone?

Maybe you want to get a better signal transmission or you often go on long trips and want to anticipate situations when you may need the help of civilization – in general, you should be aware of the purpose of the purchase.


Most microphones are compatible with different brands of CB radio. Therefore, you do not need to worry about whether the microphone is suitable for your radio or not.

But before buying, always check with which radio a microphone can be combined. It will help you avoid embarrassment and waste of money.


All microphones for the CB radio are the same. Installation of microphones to the radio is also the same. For this, there is a connector that must be installed in the corresponding connector on the radio. Where to put the microphone when you do not use it?

You can buy an additional loop and install the microphone there so that it is in a vertical state and does not disturb you (few brands supply microphones with similar settings).

Sound Quality

It is important to choose a high-quality cb microphone that will produce good sound. There are still microphones that produce an echo effect. As a rule, the best cb echo mic is quite powerful and also have an adjustable echo speed.

Choose microphones with volume control because you will definitely need this.


The appearance of all microphones for CB radio is about the same. A microphone, a handset, and a jack are all that 99% of all microphones have. The design is very important for using. The microphone should be ergonomic and light, it will be convenient for you to hold it in your hand and easily manage it. And if management is easy, it automatically becomes safe, which is very important for the road.

Portability, like ergonomics, is the key to security in the case of a microphone for a CB radio that will be used in a car. Most CB mics are small and fit easily in your hand without taking up much space. But if this is not enough for you, you can find wireless microphone models that have a base unit connected to the radio without wires. Wireless CB mic could be very useful.

Noise Canceling

This function must be in your microphone if you want the purchase to be successful. The noise canceling function helps filter out background noise during signal transmission. Therefore, if you have best noise cancelling cb microphone, no extraneous noise will not interfere with your communication.

Cable & Connector

Almost all microphones have cable (with the exception of wireless models). Cable length usually varies between 7 and 9 feet. You can choose the length that suits you. For example, I choose models with a longer cable (spiral shape) because I can use it even at some distance from the radio. If the cable length is 9 feet, you can get out of the car to explore the area and communicate through a microphone.

At the end of the cable must be a 4-pin connector. It is necessary to connect the microphone to the radio.

Power Capability

Surprisingly, a battery is needed to power the microphone, especially if your microphone is pre-amplified. How to identify such a microphone? This model can be identified by the presence of the battery compartment and the volume control.

If the battery is over, you can open the compartment (and sometimes part of the case) and put new ones there. But this does not apply to all models. The lion’s share of microphones takes energy from the radio.


The most common color of microphones is black. In a rare case, you can find red or other bright models. But color is not as important to a microphone as other factors, so brands do not focus on body color.

Uniden makes top quality and best cb radio mic in a completely classic design. As a rule, microphones of this brand are 4-pin and compatible with CB radio. Astatic brand also makes 4 pin microphones. But these microphones are already equipped with a noise-canceling function, which makes the signal quality excellent.

Cobra microphones are distinguished by high quality, rugged housings (metal mesh) and can be compatible with CB radios.


The price of microphones can be completely different – from small to infinity. The difference in prices is always due to the “stuffing” of the microphone. If the microphone is standard and has only a cord and two speakers, such a microphone will not be expensive.

Another thing is a microphone that has many functions and buttons that make it easy to use, and if this microphone has a solid body and a metal grid, then it will have a higher price.

But in this case, you see what you are paying money for. In this matter, the main thing is not to save on quality.

Overview of CB Microphone

best cb micBuy the best mic for CB radio and use it for a long time – the big science. I have met more than once people who were uncomfortable with why I use an additional microphone and do not use the one that was bundled with the CB radio.

It is simple – the microphone with the radio does not have all the necessary functions. For more follow our CB power mic review above.

Why Need A Good CB Microphone?

Good CB Microphone is not a whim but a real necessity.

The fact of the matter is that the world is full of background noises that give off the received signal. The situation gets worse if you are on the road.

Yes, for this there are amplifiers and speakers. But the microphone makes the communication more complete on the radio. Using CB radio without good communication is impossible because your speech will not be transmitted to the other end.

If you want to keep in touch, you can save well by buying  CB microphone and never return to this problem again.

There are other reasons why you need a good microphone. Each of us has a phone that saves us in a difficult moment. But the phone can be left without a signal and this is a very frequent phenomenon on the road.

Having a good microphone can solve communication problems encountered on the road. And you will not need a phone – you can connect via CB radio easily.

And yes, CB radio sets have ordinary microphones. It is like ready-made food in a supermarket — it is there, but it is not cooked from the freshest ingredients. Therefore, if you do not want to get disappointed, it is better to spend money on a quality product.

How to Install CB Replacement Mic

There is nothing easier than installing a CB microphone.

  • As I have already said, each microphone has a cable (sometimes spiral). At the end of this cable must be a connector. Another connector of the same size should be on your radio (this is a special microphone connector).
  • You need to connect this microphone in the same way as you connect the microphone that comes with the microphone. Just plug one connector (from the microphone) into the other (on the radio).
  • Push the CB button on the microphone and check that it is fully turned on.

Safety and Maintenance

In case you want to avoid problems with the microphone, I will advise you to follow these tips:

  • Check all connections
  • It is a good idea to hold the microphone closer to your mouth (especially if it is a noise-canceling microphone) during a call.
  • If your microphone takes energy from the battery, make sure that the battery is fully charged in the microphone. And it is better to have an extra pair of batteries in the car to avoid unpleasant problems.
  • If you see problems with the microphone, check the cord and plugs for defects, maybe some of this is broken.
  • When connecting, be sure to press the microphone button all the way.


FAQ’s on the CB Mics

cb mic faqs

What Type Of Microphone Should I Choose?

You have two choices: a noise-canceling CB microphone or a CB power mic (because these are the two main types of microphones).

When choosing a microphone by type, you need to proceed from the characteristics of your voice. For example, if you have a low voice, I would advise you to take the best CB power mic.

Or if you are often in places of heavy traffic, where there is a lot of noise, the noise cancelling CB mic is more suitable for you.

Where Can I Find A Microphone Stand?

You can find the microphone stand separately based on the size of the microphone you bought. Microphones that include a stand in the kit is very small, so you do not need to count on it when choosing a microphone.

How to test CB microphone?

You can connect the mic to an audio amp and listen in headphones to avoid the speaker. That way you know if the CB mic is working or not.

How to wire a CB microphone?

It isn’t that hard. You need a meter to check you’ve got the right wire connected to the mic. Use the meter to check the reading of each of the wire connectors and you can know where each of them goes.

My CB microphone isn’t working. What could be the issue?

Maybe you’ve got the wrong connections or the plugs didn’t get attached right, which is why you’re facing a problem with the mic.

What makes a CB Mic squeal?

When the CB mic is close to the speaker, that’s when the squeal occurs.

Wrapping Up

Finding the best CB mic is not at all difficult. The main thing to find a compatible microphone of good quality that is suitable for your features (such as voice, for example).

I hope that our review will help you make the right choice. So you can enjoy the high-quality performance of the radio, you will transmit a clear signal without noise, and a new microphone will be useful for you.
