Best CB Mic On The Market – Microphone Reviews & Buying Guide

December 31, 2018 By Joe Talbert

After several months using the stock mic that came with my truck’s CB radio, it suddenly went quiet. Upon inspection, I noticed that a section of the cable was broken. Since the CB worked just fine, I decided it was more cost effective to invest in the best CB power mic I could find. During my search, I came across some high-quality mics five of which I’ve reviewed here. But before that.

Why do you need a quality CB mic?

The mics that come with a CB radio pack may not do the right job. That’s why we may need to replace CB microphone.

It’s one of the best communication aids for your CB radio

If the person at the other end is to clearly hear what you’re saying, the mic needs to capture the sound waves coming from your mouth. In the case of high-quality mics, they can even cancel out background noise ensuring you’re loud and clear.

Safety and convenience

Where do you prefer to place your CB mic inside your vehicle? Whether it’s the dash or even hanging from the rearview mirror being able to reach it easily is quite convenient. Also, being able to speak through CB radio microphone while holding it with one hand allows you to keep your eyes on the road while driving.

The stock mic isn’t the greatest choice

My CB’s factory installed mic stopped working after a few months. Many manufacturers don’t make an effort to upgrade the factory installed microphones that come with their radios. Many aftermarket CB mics are regularly updated to include better features. Most are also compatible with CBS from different manufacturers.

More qualities of top rated CB mics are:

  • Clear voice transmission
  • high sensitivity and power
  • less interference

How to choose the best CB radio microphone

Mic design

An often overlooked consideration, the mic design plays a huge role on how easy it is to handle. An ergonomic, lightweight design is easier to handle and therefore promoting safety while you’re on the road. Look at the push to talk button. If you handle the mic with your left hand, the button should be placed on the right side of the mic and vise versa.

Cable length and connector

Most CB microphones on the market include a 7 to 9 foot cable. I prefer a longer, coiled cable because it allows me to use the mic even when standing several feet away from the radio. Many new CB radios will connect to a mic via a 4 pin connector. Therefore, always go for mics using this connector type.

Noise canceling and power capability

Many new CB radio microphone models include the noise canceling and power capability feature. Although these might add to the cost of the unit, I have found mics with these features to provide better sound clarity and which is the best CB power mic.

Final verdict

Above all are the best power microphones for CB radio.

There are many reasons why you might want to replace your CB radio microphone. Regardless of your reasons, you will need to find a unit that’s compatible with your CB. Also, the mic should capture and transmit voice waves clearly.

Now, head to the market and get a good CB microphone and enjoy using it. Maybe that’s a great investment which is going to make you love the CB communication more!
