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 mic I could find. During my search, I came across some really high quality mics five of which I’ve reviewed here. But before that.
Why do you need a quality cb mic?
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. In addition, being able to speak through the mic 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 upgraded to include better features. Most are also compatible with cbs from different manufacturers.
Top 5 CB Microphone Reviews
Astatic 302-363LB1 Black Noise Cancelling 4 Pin CB Microphone
The 302-363LB1 features a rugged and compact design that blends in well in most vehicles. For exceptional sound clarity, it comes with built in noise cancelling which filters out background noise. In addition, it comes fitted with a low impedance dynamic element for better sound clarity. This makes it a
good choice for radios with PA functionality.
The attached coil cord with 4 pin connector is quite long. It’s also not as thick as cords you’ll find on many competing units. This makes it easy to handle the mic.
Its front steel grille is polyurethane coated. You won’t have to worry about it rusting or breaking in case of an accidental fall.
Workman DM507-4 MIC / Microphone for 4 Pin Cobra Uniden CB Radio
The workman DM507-4 is a good option if you’re looking for an inexpensive but reliable microphone. It comes in a compact and lightweight design that’s easy to handle. The design features a large push to talk button that’s easy to press when you’re transmitting.
One thing you’ll notice about this mic is the plastic body. At first glance you might have the impression that it’s cheap plastic. I had this impression. However, upon handling the mic, I realized that the plastic is tough and you should expect it to withstand knocks without breaking.
The mic is connected to an 8 foot coiled cord. At the other end is a 4 pin connector which attaches to a variety of cb radios from popular manufacturers
like Cobra and Uniden.
Cobra HG M73 70 Series Dynamic CB Microphone
Cobra cb microphones are well known for their innovative designs. The HG M73 70 is no exception. The design features an ABS shell which is tough and durable. It also includes a metal mesh grill which not only adds to the mic’s strength but is also rust proof. A left side push to talk button makes it easy to transmit even if you’re driving.
Connecting the mic to your cb is a 9 foot coiled cord with a 4 pin connector. This makes it compatible with many cb radios from cobra and other brands. It’s worth noting that this power microphone runs on batteries which aren’t provided with your order.
Uniden BC645 4 Pin Microphone for CB Radios
If you own a Uniden PRO500 series cb radio and are looking to replace its stock mic, the BC645 is worth considering. It features a minimalistic design which any cb operator will appreciate. The design includes a large push to talk side button that’s easy to press while transmitting.
The microphones shell is made from high quality ABS plastic which is both durable and break resistant. The shell doesn’t include metal parts so you don’t need to worry about rust.
The Uniden BC645 is also a power mic which requires a single battery to operate. Compared to plug and play mics, the BC645 offers better sound output as the voice signal is amplified before being transmitted. Other features you’ll find on the BC645 include an 8 foot flexible cord with a 4 pin connector.
Ranger SRA-198 Noise Cancelling CB Microphone
The rugged futuristic design is the first thing you’ll notice about the Ranger SRA 198 cb mic. A lot of attention has been placed in creating a cool looking easy to handle mouthpiece.
Like the other mics I’ve included in this review, it includes a side placed push to talk button, a long coiled cable and 4 pin connector. The 4 pin connector allows you to use this microphone with almost any cb radio model on the market today.
It’s a plug and play type of mic meaning you won’t need to invest in batteries to operate. The Ranger SRA-198 also comes fitted with noise cancellation. This will filter out background noise allowing anyone you’re communicating with to hear you clearly.
How to choose the best cb microphone
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’ll 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 are including the noise cancelling 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.
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. In addition, the mic should capture and transmit voice waves clearly. Given the many brands and models on the market today, it can be difficult finding the right one for your needs.
