How to Choose the Best CB Microphones?

how to choose best cb microphone

After looking at the assortment of products included in this article, you probably already have a rough idea of what is the best CB microphone for your needs, but there are still multiple other aspects you have to consider to ensure you won’t purchase a model that you can’t use.

Noise Cancelling Ability

There’s nothing worse than having background noise distort what you’re saying on your CB radio, hence why it’s essential to get a mic with noise cancellation properties to eliminate all background sounds when you’re talking. While such models can cost significantly more than a regular model, having your voice come through clearly and loudly makes such an investment more than worth it and will save you from a lot of unneeded frustration.

Compatibility

Nowadays, most leading mics support a broad range of CB radios. However, it’s still vital for you to check if a specific microphone you have in mind can be used with CB radios.

While the majority of modern radios rely on standard connectivity options, there are still some exceptions out there so carefully read the description of each item you’re considering. This will help ensure you don’t waste money on a high-end mic that won’t be compatible with your CB radio.

Sound Quality

Extra features like noise cancellation are great for elevating a CB radio’s audio quality. That said, some of the cheaper microphones boast to have all of the extra features while still offering subpar sound quality in practice, which is why it’s dangerous to estimate the audio quality exclusively on the list of features listed in a product’s description.

Instead, try to evaluate the audio quality of the mic in person. This way you get to find out both how it sounds and how convenient it is to use.

Cable Length and Connector

Most people keep their CB radios next to the glove box or on the dashboard. What it means in the context of picking the best CB microphone is that the mic’s cable should be long enough for you to bring it to your mouth without having to lean towards it.

Most options you’ll find on the market have a cable length between 6-9ft. They also usually come with coiled cords, allowing you to talk through them even if you’re a couple of feet away from the radio. Connectivity-wise, the most popular option for CB microphones is a 4-pin connector, but 6-pin models are quite common as well.
