Best Power Mics For CB Radio Reviews

1. Astatic 302-10005 D104M6B – Our Top Choice


  • Good build quality
  • the Clear audio
  • Convenient placement for battery in the microphone
  • Ergonomic design
  • It works well in different temperatures and environments.


  • Small PTT button 
  • No noise canceling. 

For a long time now, Astatic microphones have been an incredibly popular choice for power microphones. So, it shouldn’t be a surprise that the Astatic 302-10005 D104M6B is our top choice for power microphones.

Astatic 302-10005 D104M6B

The microphone has a sturdy build, it features a robust ABS plastic casing, a chrome-plated metal grille, and a sturdy cord that culminates in a 4-pin connector

Though sturdy, the cord is soft. It remains easily pliable even in the cold of winter. The same effect is visible for the PTT button and conventional use of the microphone. Astatic says that the microphone is designed for harsh mobile environments. It certainly appears to live up to the claim. 

The PTT switch here is somewhat small, and almost something like a button. Still, it has that familiar and likable push with a good feel.

All things considered, the microphone has some heft and robustness to it, and feels pretty good in the hands.

Quality has been a highlight of Astatic microphones for a long time. The build quality is good, so is the general circuitry and performance. The sound quality is clear and loud, even without getting the power aspect of the microphone involved. 

If you choose to have some gain in volume, the dial is conveniently located at the back of the microphone. In most cases, users don’t need to crank up the volume knob too far. It works pleasantly well even at lower settings.

Small screws for the battery compartment are visible very close to the volume knob. Removing the screws shows off the circuitry of the microphone and place for the 9V battery. It’s something of a weird placement as the battery needs to be pushed against the circuit board. Being gentle and supporting the board is important, so as not to cause any damage to the circuits.

Amplification and general sound quality work pretty well for the Astatic 302 power microphone. However, there is no noise canceling here. The directional mic helps, but it can struggle in environments with substantial background noise. 

Overall, this is a well-built power microphone with a good performance and a rather accessible price tag. It works well in most environments and remains convenient to handle.

2. Delta M2 – Best Premium Power Mic For CB Radios


  • Remarkable build quality
  • the Clear audio
  • Room in base for customization
  • Works with adapter or 9V battery
  • Convenient to use.


  • The cord length is small
  • No noise canceling. 

Delta M2 is one of the more expensive microphones available for use with a CB radio. It has a rather premium and posh look, but more importantly, it has the features and audio clarity one would expect from a mic in this price range. 

Delta-M2-chrome Power Mics For CB Radio

This is designed as a desktop microphone and it works great with a CB radio base station. You could put it in a vehicle, but the large microphone base makes it preferable for the radio to stay fixed in a spot. Its cord is also relatively short, so there is only so much room to maneuver the position of this microphone.

Having a large base has its advantages. There’s plenty of room for the electronics of the device, or even modifications if you so prefer.

I like the analog VU meter on the base and it does a nice job representing the voice and signal from the microphone. It would have been perfect if the meter was backlit or had a light source. The lack of a light is annoying.

A little below the meter, you’ll find two dials that handle tone and modulation for this power mic. They’re quite easy to adjust to user preference. A small LED between these two dials lights up when the microphone is transmitting audio. 

And then there’s the big red button. Well, this is the PTT button, which is rather large, has a nice visual impact, and feels good to use. Of course, since this is a base mic, you may not want to press the PTT button every time you want to speak.

So, just press it and slide it into the “lock” position, so the button stays keyed. That tiny LED that comes into action to show that the microphone is transmitting is pretty useful in this scenario. It wouldn’t do to forget that the PTT button is pressed and the radio is transmitting!

Of course, right on the top of the base, there’s the mic. It looks quite elegant, somewhat retro, and has a power switch on the stem. More importantly, it does a remarkable job at catching sounds and transmitting them loud and clear. It’s clean-sounding and fun to use.

This power microphone works with a 9V DC supply. An adapter is available in the package for use, though you can get the mic to work with a 9V battery.

Overall, though expensive, Delta M2 is a high-quality power microphone with good looks, good design, and excellent audio quality. It helps that the mic is built like a tank and can be expected to last a long time!

3. Cobra HG M75 – Best Budget Power Mic For CB Radios


  • Attractive pricing
  • Overall good build quality
  • Unidirectional mic for better sound quality
  • volume control for amplifier.


  • A sturdier cord would be better
  • No battery in package.

The simple design and attractive price tag of the Cobra HG M75 make it the microphone of choice for those on a budget. As appearance goes, the mic is in the conventional Cobra style with the logo at the base and a wire mesh grille at the top. 

The PTT button finds its place conveniently to the side and has an overall nice feel to it. Cobra has placed the mic in a sturdy ABS plastic housing, which gives it a sturdy feel while giving it an ergonomic touch. 

However, the same sturdy feel doesn’t extend to the cord. It feels somewhat flimsy. While the four-pin chrome-plated connector itself is sturdy, the cord leading to it doesn’t feel so sturdy.

There is a plastic protector towards the connector end of the cord to offer some support and solace. Although, as things are with this type of protector, it can come loose, thus bringing back the risk to the cord. 

Cobra HG M75

On the plus side, the cord offers a good length, going to almost 9 feet when fully stretched. Of course, practical usage will see it at a lower length, since no one’s comfortable with fully stretching a coiled cord. Yet, the overall length remains convenient and keeps the microphone accessible.

A two transistor amplifier helps the microphone with its power duties. It’s a simple enough design, but pretty useful for a basic powered microphone. 

You’ll need to place a 9V battery inside the microphone to get the amplification working. I’d have preferred the battery to be included with the packaging, just for the sake of simplicity and convenience. 

As a powered microphone, Cobra HG M75 does a pretty good job at amplifying voice and making it sound clearer. On that note, it’s worth pointing out that this power microphone uses a simple amplifier for sound. There is no noise canceling feature for this straightforward budget microphone. 

That means if there is noise in the cabin, it will get amplified along with the voice. Adjusting the mic gain on the radio and the volume on the mic can help slightly with this problem. 

Cobra does offer noise-canceling features for its power mics with the Cobra HG M77 model, but it’s more expensive and I wouldn’t exactly call it a budget option. 

All things considered, Cobra HG M75 is a pretty good budget pick for a power mic. The microphone is well-built and the amplification works as desired. Plus, it feels good in the hand and has a nice heft to it.
