5 Best Ham Radio Boom Microphones in 2024

Ham radio, or amateur radio, connects people from across the globe without the need for internet or mobile networks. Whether you’re a seasoned ham or just starting out, the clarity and comfort of your communication rely heavily on your equipment, especially your microphone. A boom microphone, in particular, offers hands-free operation and superior sound quality, making it a staple for enthusiasts who want to chat with ease during long sessions. In this review, we’ll explore the best ham radio boom microphones on the market, helping you find the perfect fit for crystal-clear conversations, whether you’re reaching out locally or touching base worldwide.

When selecting the best ham radio boom microphone, it’s important to consider several key criteria to find a model that suits your specific needs. Here’s a brief introduction to these criteria:

1. Audio Quality: The primary function of a boom microphone is to capture clear, crisp sound. Look for a microphone with a wide frequency response and good sensitivity.

2. Comfort: Since a boom microphone is typically used for extended periods, it should be lightweight and comfortable, with an adjustable design that can accommodate different head sizes and shapes.

3. Build Quality: Durability is key, so select a boom microphone made from robust materials that can withstand regular use and handling.

4. Compatibility: Ensure the microphone can be easily connected to your existing ham radio setup or interface. Check for the type of connector it uses, like a 3.5mm jack, XLR, or a specific brand connector.

5. Noise Cancellation: A good boom microphone should have the ability to filter out background noise, allowing for clear communication even in noisy environments.

6. Price: While you want quality, it’s also important to find a microphone that provides good value for money within your budget.

7. User Reviews: Lastly, look at user reviews to understand real-world performance and any potential issues with the microphone.

With these criteria as a guide, let’s explore the top boom microphones for ham radio enthusiasts.

The Heil Sound PR 781 is a high-quality boom microphone that certainly doesn’t disappoint. Right out of the box, the PR 781 dazzles with its sleek design and robust construction. Made specifically for amateur radio, it brings out the clarity and punch needed for reliable on-air communications. It’s a dynamic cardioid microphone, meaning it’s great at zeroing in on your voice while rejecting sounds from the sides and rear – perfect for busy environments.

In my personal experience, the PR 781 provides a rich, full-bodied audio profile which has been tailored to enhance frequencies typically associated with the human voice. The result is a natural, broadcast-quality sound that cuts through noise and gets your message across with exceptional clarity. Whether you’re chatting on local nets or reaching out to distant contacts during a contest, your voice hits the airwaves with a professional edge that makes a difference.


  • Type: Dynamic
  • Pickup Pattern: Cardioid
  • Frequency Response: 50 Hz to 16 kHz
  • Impedance: 600 ohms
  • Connector: 3-pin XLR

  • The cardioid pattern does an excellent job at noise rejection.
  • The frequency response is tailored for spoken word, creating a smooth, radio-ready voice quality.
  • It’s built like a tank, promising longevity and sturdiness during extensive use.


  • Requires an additional interface or transmitter with a 3-pin XLR for connectivity, which might not be ideal for plug-and-play enthusiasts.
  • Some might find the bass response lacking when compared to other microphones like the Shure SM7B, though this is more subjective and depends on personal taste.
  • While the swivel mount is handy, you’d have to invest in a separate shock mount for absolute vibration isolation.


The Heil Sound PR 781 isn’t necessarily budget-friendly, nor is it exorbitantly priced. It usually retails around the $280 mark, which, for the quality and performance it delivers, is quite reasonable. If you’re serious about your amateur radio pursuits, consider this a worthy investment. Remember, though, you may need to factor in the cost of additional accessories like a boom arm, shock mount, and an interface, potentially pushing your total setup costs up.

My experience with the Shure SM7B was nothing short of impressive. The microphone itself exudes a level of professionalism as soon as you take it out of the box. Its sturdy construction gives it a heft that screams ‘quality’. Once I had it set up in my ham radio setup, the first thing I noticed was its exceptional ability to reject background noise. It does an excellent job at isolating your voice, focusing solely on the sound coming from directly in front of it — which is exactly what you need in an environment where you want your communications to be clear and free of interference.

The sound quality is phenomenal — it captures the natural tone of your voice without adding any noticeable coloration. This flat, natural response is a hallmark of the Shure SM7B, and it’s a big reason why it’s so beloved.
