-Tracey, Miami, Florida Certified Court Reporter, Real time.

The #1 Purchased USB Microphone for Court Reporters in the world. Over 33,003 Court Reporters have chose Martel USB microphones which are designed and made in the USA. 

Don't ever worry about batteries again! Ok we already know that Martel's USB court reporter microphone is the best in the world. Here is the next step in court reporter microphone evolution. The HGMUSB is Windows 8, Windows 10 & all versions, XP 32 bit & 64 Bit compatible, Vista 32 bit & 64 and Also the new Windows 7 & Windows 8 32 bit & 64 Bit Compatible. The HGMUSB uses a hearing aid chip and other electronics to actively filter out back ground noises such as air conditioners and paper rustlers. If you are a court reporter you need the Hearing Aid IC chip filter to get rid of back ground noise and track human voices. Now you never have to worry about batteries running out on you during that important depo or murder case. Designed with the elite career court reporters day in mind, we have made the perfect Audio Sync laptop microphone.  

Sample Audio from the Official USB Court Reporter Microphone



I am a licensed court reporter for both Utah and California.  I am currently a working reporter in the State of Utah.  I can't speak highly enough of the Martel products and their ongoing support for court reporters who purchase their products. I purchased both the hand held recorder and the USB external microphone.  Was it an expensive investment?  Compared to the cost to purchase my writer and Case Catalyst software, NO.  I use the hand held recorder as my backup.  The USB external mike is synced to my software.  Fellow reporters:  If you don't have a Martel product and you feel you have "the best quality" external mike and recording equipment, I can tell you without hesitation that you are wrong.  I tried a cheapie external mike that I purchased from Amazon, and I was assured it was great quality.  There is NO COMPARISON to the quality of the Martel products.  NONE.  Any time I need help, the staff at Martel are amazing.  They go out of their way to make sure everything is working properly, and their recording equipment is designed especially for the court reporting industry.  I can't speak highly enough of their products and their support.  Do yourself and your work a favor -- get their recording device and external mike.  You won't regret it.

The HGMUSB has improved audio quality and increased the pickup range to over 6 times that of an average court reporting microphone. During the last couple of years major laptop makers have continually lowered the standards of built-in sound cards, resulting in sound quality problems for our reporters. If your career is counting on the right equipment, you can't afford to be without a HGMUSB Audio Sync microphone!

There are 2 Questions to ask when buying a Court Reporting Microphone:

Is this microphone made in America and does this microphone use an expensive Hearing Aid ultra sensitive IC chip?

The Martel HGM-USB is exclusively made in America and does use a very expensive Hearing AID ultra sensitive IC chip + Noise Canceling technology made specifically for court reporting.

Notice: Official HGMUSB microphones are sold exclusively through authorized dealers.
Accept only the real HGMUSB, it is imprinted on the unit. 

NEW Windows 10 FEATURE - Live Monitoring, you now can listen through your headsets with the HGMUSB even if you are not recording. Boosting you own hearing by 351%.

The HGMUSB Court Reporter USB Microphone has a GREEN LIGHT indicator light that tells you that your microphone is working and recording. This is the only microphone in the world that has a recording indicator light.

The USB microphone goes around the sound card, so if you have a poor sound card it does not matter. 100% digital audio replication. Saving precious processing power for your court reporting software. Martel spent years developing a solution that exceeds the pick up range of the HGM-1. The HGMUSB has a pick-up range of up to 133 Feet (adjustable).

The Martel HGMUSB Digital court reporter microphone has a very special performance advantage. Since the HGMUSB microphone is already sending a digital signal, your laptop wont need to use its Intel processor to change the audio signal to a digital signal. This will save precious computer resources and make your computer faster and more reliable. Especially if you are a real time reporter. Our microphone is compatible with USB 3.0.

Superior Court Reporters in Tucson Testimonial

Jason was professional and was great to work with in ordering the Court Reporter microphones for many Superior Court Reporters in Tucson. This microphone will be an excellent tool for us here. I'm sure we will be back to work with Jason and Martel again. Thank you for working with us, Jason.

    Love this USB Court Reporter microphone.  It works great in depositions and well in court, especially with the microphone stand (Included).  No battery headaches (do I have an extra battery with me) or battery ulcers (is the battery going to go out during this job that is killing me).  I can determine from looking at a popup on my software that the sound is coming through. (The HGMUSB microphone has a heads up Green light indicator on it that tells you it is working) This is my second HiGain court reporter Microphone.   I love it and am getting another.

  1. The best a Court Reporter can buy 5 Star Review

    Posted by on 20th Mar 2019

    I've been through a lot of microphones in my career, even all the new ones being sold on the internet. I bought a very expensive $500 mic from New Jersey and it was terrible. Imagine my surprise when I couldn't return it, what a mistake. There are other companies dedicated to court reporting that sell mics made for us, like the HGMUSB from Martel. It's not a Chinese knockoff like you see everywhere.

  2. Can not tell you in worlds how amazing this court reporter microphone is 5 Star Review

    Posted by on 6th Feb 2019

  4. USB Microphone in court 5 Star Review

    Posted by on 11th Dec 2018

    I want to thank you, Martel, for always coming thru. I'm an official in Superior court and was desperate to find a stand for my mic. I tried everywhere even Amazon. No luck. Then I thought what about Martel, which I had ordered my digital recorder from. Well, you had exactly what I needed and it came in the mail a few days later. I'm up and running with my new stand. Can't thank you enough from all us Court Reporters around the country. Please make sure the Big Bosses get this review. I always highly recommend your products\microphones to every court reporter I know that needs help. Much appreciated and Merry Xmas to all of your staff at Martel.

    Posted by on 23rd Oct 2018

    I was shocked how clear my stenograph recordings sounded. This is the best court reporter microphone, I even heard. I hear my judge sits around 18 feet away from me perfectly now. So worth the money. This is the only USB microphone I will ever buy for court reporting.


    Posted by on 13th Sep 2017

    I'm an official and I needed a microphone that would cut through the "white noise" at the bench, making it possible for me to write using my headphones, without having to get squished between attorneys. This makes trial so much easier!

  35. Official Court Reporter for State of Alambama 5 Star Review

    Posted by on 20th Apr 2015

    I just got a job as an official court reporter. I was having a hard time because the judge that I started working for had all the attorneys come to his bench for all hearings. He speaks with a very low voice and trails off as well. It was very hard for me to hear what the attorneys and the judge were saying because they had their back towards me. I bought this microphone and I am able to hear crystal clear. I do put the earplugs in my ear so I can hear both the judge and the attorneys live.
    The audio sync is great as well.

  36. Wow 5 Star Review

    Posted by on 16th Jan 2015

  39. Exceptional!!!!!!! Court reporters read this 5 Star Review

    Posted by on 27th May 2014

    I have used the HGM-USB for the past week and thought it was awesome and then today happened. A meeting in a lecture hall at LSU. I'm at least 50 feet away from everyone speaking and even with the use of the microphone system, I can barely hear them. The HGM-USB picked it all up, blew my mind. It's not as crystal clear as my regular depos, but I can hear it and make pretty much everything out. Thank goodness because not only did these people talk fast naturally, but they read super fast. I don't know how they did it because quite honestly I never heard them breathe.

  40. Why didn't I get this reporter microphone years ago 5 Star Review
