The Best Elite USB Court Reporter Microphone in the World! 


This is the Best AUDIOSYNC USB Court Reporter Microphone I have ever used, Guaranteed. Do not be fooled by other companies' imitations. There is only one Martel Special Court Reporter microphone. It has a White M on the microphone.
-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 chosen Martel USB microphones which are designed and made in the USA. Live headphone monitoring is included!

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 & Windows 11 & 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 background 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 background 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 an 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 your 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 pickup voice 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 won't 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.

    Super microphone

    Posted by Chris P. on 25th Jun 2022

    So clear I can hear everyone now! I was recommended this microphone by another court reporter and wow was she right. I will always buy from Martel now. They even logged into my computer and checked my settings. Jason told me that court reporters have unlimited help from Martel. Super dupper. I need that.

    Nice Microphone

    Posted by Pamela Stafford on 8th Mar 2020

    This microphone seems to work very well. I was a bit confused by the instructions that came with the microphone because all I had to do was plug it into my computer and it worked. I did not need to do all the other things suggested in the instructions. I like the fact that it doesn't need batteries. Seems very clear.
