This is the Best AUDIOSYNC 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 on the microphone.

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

Don't ever worry about batteries again! Ok we already know that Martel's HGM-1 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


The HGMUSB has improved audio quality and increased the pickup range to over 3 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 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 7 FEATURE - Live Monitoring, you now can listen through your headsets with the HGMUSB even if you are not recording. Boosting you own hearing by 151%.

The HGMUSB Court Reporter 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 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.

    Posted by on 7th Sep 2016

    I have used Martel for ten years now. My last microphones lasted six years. - How about that? I wouldn't suggest that though. I called and spoke to Jason who was so very helpful and gave me personalized attention and tweaked all my settings. I feel like I have my own built in recording studio now thanks to him.

    I couldn't believe how patient and accommodating Jason was during the set up of my HGMUSB-Mic. He didn't rush me or make me feel inadequate for my lack of knowledge. I learned so much about microphones during that setup. I wish I could go to him for all my technology needs. He's the best!!!

    I bought a new laptop and the recording quality on it was awful. I was desperate for something. This court reporter usb microphone was the answer. Pricey but worth it.

    Posted by on 1st Mar 2016

    It's a little pricey, but worth the money! It makes a very clear recording. This is my second one. I bought it so I'd be sure to have a backup, although my first one is still working just fine. In fact, I just recommended it to a new Official Court Reporter who bought one exactly like it.

  17. 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.

  18. Wow 5 Star Review

    Posted by on 16th Jan 2015

    I have used it on a couple of jobs and the audio
    on CaseCatalyst is superb.

    Would recommend to my colleagues in the profession.

    No battery. Automatically turns on. Quality is excellent.

  21. 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.

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

    Posted by on 14th May 2014

    Great stenograph microphone. I should have bought this microphone years ago instead of struggling through my depositions.

    Posted by on 23rd Apr 2014

    If you are looking for the USB court reporter microphones, LOOK NO FURTHER. The information about court reporter microphones I read on this page has helped me make a decision. I had this USB court reporter microphone now for over a year and love the HD recordings. The HD recordings are a technology update for court reporters.


    Posted by on 23rd Apr 2014

    I have had this court reporter USB microphone for over 2 years now and my Case Audio is perfect. Some of my friends bought low quality microphones and they cant even proof read there transcripts with their audiosyc. Most of them however, now have the Martel USB Court Reporter Microphone and they are loving life. I would plunk down the extra money to get the perfect audio I need. I have been a Certified Reporter over 33 years now and a customer of Martel's since 1983. I only use their equipment.

    USB COURT REPORTER MICROPHONE INFORMATION. I have searched for a special USB court reporter microphone for over 2 months now. I have tried cheap microphones with my audiosync and my laptop and they have all sounded bad. COURT REPORTER/CAPTIONING MICROPHONES. The I tested the Martel HGMUSB, Wow. I have noticed that almost all the Court Reporters in my agency are using Martel microphones and I should have trusted them in the first place. I would recommend the Martel Court reporter microphone to every real-time reporter. Court Reporter microphone for Steno machines and computers with microphone inputs see code 91 HGM1 Court Reporter microphone.

  30. Real time court reporting microphone. 5 Star Review

    Posted by on 23rd Apr 2014

    I have had this microphone for over a year now and love it. I was in court yesterday and dropped it in my glass of water. I let it dry for a day and plugged it in and it works. Wow, Martel wasn't kidding about made in the USA. Its rugged and the sound quality is superior to anything I have heard before in court reporter microphones. I would definitely buy another when I need it.

  31. the HGMUSB court reporter microphone is phenomenal. I'm using Windows 7 5 Star Review

    Posted by on 23rd Apr 2014

    Best windows 7 court microphone for reporters. I love the sound quality. It makes my depo's pop. I can even distinguish between fast talkers. I wish this was available years ago with my old laptop and AristoCAT software. I now do realtime and count on my audio recordings. This court reporter microphone is worth every penny. The best court reporting microphone to use with windows 7.

    Posted by on 23rd Apr 2014

    I just ordered the Elite Court Reporter Microphone HGM-USB HiGain Microphone HGMUSB (NO BATTERY!) Elite Court Reporter from Martel. I am very excited about the fact that it does not take batteries and plugs directly into my computer. I have purchased from Martel during my nine years as a court reporter and have had excellent results with their electronic devices and was worth every single penny. I'm sure that I am going to be 100% happy with the purchase of the Elite Court Reporter Microphone for my AudioSync program on my computer and wonder why I didn't buy this microphone sooner for my AudioSync program. Thanks Martel!

    Posted by on 23rd Apr 2014

    I have been using the Martel HGB-USB mike for the last two years. What a difference it has made! This is well worth your investment. Far superior to any mike I have had in the past. No batteries to remember. The mike is ready to go when you are. Once you use this USB mike, you'll never go back to the old battery-powered mikes again. The sound is incredible. This mike will save you countless hours of frustration. It's the best investment any reporter can make.

  35. Special court reporter microphone 5 Star Review

    Posted by on 23rd Apr 2014

    Special court reporter microphone. I have been a realtime court reporter for 15 years. I had just bought a Toshiba Laptop with Eclipse software. I tried 3 other so called court reporter microphones before I bought the Martel HGMUSB court reporter microphone. Believe me there is a huge difference with the Martel microphone. It also has a green light indicator showing you that it is working properly. I now can pick up voice up to 100 feet, tested. It has an hearing aid ic chip that filters out the back ground noise. Do not waste time or money buy this court reporter microphone, its worth every penny.

  36. The ultimate court reporter microphone 5 Star Review

    Posted by on 23rd Apr 2014

    The ultimate court reporter microphone. I have tried every court reporter microphone in the past. One of fellow court reporters recommended the Martel HGMUSB court reporter microphone. I was skeptical. Wow, It seriously is 10 times more powerful than anything I have ever used. The court reporter HGMUSB even makes my computer run faster. The green light on the microphone was a great idea I just take a look and know it is working right. This should be part of every NCRA member tool box.

    Posted by on 23rd Apr 2014

    It has been nearly 3 decades I have used Martel's Special Court Reporter microphone and I would not trust any other microphone.
