Quick Overview

The most powerful USB Microphone on the market & includes auidosync radio filter!

Unlike most other USB Microphones on the market, which have short cables, or no cables at all (keeping the microphone VERY close to your laptop), the Martel HGM-USB 2.0 court reporter microphone was specifically designed to have a 3-foot cable. This allows you to extend the microphone away from typical laptop noise: fans, processor, hard drive spinning, and typing (keyboard clicking) which can affect your recording.

The HGM-USB has all the advantages of the Martel original HGM-1 Microphone, but doesn't need batteries or even a good internal laptop sound card. The HGM-USB microphone bypasses your laptop's internal sound card, so a poor laptop sound system no longer matters. The Martel HGM-USB has 100% digital audio replication (all audio processing is handled by the microphone, NOT the computer) which saves precious processing power for your court reporting software. Martel spent years developing a solution that exceeds the pick-up range of the original HGM-1. As a result, the HGM-USB has an omnidirectional range of up to 75 Feet.

eVerbatim Exclusive Inclusion - Audiosync Radio Filter!

What's the point in having the absolute BEST microphone on the planet for court reporting if you're still subject to the SAME radio interference that ALL microphones are? While we couldn't come up with a good answer, we did come up with a GREAT solution. All Martel HGMUSB microphones purchased from eVerbatim now INCLUDE the Martel Audiosync Radio Filter at NO EXTRA CHARGE! This $49 optional device is ONLY included with purchases made from eVerbatim, and we still give you a free tripod to mount the microphone to and a free pair of headphones for duplexing.

The Martel HGMUSB digital court reporter microphone has a very special and distinctive performance advantage. Unlike other USB Microphones which require your laptop to convert their analog signal to a digital one, the HGMUSB microphone is already sending a digital signal - meaning your laptop won't need to use it's processor to convert the audio signal from analog to digital. This will save precious computer resources and make your computer faster and more reliable, especially if you are a real time reporter. 

Each HGMUSB is hand built, just like a Rolex watch, here in the United States and is tested in Martel's California facility to meet or exceed their industry-leading quality standards. They use an exhaustive 29-point evaluation system to make sure each microphone meets or exceeds your requirements.
