RecMic II SeriesThe power to deliver exceptional accuracy and EHR/PACS integration Create clean, accurate verbal notes efficiently with the Olympus RecMic II. This series of desktop dictation microphones combines advanced technologies in an innovative noise canceling system ideal for noisy environments. Intelligent dual microphones control the directionality to keep the focus on the person dictating, and suppress non-voice noise eliminating anything outside the human frequency range.  In addition, a triple-layer studio-quality filter blocks traditionally problematic sounds including breath noise. The RecMic II microphones retain accurate spoken audio without any distortion while suppressing unwanted noise, and make desktop dictation easy.


Capture Your Voice Without Unwanted Noise The power to deliver exceptional accuracy and EHR/PACS integration.

Noise Cancellation technology for optimum speech recognition results. The combination of dual microphones and the innovative noise cancelling technology revolutionizes speech recognition accuracy when dictating – even in extremely noisy environments. The next generation of the RecMic Series provides the most advanced USB microphone and therefore fulfills even the highest user demands.

Command Quickly and Quietly. No need to remember verbal commands. Intuitively positioned controls and superb ergonomics enable lightning-fast dictation and free you from unnecessary finger movements. Studio quality technology –and quiet construction also blocks unwanted but difficult-to-eliminate sounds such as breath and wind vibrations with a triple-layer pop filter, cushions “click-less” buttons, and a smooth surface coating.

Antimicrobial – ergonomic – robust: perfect for daily clinic life. An antimicrobial surface supports hygienic requirements. This is why the RecMic II models are especially suitable for everyday clinic routines. The ergonomic shape and the extraordinary robustness of the products also meet the demands of the market.



Accurate & Clear Speech Recognition in a Noisy Environment

Dual microphone technology creates narrow directionality that focuses on the acoustics in front of the microphone and suppresses unwanted noise from the sides and back.

Professional Studio-Quality Filtering

The triple-layer pop filter uses the same technology found in professional studio recording microphones to block unwanted but difficult-to-eliminate sounds such as breath and wind vibrations.

Antimicrobial Body

The housing and buttons on every RecMic II are made of antimicrobial coating materials (ISO 22196). The “tolerance to alcohol” design allows for superior cleanability.

Intuitive Configuration

The RecMic II is easily configurable with third party applications including web applications without having Olympus software running, and can be used as a USB Keyboard for easy control simply by changing modes.

    Works really well

    Posted by Marian Gilmore on Apr 24th 2023

    I was immediately impressed with its noise-canceling feature, which eliminates background noise and ensures that the sound quality is crystal clear. The slide switch is also incredibly easy to use, allowing me to control the recording process with just one hand. It's made a huge difference in my work and has saved me a lot of time and frustration in the transcription process.

    This is a very nice product, I have been using the Olympus RecMic II for the past month now and it has never let me down. The noise canceling feature is great, it really helps cutting out background noise. I would recommend buying this product to anyone who is looking to use a desktop dictation system.
