OM SYSTEM ME-51S Directional Stereo Microphone for Digital Recorders and Cam

The OM SYSTEM ME-51S Directional Stereo Microphone is a compact external microphone built to deliver more focused, intelligible stereo audio for compatible digital recorders and select devices that accept a 3.5mm microphone input. Compared with an internal microphone, the ME-51S is designed to better isolate the sound source in front of the mic, making it a practical upgrade for lectures, interviews, meetings, presentations, vlogging, and general field recording.

Compatible With

• Olympus and OM SYSTEM digital voice recorders with a 3.5mm microphone input and plug-in power support, including many WS-, VN-, DM-, and LS-series models
• Select cameras, camcorders, and audio devices with a 3.5mm mic input that can accommodate an unpowered plug-in stereo microphone

Directional Stereo Pickup

The ME-51S combines the spaciousness of stereo recording with a directional pickup design that concentrates on the subject in front of the microphone. This makes it especially useful when you want to capture a speaker, performer, or sound source with greater clarity while minimizing surrounding distractions. It is a smart choice for classrooms, houses of worship, conference rooms, and event spaces where ambient noise can compete with the main subject.

Compact and Travel-Friendly Design

Small and lightweight, the microphone is easy to slip into a recorder pouch, camera bag, or jacket pocket. Its portable form factor makes it well suited to mobile content creators, journalists, students, and professionals who need an uncomplicated audio accessory that is ready to go at a moment's notice.

Simple 3.5mm Connectivity

The microphone uses a standard 3.5mm stereo mini plug for broad compatibility with supported recorders and other audio capture devices. This straightforward connection allows for fast setup with minimal technical knowledge required. Plug it in, position it toward the subject, and record with improved front-focused stereo sound.

Better Audio Than Built-In Microphones

Built-in microphones are convenient, but they often pick up handling noise, room ambience, and off-axis distractions. By moving the microphone away from the body of the device and using a more directional stereo pickup pattern, the ME-51S can help produce cleaner recordings with better subject definition. This can be especially helpful for spoken-word capture, note-taking, and documentary-style recording.

Ideal Uses

This microphone is well suited for recording lectures, interviews, meetings, musical performances, nature sounds, public speaking, and video projects that benefit from more focused stereo audio. Users of digital voice recorders will appreciate the improved clarity when transcribing speech, while camera users can benefit from more intentional sound capture than an onboard microphone typically provides.

How It Compares

Compared with a standard omnidirectional add-on microphone, the ME-51S is better suited for situations where the main sound source is clearly in front of the mic. Compared with a full-size shotgun microphone, it is more compact and easier to carry, though it is intended as a lightweight portable accessory rather than a large professional boom solution. For many everyday recording tasks, it offers a practical balance of portability, stereo imaging, and directional control.

Usage Tips

For best results, aim the microphone directly toward the subject and keep it as close as practical without entering the frame if used on camera. In echo-heavy rooms, reducing distance to the speaker can significantly improve intelligibility. If your device offers manual recording levels, set them conservatively to avoid clipping during louder passages. When recording outdoors, consider additional wind protection if conditions are breezy.

Recommended Accessories

Useful companion items include a compatible digital recorder, a camera or recorder with a 3.5mm microphone input, a small carrying pouch, a mic extension cable if supported by your setup, and wind protection for outdoor recording. A tabletop tripod or support can also help reduce handling noise during extended sessions.
