3DIO Free Space Binaural Microphone | The 3D Dummy Head Microphone Born for ASMR and Immersive Recording
Simulating Human Hearing to Capture the Most Authentic Spatial and Directional Sense
The 3DIO Free Space is a professional-grade binaural dummy head microphone launched by 3DIO Sound. It features a pair of high-sensitivity electret condenser microphone capsules integrated into realistic human ear models, capable of capturing sounds within a frequency response range of 60 Hz to 20 kHz. It is one of the world's most popular solutions for ASMR recording, VR virtual reality, and Field Recording, specifically designed to capture immersive 3D audio.
Compared to traditional stereo microphones that only record left and right channels, the 3DIO Free Space simulates the physical changes of sound waves as they interact with the human ear structure (Pinna). This achieves an immersive 3D audio experience that accurately reproduces the sound source's location and spatial depth. When listeners use headphones to listen to recordings made with it, they experience a lifelike auditory sensation, as if they were present at the recording site.

3DIO Free Space Core Technologies and Features
- Realistic Binaural Design:Perfectly simulates the shape, density, and spacing of human ears. The built-in microphone capsules capture subtle changes in sound waves after reflection and diffraction by the pinna, accurately reproducing the sound's directionality, distance, and spatial sense.
- High-Sensitivity Capsules: Utilizes a pair of factory-matched electret condenser microphone capsules with a high sensitivity of -28 dB and an 80 dB signal-to-noise ratio, capable of clearly capturing the faintest sound details, from whispers to ambient atmospheres.
- Warm and Natural Tone: The capsules feature a natural roll-off in frequency response above 10 kHz, effectively avoiding harsh high frequencies. This makes it particularly suitable for recording high-frequency rich instruments like drum cymbals or acoustic guitar strumming, while also providing a warm and full mid-low frequency response.
- Independent Power from Built-in Battery: Powered by a single 9V battery, it offers over 300 hours of battery life. No external phantom power is required, allowing direct connection to DSLR cameras, portable recorders, or computer 3.5mm microphone input jacks, ensuring high portability.
- Low-Frequency Roll-off Filter: The unit is equipped with a 160 Hz Bass Roll-off switch, which effectively filters out low-frequency environmental noise such as air conditioner hum or wind noise, ensuring clarity of vocals and key sound sources.
- Standardized Mounting Interface: The bottom features a detachable 5/8" microphone stand adapter. When removed, it reveals a 1/4"-20 standard threaded hole, allowing easy mounting on most camera tripods, hot shoe adapters, or handheld grips available on the market.

3DIO Free Space Frequently Asked Questions FAQ
Q: How do I connect the 3DIO Free Space Binaural Microphone to my computer or camera?
A: You can directly plug the 3.5mm cable into your computer's or camera's microphone input jack. Since it provides a mic-level output, it's recommended to use an audio interface with a preamplifier for optimal sound quality.
Q: What are the differences between the 3DIO Free Space and Free Space XLR versions?
A: The main difference lies in the output. The Free Space features a 3.5mm unbalanced output powered by a 9V battery, while the XLR version offers dual XLR balanced outputs and requires 48V phantom power.
Q: I'm new to ASMR, is the 3DIO Free Space suitable for me?
A: Absolutely. The Free Space is one of the world's most popular ASMR microphones. It's intuitive to operate, requires no complex setup, and allows you to easily record professional-grade 3D audio with immersive and spatial qualities.
Q: Do I need to turn on the power switch of the 3DIO Free Space when recording?
A: Yes, when using the 3.5mm output, the power switch must be turned on to activate the built-in 9V battery, which powers the microphone capsules. Turning off the switch when not in use saves power.
