This is the B1-E dummy head with the BE-P1 microphones installed in the ear canals of silicone ears. It is a fully operational binaural recording device ready to use and capture deeply immersive sound which will never cease to give the listener an impression of being in the same place where the microphone was.
This design uses two condenser microphone capsules with a sensitivity of -28dB, what along with very low self-noise, makes them ideal for recording quiet sounds. It can be succesfully used for recording sound effects, ambient sounds, podcasts, instruments, and ASMR videos.
The BE-P1 microphone module has its own battery box, which helps it perform even better especially when recording louder sound sources such as live concerts. Battery box can also be very helpful in case when your recorder doesn’t provide enough plug-in-power.
The microphones are powered directly from a battery box. Thanks to this solution, the microphone can be used with cameras, computers or any other recording devices equipped with a 3.5mm female connector.
The battery box has an optional low-cut filter built in. This filter allows you to cut off or attenuate the low frequencies. In some circumstances this feature can be helpful in improving the quality of your recording; for instance, by removing unwanted noises (i.e. air conditioners and traffic) or attenuating excessively loud low frequency sounds, such as a kick drum.
The cutoff frequency is set at 180 Hz with a slope of 6dB per octave.

Realistic earlobes are one of the most important components of a true binaural microphone. Every effort was made to create silicone ear models that would imitate as closely as possible the natural anatomy of the human earlobes. The silicone ears are made of high-tensile strength and skin safe silicone rubber. The ears are flexible and feel almost like natural human skin. They were cast from a mold based on real human ears.
The dummy head is made of fiberglass. The size and shape are similar to a natural human head, which provides proper ear spacing. Additionally, the interior of the head is filled with sound-absorbing foam. Thanks to the female 1/4 x 20 thread at the bottom, the microphone can be easily mounted on a tripod. The whole dummy head microphone weights approximately 2-2,5kg (4.5-5.5 lbs)
The most original aspect of this device is that it is equipped with two removable ball heads (both with a 1/4 x20 thread), which allow you to mount a recording device as well as a small camera.
The Binaural Enthusiast microphone, due to such features as the realistic dummy head shape, silicone earlobes and hyper-sensitive microphones, allows you to record a unique 3D audio effect that will sound almost identical to what is heard by a human. The video from the camera, mounted on one of the available attachments, will only deepen the realism and quality of the recorded material.
Please note that the ears as well as the head can have some imperfections, such as very small holes from air bubbles, or very fine scratches. This does not affect the function or the quality of the recorded sound.
The camera and the audio recorder are not included.
