DPA 4560 CORE+ Binaural Headset, Normal SPL, MicroLock (4560-OP-B-B90)

DPA 4560 CORE+ Binaural Headset Mic (Black)

The DPA 4560 CORE+ Binaural Headset Microphone is, in its essence, a pair of 4060 CORE+ Miniature Omnidirectional Microphones that are mounted on two earhooks (as known from the 4266 Flex type of headset). The microphones are a stereo pair; two handpicked 4060s, selected on sensitivity within ±1.5 dB. The actual headset is ergonomically designed to fit comfortably and easily. It adjusts to fit any ear size and head shape while at the same time it mounts securely and is hardly visible. Foam windscreens are supplied with the microphones to secure the position in the ear and to offer some damping of wind noise.

The 4060 CORE+ Miniature Omnidirectional Microphones in this headset exhibit an exceptionally accurate omnidirectional pattern and therefore do not need to be aimed directly at the sound source to achieve quality pickup. This pattern also makes it less sensitive to handling noise as well as pop and wind noise. These 4060s handle sound pressure levels up to 134 dB before clipping occurs. This headset mic is well suited for applications where the sound source is more remote or damped and you need to have a good balance signal versus noise.

Binaural recording is a technique that uses two microphones to create an immersive 3D stereo sound experience for the listener. When correctly accomplished, these recordings allow the listener to hear sounds like they are actually in the same position as the person who did the actual recording. Binaural recordings differ from more well-known stereo techniques because binaural uses two omnidirectional mics positioned close together (as if in a listeners ears) to replicate the sound pick up of the human ear as close as possible. Stereo on the other hand, use cardioid microphones with a larger space between them.
