Sonorous Objects In-Ear Stereo Microphones PREORDER SALE

Sonorous Objects In-Ear Microphones provide highly immersive 3D sound in a small discreet form factor. These microphones are provided as a matched stereo pair and sit just outside of your ears - just as you wear earbuds and AirPods. In this format, the microphones are located close to your ear, the sound captured is richly realistic and similar to how we hear. These in-ear mics also allow a level of inconspicuity that traditional microphones do not due to the ubiquity of the in-ear headphones. Offered in EM272 and EM258 variants, our in-ear mics have the same highly sensitive, low noise, and detailed nuanced sound as our other microphones. Our in-ear mics, together with the array on either side of your head, provide a breathtakingly realistic spatial image and deep soundstage. The SO In-Ear Microphones utilize Primo's highly regarded EM272 / EM258 capsule, favorites among field recordists, sound designers, location sound, and artists working with sound. The Microphone design allows for the addition of foam windscreens (included), or furry windscreens to aid in reducing wind noise. The microphones are housed in a plastic enclosure produced and fabricated here in NYC. We use high quality Mogami shielded cable that terminates in a Neutrik Gold Right Angle 3.5mm plug.
