Designed as the first true full-isolation interruptible foldback (IFB) earphones for broadcasting and teleprompting, the ProPhonic 321™ provides outstanding performance for both crew and on-air talent. Unlike traditional IFB earphones, the custom-molded ProPhonic 321 places a micro-transducer directly within the ear canal, providing 26 dB of isolation from external sounds so that the critical earphones communications can be heard and understood in even the noisiest environments without – raising the volume.
Cosmetically, the miniature design of the ProPhonic 321 completely disappears into the ear, connecting to the IFB monitor system via a near-invisible Teflon-coated wire connected directly to the earphones. Because its soft gel silicone material is custom-molded by a Sensaphonics audiologist, the ProPhonic 321 is incredibly comfortable, even during prolonged use. Sound quality is clean and clear, designed for high intelligibility and low-distortion.
The ProPhonic 321 is available in binaural (dual earphones) and monaural (single ear) designs.
