Leveraging nearly 100 years of combined audio expertise, German audio companies Sennheiser and Fischer Amps have teamed up to create custom in-ear monitors that deliver uncompromising sonic accuracy, fit and performance. The FA 500 Custom in-ear monitor combines the sonic perfection of Sennheiser's TrueResponse® transducer technology with Fischer Amps' precise, custom-fit enclosures that provide the level of comfort and isolation that professional artists and sound engineers demand.
The single wideband transducer, which is only 7 millimeter in size, covers the entire frequency range. Phase incoherency - which can be experienced with multi-driver systems - no longer exists. This technology enables sound reproduction with near-zero distortion even at maximum sound pressure; achieving up to a 100 times lower harmonic distortion than balanced armature drivers. This enables a sound reproduction that allows hearing in the finest nuances.
Watch this quick video for a detailed explanation on how the TrueResponse® transducer technology works.
As noted, in multi-way systems, crossover in individual frequency ranges of the sound source for bass, midrange and treble frequencies may lead to phase coherence problems and thus to a compromised sound quality. In addition, balanced armature drivers can have a significantly higher degree of distortion than a dynamic driver. Here is a visual example as measured through a GRAS RA402 Ear Simulator.
Because the FA 500 Custom in-ears are based on the anatomical shape of your ear and the auditory canals, they are extremely comfortable and provide a complete seal throughout your entire performance. They are uniquely tailored to your ear shape and therefore provide perfect sound isolation from ambient noise. They come in 10 customizable colors.
