Leveraging nearly 100 years of combined audio expertise, German audio companies Fischer Amps and Sennheiser have teamed up to create custom in-ear monitors that deliver uncompromising fit, sonic accuracy, 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.
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.
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.
