Sennheiser and Fischer Amps have collaborated on the FA 500 Custom, a professional in-ear headphone that combines Fischer Amps' handcrafted custom earpieces with the dynamic transducer of Sennheiser's IE 500 PRO model. Equipped with Sennheiser's TrueResponse technology, these in-ears open up a natural, clear and spacious soundstage, allowing musicians and engineers to control their sound with complete focus.
A single sound source directly at the ear, offers the greatest potential for a natural, punchy and highly nuanced sound experience compared to multi-way systems found in many loudspeakers and traditional IEM systems with multiple Balanced Armature drivers.
In multi-way systems, different frequency ranges of the sound sources for bass, midrange and treble frequencies at their transition lead to phase coherence problems and thus to a distorted sound image. In addition, balanced armature drivers have a significantly higher degree of distortion than a dynamic driver.
With the dynamic TrueResponse driver system, Sennheiser offers the technology to solve this problem - a broadband driver that covers the entire spectrum, enabling maximum dynamics with the lowest distortion factor. At the heart of any in-ear monitor design is the smallest element - the transducer - that makes the biggest difference, especially in the small, confined space of the ear.
The 7 millimetre wideband transducer covers the entire frequency spectrum from 6 Hz to 20 kHz. This eliminates the phase differences that occur in multi-way driver systems. Only this technology enables truly distortion-free sound reproduction even at maximum sound pressure levels, achieving up to 100 times less harmonic distortion than balanced-armature drivers. The sound signature of the FA 500 Custom thus enables musical reproduction in the finest nuances.
The FA 500 Custom are custom in-ear headphones based on the anatomical shape of the pinna and ear canal. They are made solely based on your ear impression and therefore provide the perfect sound isolation for ambient noise and excellent listening comfort, ensuring a stable but comfortable wearing experience even over long periods of time.
Whether you prefer a more discreet and unobtrusive style or a more striking and distinctive one; design your FA 500 Custom according to your own wishes with a range of colour finishes, at no extra cost. Even unusual wishes and designs (e.g. your band logo) can be realised.
Please refer to the manual icon above, which will direct you to the FA 500 Custom order form. Since these are custom in-ear headphones based on the anatomical shape of the pinna and ear canal, and the FA 500 Custom are designed to your own specifications, some information is required for a complete order tailored to your listening experience
