The best of two brands combined in one custom in-ear monitor.
The FA 500 Custom in-ear monitors combine Sennheiser's TrueResponse® technology with Fischer Amps' custom-made housings. Comfort and perfect fit meet reliable sound purity.
In-ear monitoring starts with the right transducer technology
A single unimpeded sound source coupled directly to the ear offers the greatest potential for the most natural, powerful, and highly nuanced audio experience, as compared to multi-way systems found in many loudspeakers and conventional IEM systems with balanced armature drivers.
In multi-way systems, crossover in individual frequency ranges of the sound source for bass, midrange and treble frequencies leads to phase coherence problems and thus to a compromised sound quality. In addition, balanced armature drivers have a significantly higher degree of distortion than a dynamic driver.
To solve this problem Sennheiser engineered the key component called the TrueResponse® technology, made of a precision-crafted broadband transducer that covers the entire spectrum, enabling maximum dynamics with the lowest distortion factor.
For us, 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.
Ultra-lightweight, customized acrylic housing and ear mold design for perfect, secure fit and consistently high sound isolation, with excellent wearing comfort and steady sound
True phase linearity due to the single 7 mm TrueResponse® transducer covering the entire frequency range
Virtually distortion-free with only < 0,08 % total harmonic distortion
Reliable audio reproduction even at maximum SPL
Replaceable, twisted-pair connection cable with excellent structure-borne noise resistance, rotatable shock-proof plug connection
Uncompromised sonic accuracy by Sennheiser TrueResponse® technology
The single wideband transducer, which is only 7 millimeter in size, covers the entire frequency range. Phase incoherency - occurring with multi-way driver systems - no longer exists. Only 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.
The sound signature of the FA 500 Custom enables a sound reproduction which allows hearing in the finest nuances.
Unique fit – yours
The FA 500 Custom are customized in-ear monitors based on the anatomical shape of your ear and the auditory canals. They are uniquely tailored to your ear shape and therefore provide perfect sound isolation from ambient noise, thus a far superior listening comfort and a stable but pleasant wearing experience during the entire performance.
Individual style desired?
No matter whether rather discreet and inconspicuous or unusual and eye-catching, customize your FA 500 Custom according to your own wishes with a range of color finishing, at no extra costs. Even special wishes and designs (e. g your band logo) can be realized. For this, simply contact Fischer Amps. We will be pleased to give you guidance.

In-ear monitors have become a standard addition to every musician or sound engineer serious about their job, no matter whether you’re headlining the main stage or starting off your path. The essentially small monitors, got into your ear, blocking outside noise and give you the direct mix while on stage, at rehearsal or in the studio. Decisions on universal vs. custom fit, color or cable routing are typically based on individual preferences. More difficult is the choice of the audio technology. When it comes to your audio experience, don’t settle for any trade-offs.
Once you try in-ear monitors with Sennheiser’s proprietary TrueResponse® technology, you’ll never want to use a different set of IEMs again.
