The best of two brands combined in one custom in-ear monitor:
Sennheiser x Fischer Amps FA 500 Custom
Motivated by and together with our customers, the FA 500 Custom in-ear monitors were born, mating 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.
