Frequently Asked Questions
Custom IEMs offer a personalized fit and often improved isolation and sound quality compared to universal models, but require a professional fitting process.
While the bass is emphasized, it's controlled and detailed; however, listeners preferring a completely neutral signature may find it slightly colored.
Fischer Amps provides a range of faceplate designs, allowing for personalization of the IEM’s aesthetics beyond the transparent housing.
