On ear headband headphones
Fidelio Black
Acoustic seal
The acoustic seal is a specially designed ribbon
lock that's built into the internal chamber to
eliminate any unnecessary sound leakage and
preserve sound details. The result is excellent
bass extension.
Bass Reflex System (BRS)
The acoustic closed-back architecture features
a Bass Reflex System that comprises ear-shells
with strategically placed vents. These regulate
the air pressure within the internal chamber
providing the diaphragm with a controlled
environment for optimal acoustic response.
Working in conjunction with the acoustic seal
capture, it isolates every natural sound detail
and delivers precise and dynamic bass without
compromising on sound clarity.
Double-layered ear-shells
The M1i's double-layered ear-shells are
engineered to reduce resonance and to
dampen vibration for genuinely precise and
clean sound so you hear every superb sound
detail. The solid, layered construction ensures
durability and comfort, making the M1i an ideal
music companion for a long time to come.
High definition speakers
Each speaker driver is carefully hand picked,
tuned and tested before being paired to ensure
the most balanced natural sound. The 40mm
drivers utilize high power neodymium magnets
to deliver true high definition sound in a wide
dynamic range, reproducing even the most
minute details.
Tuned frequency response
Extensive research was done with discerning
music-lovers to gain insight to their listening
preferences - for example, the balance of
sound characteristics that they favored. Our
acoustics engineers then tuned the Fidelio M1i
to account for all the minute details that affect
how listeners discern sound, such as how the
ear reflects sound and resonates in response.
As a result, our M1i headphones are
engineered to reproduce sound that is as
faithful to the original recording as possible -
including current recording styles.
Deluxe breathable ear pads
The materials used for the Fidelio M1i are
carefully selected to ensure long-wearing
comfort and enhanced sound performance.
Deluxe breathable ear pads with memory foam
are designed for optimal ergonomic fit. Not
only does the foam mould itself perfectly to the
shape of your ear, it also seals in bass sounds
while keeping out ambient noise. This is
designed with the outer cushion - using a
balanced proportion of fabric and protein
leather - to reduce ear surface pressure and
heat build-up, so that the M1i feels and sounds
excellent.
