Building
full-size equipment capable of properly reproducing Sony's new media is
difficult enough. Add the constraints inherent in headphone design, and you'll
understand the design challenge of the MDR-CD7 headphones. To be effective with
the ES Series' digital-quality sound sources, they had to combine wide, linear
response, deep bass output, and full dynamic range. On top of all that, they
had to be lightweight and comfortable to wear.
Only the
Size and Weight are Small.
The
solution? An innovative transducer
design. The MDR-CD7 uses a small but very strong Samarium Cobalt magnet for
startlingly wide frequency-response. And a high compliance 24K gold ion plated
diaphragm exhibits extraordinary amplitude, resulting in an impressive dynamic
range of 135 dB.
For comfort,
the slightly off-center mounting position of the urethane earpads guarantees
proper side pressure distribution and good balance for all wearers. The pads
themselves are specially designed to conform to the ear, further increasing
comfort, providing 30 dB of isolation from ambient sound and extending bass
response.
Paying
Careful Attention to Detail
The cord is
made of nearly pure copper. More copper means less oxygen content - since
oxygen interferes with the transmission of the sound-carrying electrons, that
means the MDR-CD7's wire provides clear, open sound.
With a
conventional system, all this careful construction and expensive material might
seem like overkill. But with Sony's new digital-quality media, even little
things make a big difference.
That's why
the MDR-CD7 headphones sound so sensational.
