Large 16 Mm Dynamic Driver Unit - Sony MDR-NC300D Product Information

3-3 Large 16 mm Dynamic Driver Unit
A large 16 mm dynamic driver unit is used as the closed ear receiver.
In addition to the improved canceling of loud/ultra-low frequency environmental
noise, this makes the most of the merits of wideband regeneration and the broad
dynamic range to produce clear, natural sounds with a wide, balanced frequency range.
Integrated Structure of Driver Unit
For the sake of miniaturization, the driver unit has been integrated with the casing. As well as eliminating unwanted air leakage
from the gaps between components, this has reduced unwanted vibration and attained a smooth response in the low range.
