HiFiMan Sundara Planar Dynamic Driver Over Ear Headphones The HiFiMan Sundara headphones are a pair of over ear headphones with planar dynamic drivers
What is a Planar Dynamic Driver
Sometimes referred to as orthodynamic headphones planar magnetic headphones differ to the more traditional dynamic headphone
Dynamic headphones generate sound by using a coil of wire (often called a voice coil) attached to a diaphragm and a suspension is created to allow the coil and diaphragm to move back and forth like a piston moving enough air to produce sound
However depending on the quality of the dynamic headphone speaker cone there will be inconsistencies across the frequency spectrum meaning that though many dynamic headphones have a very nice sound signature they are not necessarily 100% accurate when they reproduce an audio signal
Dynamic headphones also deteriorate quicker over time
In contrast planar magnetic headphones use an incredibly thin lightweight and resilient film diaphragm (around 1
10th the thickness of a human hair) stretched over a sturdy frame and placed between magnetic arrays
In these headphones the coil is unwound and spread across this film diaphragm
As the current flows the magnetic field is created within the headphone that causes the diaphragm to move
