planar magnetic iems
Impactful, unique sonic performance
Advanced performance
Until recently, planar drivers were deemed unsuited for IEM applications; held back by size, sensitivity and cost limitations, they were long used in over-ear headphones. However, advancements in this technology have overcome these limitations enough for them to be used in portable, in-ear applications.
Now, the wonderful character and advantages of planar drivers can be brought to IEM lovers; with their unique blend of size and speed and accompanying unique sonic characteristics.
Campfire's first planar IEM, Supermoon's premium, planar sound quickly became a fan favorite and became one of the most renowned planar IEMs on the market. Now, Campfire Audio is an industry leader in planar application and engineering.
Planar mechanics
Planar drivers present a unique blend of size and speed, where other driver types typically require a trade-off in one of these areas. This enables planar drivers to make rich, powerful, sonic impact, while also maintaining rapid response, accuracy and detail.
These unique properties give planar drivers their characteristic timbre and tonality.
planar advantage
Planar driver’s serpentine voice coil is distributed evenly over the surface of the diaphragm which stimulates driver movement such that the driver does not warp or bend as it moves back and forth.
This contributes to the drivers incredible accuracy and rapid impulse response, making each note tight and defined and avoiding smearing seen in other large, dynamic drivers.Â
Another unique facet of planar performance is its propagation of a plane wavefront, contrasting with the spherical wavefront created by standard cone speakers/dynamic drivers.
The shape of a given wavefront will change the acoustic interaction with the ear canal, changing reflections and altering our perception.
Another advantage of planar technology is the incredibly low overall THD ratio.
Combined with speed, precision, and even movement of the planar driver, this super low THD ratio adds another layer to the planar driver’s crisp, clean, and accurate sonic reproduction.
