According to the manufacturer, Planar Open-Back Headphones is the culmination of Avantone Pro’s experience in creating reference-grade monitoring products to meet the demands of modern-day professional end-users by putting Planar drivers in the driving seat for extreme detail, and supreme comfort for long sessions, surely an ideal solution for mix engineers, musicians, podcasters, live-streamers, and hi-fi enthusiasts alike as audiophile sound meets portability.

Amazing accuracy, high-end detail, clarity, natural bass, and response time are just some of the advantages that Planar drivers offer over traditional moving coil drivers. After all, traditional moving coil drivers use a magnetic field to push/pull the driver in one direction and really rely on the surround’s elasticity to return the driver to the neutral position.
Planar drivers utilize a technology that mixes principles between dynamic and electrostatic drivers since they are constructed from a precise array of magnets that are evenly spaced across both sides of a thin, electrically-active diaphragm. Due to the nature of this magnetic field’s precision, force applied to the membrane is distributed in a symmetric fashion that produces a signal with very little harmonic distortion and incredibly fast response times. There is also far less weight applied to the driver material since planar drivers use front- and rear-mounted magnets, Neodymium N50SH, in the case of Avantone Pro’s Planar — to apply equal forces in both directions, resulting in a much more natural sound with less distortion, and allowing for hours of fatigue-less listening.
The Planar headphones from Avantone Pro have an open-back design with an optimized chamber, which provides a very flat-frequency environment without disturbing typical pressure build-up. The Planar is slightly larger than typical headphones, but that doesn’t affect comfort in any way. The soft and spacious ear pads offer additional comfort.

The Planar covers a wide frequency range from 30 Hz to 30 kHz, while the low impedance (32 Ω) enables better use with audio interfaces, hi-fi systems, or mobile devices. It comes with a high-quality 3.5mm cable that can be connected to either side of the headphones and comes in an environmentally friendly shoulder bag with room for accessories.
