Avantone Pro Planar is the original open-back planar-magnetic headphone with 70 x 95 mm drivers for reference monitoring. This black finish listing is the first-generation Planar, not Planar the II. Front-and-rear magnet arrays and an open-back chamber aim for low distortion, wide bandwidth, and long-session comfort.

Planar Reference Monitoring

N50SH magnets and a 21 micron PET diaphragm drive the 70 x 95 mm planar transducers. Specs include 30 Hz - 30 kHz response, 32 Ω impedance, 104 dB/1 mW sensitivity, THD below 0.1% at 100 dB, and up to 5 W RMS. Minimum power is >100 mW; >250 mW is recommended. A removable 3.5 mm cable plugs into either side.
