The PM-50 takes full advantage of Planar Magnetic benefits to provide a balanced presentation across the musical spectrum. The combination of the open-back design, and Planar Magnetic technology results in reproduction devoid of the resonances and coloration inherent in common closed-back dynamic driver headphones. The inherent wide-range capability of Planar Magnetic technology results in a coherent audio singularity that totally eliminates the inevitable phase distortions caused by the crossover networks of multi-driver headphones. The result is an open, natural sound that is as true to the original performance as possible.
"The PM-50s pack a lot of value, with great comfort, precision build quality, and superb sound for their reference-grade magnetic drivers."
- Bob Hazelwood (Andover Chief Engineer)
