PM-50 Planar Headphones
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-50 Headphones are driven by any source including smartphones, portable music players, DACs, traditional audio systems, and dedicated headphone amplifiers.

Superb Audio Performance
The PM-50 drivers reproduce music with studio-grade authenticity. Expect a large, clearly defined soundstage, rich musical detail, and a natural balance between instruments and vocals.

Planar Magnetic Technology
Andover's PM-50 drivers are made with the same processes and knowhow that create the Air Motion Ribbon Tweeters used in the Model One Turntable Music System. 
Typical dynamic drivers are susceptible to "cone breakup", a characteristic distortion resulting from diaphragm flex that reduces sonic accuracy. Andover's 50mm Planar Magnetic drivers instead distribute the driving force across the entire surface of the diaphragm, eliminating this issue.

Precision Crafted
Following the industrial design from Andover's Model One Turntable Music System, the PM-50s feature finely crafted housings of genuine walnut, which provide a solid acoustic enclosure for the Planar drivers.

The PM-50's open-back acoustic design provides transparency and spatiality that is uncommon in conventional closed-back headphones.

The Perfect Fit and Comfort
The PM-50 Headphones uniquely offer two sets of ear cushions, giving listeners two options for their favorite sound and comfort.

The ergonomic headband, designed for comfort and lightweight, is continuously adjustable  for the perfect, all-day fit.
