With scores of experience in the audio visual sector OPPO's latest offering for audiophiles, PM-1 headphones represent a new way of thinking about planar magnetic headphone technology. Defined by natural and engaging sound, OPPO PM-1 headphones are the result of many years of research led by a team comprised of passionate audio and acoustics engineers, chemical and materials scientists, and audiophiles.
Employing planar magnetic drivers set the PM-1 apart from the majority of headphones on the market. Sound is rendered by a very thin and light diaphragm whose entire surface area is evenly driven. The diaphragm is driven in a symmetric pull-push manner, and the magnetic system and conductor patterns have been optimized for maximum sensitivity and consistency.
OPPO PM-1 combines high sensitivity with low weight, allowing it to be used freely with portable devices without requiring additional amplification. Its circumaural, open back design provides the best in sound quality and comfort, and the overall rugged construction ensures that the headphones can withstand mechanical and environmental stress.
Larger than life sound.
When sound enters our ear, it has a planar wave front with all spectrum components in phase. A typical dynamic headphone driver disrupts this coherence with its phase irregularity, resulting in less than perfect signal peak reconstructions. OPPO’s planar magnetic driver has much better phase coherency since all parts of the diaphragm are vibrating in concert without break up and delayed resonance.
OPPO’s planar magnetic driver diaphragm has 7 layers of thin materials that provide excellent performance, reliability, and longevity. The construction of the diaphragm ensures that it is very stable under thermal stress and vibration. The diaphragm utilizes a spiralling pattern of flat aluminium conductors on either side of the driver. The double-sided design allows twice as many conductors to be placed within the magnetic field, which leads to higher sensitivity, better damping, and even drive force. An FEM-optimized magnet system with very high energy Neodymium magnets is used to maximize sensitivity and consistency of the applied force over the driver area.
The OPPO PM-1’s ear cushions are made out of the highest quality natural latex, which is superior and longer lasting to any chemically formulated foam. It is naturally hypoallergenic, retains its mechanical spring-like properties for much longer periods, and resists moisture build up from sweating. The headband and earpads are made of hand selected lambskin that provides a luxurious look and feel. OPPO PM-1 is ruggedly constructed with an emphasis on long term use and maximum consistency from unit to unit. The headphones have been tested to very high standards to withstand mechanical and environmental stress.
Easily Replaceable Components
The OPPO PM-1’s earpads are mounted on rubber inserts and can be easily cleaned or replaced. This design also makes switching between the leather and velour earpads nearly effortless. The headphone cable is detachable and uses non-proprietary, 2.5 mm mono mini jacks to connect to the earcups, making it easy to switch between the longer, 6.35 mm terminated cable for home use, and a shorter, 3.5 mm terminated cable for portable use.
The 6.35 mm terminated headphone cable features Ohno Continuous Casting (OCC) construction wrapped in a black fabric sleeve. The selvedge denim carrying case transports and protects the headphones in style, and the alternative set of velour pads provides a slightly different sound signature.
“The PM-1 can rightly be described as the most exciting new headphones to have been released this year.”
“The PM-1s are a resounding success. We love them, and we think everybody should hear them.”
“The Oppo PM-1 headphones are brilliant, mesmerising and spellbinding.”
“The stylish PM-1 offer a staggering combination of warmth, dimension, clarity, and definition that will utterly satisfy your audiophile fix.“
