Perfect in every detail.
The experience Sennheiser gained in designing the legendary Orpheus headphones has been
incorporated into the HD 650. They are superbly well balanced with crisp bass, excellent mid frequency response and a gentle,
pleasantly natural treble. The HD 650 are the first dynamic headphones with such authentic and natural sound reproduction,
both accurate and transparent.
The technology is innovative, and the workmanship immaculate. A specially developed acoustic silk ensures uniform precision
damping over the entire frequency range and reduces harmonic distortion to an incredible 0.05%. The headphones are fitted
with hand-selected, close-tolerance systems and the latest computer-design techniques have been used for the neodymium
magnet system geometry to reduce intermodulation and harmonic distorion to a previously unattainable level.
The extremely lightweight aluminum voice coils ensure an extremely fast transient response; while neodymium iron magnets
ensure maximum efficiency. The diaphragm was designed using the latest simulation technology. The design has a refined
titanium-silver finish and the ear-pieces feature 62% open metal mesh covers. The high-quality oxygen-free copper (OFC) cable
was specially developed for the HD 650. It is extremely resilient thanks to its Kevlar fiber reinforcement, creating the perfect
link with minimum sensitivity to handling noise.
Words are one thing – experience is another. The HD 650’s really have to be heard to be fully appreciated.
So take your most demanding recordings to your nearest Sennheiser dealer and hear the music as it really is.
New high-quality Kevlar-strengthened
OFC cable, matched to the headphones.
2-point headband pad, to ensure hours of absolute music comfort.
No pressure on the sensitive middle portion of the head.
