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 computer-design techniques have been used for the neodymium magnet system geometry to reduce intermodulation and harmonic distortion 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 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!

"Sennheiser HD 650 Audiophile Headphones WOW!!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I have several headphones including Sennheisers. I decided to treat myself and picked up a set of HD 650s from zZounds. After they arrived with free 2-day shipping, I plugged them in, threw on some live Volbeat and I was completely blown away!!!! The sound is beautiful, it sounds just like you are sitting dead center in the front row. Voice, guitars, bass, and drums are separated and sound perfectly crisp. Highs, mids, and bass all sound perfect with absolute zero distortion. Bass is so punchy and real, not faked which makes the boogie factor of a song make your butt do a little dance. You can't help it. There are no cons and well worth the money. Plus zZounds lets you make payments! You can't go wrong.
Musical Background:
Zero music ability, just absolutely love music
Musical Style:
Hard rock/metal and classic rock
