Sennheiser HD 650 Overview

The HD 650 from Sennheiser are reference-class stereo headphones designed to deliver a true audiophile experience with an open, natural sound. Specially developed acoustic silk was used to provide uniform attenuation over the entire area of each ear-cup. The lightweight aluminum voice coils ensure a remarkable transient response, while the full-range drivers offer a frequency response of 10 Hz to 39.5 kHz. Great care was taken to ensure the headphones are comfortable with their elliptical design, which naturally adapts to the shape of the ear.

The HD 650 utilizes a 9.8' detachable cable made from a highly conductive OFC copper with low handling noise and low structure-borne sound sensitivity. The headphones can be used with high-output mobile devices and excel with high-quality stationary hi-fi components such as SACD, DVD-A, and CD players. The HD 650 ships with the detachable cable and a 1/4" to 3.5mm adapter.

  • Top-of-the-range open, dynamic hi-fi stereo headphones
  • Systems with narrow tolerances (±1 dB), hand-picked in pairs
  • High-quality titanium / silver finish
  • Specially developed acoustic silk for precise, uniform attenuation over the entire area
  • Specially modulated connecting cable (detachable) made from highly conductive OFC copper, with very-low handling noise
  • Extremely lightweight aluminum voice coils ensure excellent transient response
  • Comfortable to wear due to elliptical design adapted to the shape of the ears
  • Can be directly connected to stationary hi-fi components of the highest quality, in particular SACD, DVD-A, and CD players

Most PC sound cards will not drive these 300 Ohm headphones. Use a headphone amplifier.

Will they work with an iPhone or iPad?
Asked by: Lowell
The Sennheiser HD 650 Stereo Reference Headphones have a higher than average impedance rating of 300 ohms, so although they will work with any device that has a 3.5mm headphone jack, they may be quieter than expected when used with consumer devices such as phones and tablets. For that reason, using a separate headphone amplifier is recommended.
