Sennheiser HD 565 Ovation Headphones Review
Sennheiser manufactures a comprehensive line of headphones and microphones, ranging from inexpensive consumer products to the finest professional components. One of the company's latest consumer stereo headphones is the HD565 Ovation, a high-quality design that boasts a number of advanced features.
There are two major classes of headphones: those whose transducers are in sealed earcups that exclude ambient sound from the wearer's ears, and the open-air variety, whose transducer diaphragms radiate sound from the backs of the earcups as well as into the wearer's ears. Open-air phones are usually lighter and more comfortable to wear and are widely used for home hi-fi listening.
Although the HD565 is of the open-air type, it looks somewhat bulky, with large earcups that fully enclose the ears. Instead of the usual rubber or plastic ear cushions, the HD565's cushions are made of a velvet-like cloth, and its spring-type headband is padded with a foam strip.
Unlike most other headphones we have used, the HD565 is designed for easy user replacement of all parts that are likely to wear out or could be damaged in normal use. These include the 3-meter (about 10-foot) connecting cord and phone-plug assembly, which is fitted with polarized connectors, and the ear cushions, whose plastic rims snap into the earcups.
The warranty booklet supplied with the phones also contains informative material (in five languages) on the meaning of the various applicable specifications and on the significance of the phones' design features. The specs are based on the German DIN 45500 standard, however, and are not easily interpreted in terms familiar here. The frequency response is given as 16 Hz to 30 kHz, and the distortion as less than 0.15 percent, without further elaboration.
The HD565 is an exceptionally comfortable headset to wear. The earpieces cover the ears without imparting a sense of pressure. And despite their massive appearance, they are light in weight and essentially transparent to sound. The slender connecting cable is light and unobtrusive.
