Sennheiser HD 800
3.8Overall Score
Price (RRP): $2,399 Manufacturer: Sennheiser

A few years ago now, as a lowly hi-fi sales assistant in London’s Covent Garden, I can lay claim to having sold a pair of Sennheiser’s most expensive headphones. The Orpheus was a gorgeous reference electrostatic headphone driven by its own high-end valve amplifier and the American customer who bought the pair from me was lightened of some £10,000. At today’s exchange rate, that’s around AU$22,000.

Sennheiser recently launched its latest flagship pair of ‘cans, the HD 800, which at $2399 a set have a much more palatable price tag. Let’s face it, though, it’s still a lot of cash.

Top-end Sennheisers are usually something to get excited about, and owning a pair of HD 600s myself I was keen to learn just how much better, if at all, the step-up 800s were.

Features

Handmade in the factory in Germany – like all Sennheiser designs – the HD 800s are an open-backed circumaural design, meaning there’s some outward sound leakage. Sennheiser says the patented 56mm transducer (the part that converts the electrical signal into sound) is the largest ever incorporated in a pair of headphones. Transducers with a large surface area are better at generating full bodied sound and solid bass levels, but typically also generate distortion. Sennheiser claims to have overcome this by developing a ring-shaped transducer. While this actually has less surface area than a conventional circular transducer of the same dimension, it manages to vibrate the same volume of air above it, according to Sennheiser.

The doughnut-shaped drivers are angled from inside the ear cups at 45 degrees to the ear canal. This emulates the way sound arrives at our ears from a pair of triangulated stereo speakers, making the listening experience more natural.

Solid and mostly metallic in construction, the HD 800s are still very comfortable thanks to luxurious touches such as ear pads made of a Japanese man-made fibre called Alcantara, which is also used as a high-quality interior fabric in the automotive industry. The three-metre cord doesn’t get in the way either, and is constructed from four-core Teflon insulated cable.

Performance

First up, know that these cans are not intended for use for portable players such as iPods. These devices won’t drive headphones like the HD 800s because they simply can’t handle the high impedance (ie. electrical resistance) presented to them. I ran the HD 800s straight off a dedicated valve output from a Shanling Super Audio CD player as well as via a $1,549 Lehmann Black Cube Linear headphone amplifier, which was supplied by Sennheiser’s Aussie distributor, Syntec.
