Sennheiser’s making quite a bold claim here – the world’s best headphones. The HD800s apparently sound better than any other pair of headphones on the planet. I suspect that it might be difficult to prove that one to a jury – surely it’s more than a little subjective?

But let’s not quibble over that – it’s beyond doubt that these are damn good. A brand new “RING” driver, developed specifically for these cans alone, can deliver an amazing 6Hz – 51kHz frequency response. For comparison, your average person on the street can hear about 20Hz to 20kHz. Unless you’re an audiophile, therefore, you’re not going to get much out of these. Sennheiser also claims an amazingly low 0.02% distortion.
