Nearly 25 years ago Sennheiser introduced its Orpheus headphones, which were widely considered at the time to be at the leading edge of headphone design and quality – they cost US$16,000. For the last 10 years, engineers at Sennheiser have been trying to improve upon that original design and they've now produced a successor. The company claims the new Orpheus are the "best headphones in the world" – and they come at an even higher price tag of around €50,000 (US$55,100).
Though open high definition headphones like Sennheiser's wonderful HD 598s or the mighty HD 800s can offer greater spacing and a more natural airy feel than closed-back designs, they can't really be used in anything but the quietest of environments so listening on the move is simply not an option. The German audio brand says that it's new HD 630VB headphones offer hi-res music lovers a balanced, airy and audiophile-grade listening experience with the benefit of effective passive noise isolation.
