With a price of almost $1300 the new Sennheiser 800 headphones better be special. Well, they are. Hand built one at a time, the 800 employs a patent-applied for ring-shaped transducer made with a precision wound wire coil that’s only 42 micrometers thick. It has 3.5 layers of wire with exactly 98 windings. With a frequency response that ranges from 8 to 50 kHz the Sennheiser 800 sounds as smooth as it feels. It’s easily one of the most comfortable headphones I’ve ever worn, and if I could have managed it I would have gladly continued wearing them all day…BTW, that's not my head.
