Sennheiser Orpheus HE90: What $16,000 Headphones Sound Like

In the early '90s, Sennheiser gave its engineers a mission: make the best headphones ever, irrespective of price. They came up with the Orpheus HE90. Only 300 were made. They initially sold for $US16,000. Today, they sell for upwards of $US30,000 on eBay.

The Orpheus is more proof-of-concept than anything else. Each set comes bundled with a dedicated tube amplifier (the HEV 90). There are six tubes in all, each protected by a metal casing. In the headphones themselves are high-strength glass and gold. The setup supposedly has a range of 7Hz-100,000Hz, which goes far beyond what human ears are capable of hearing. The amp has an LED that flashes as its warming up (yes, these headphones need to warm up), and a dedicated volume control. It will support up to two headphones, but if you want a second pair, you're looking at $US6,500, if you can even find 'em.

Components aside, the package looks absolutely gorgeous. It's something you would want prominently displayed in your living room, because it's a work of art. It looks more like it's something from the '60s, with its shining metal and its soft brown leather. The cups on the phones are very large and unless you have very large ears they'll definitely fit inside. Sorry, Mr. President. They are nicely padded, and they feel like something you'd never want to take off.

So, how do they sound? The clarity is absolutely unbelievable. There was so much detail, especially in the highs and mids, that it was almost like having your ear up against an acoustic guitar. It was so sharp that it was almost distracting, though I suspect you'd get used to it (and then get spoiled by it) over time. Vocals sounded incredibly natural and realistic. Sound was coming from a JR 800 Trans Rotor record player, which was playing Stockfisch Records Vinyl Collection 180g "Audiophile Vinyl Pressing". It was basically Cat Stevensesque folky stuff, so I couldn't evaluate the bass, but I've been told it's not as deep as more modern headphones. There is an excellent balance though.

So, was really enough to make me shed a tear? Not really. I was amazing and beautiful, but newer reference headphones (like Sennheiser's $US1500 HD 800, which I was able to listen to right next to the Orpheus) sound almost as good and will have fuller bass. At the same time, they do sound more... digital. The Orpheus is pretty much the ultimate in analogue. If you ever get a chance to listen to them, take it.

    I think you'll find it's the tubes in amp that needs to warm up, not the headphones. Warming down is usually more important, though.

    $250 headphones that come with a $15,750 valve amplifier.

    MP3's sound absolutely garbage on valve amplifiers. Only things that sound good on valve amplifiers are speakers and VINYL RECORDS !

      actually if you read a) the headphones themselves are $6k b) he was listening to a record. troll harder.

        Not sure if serious, or just angry at life.

    The Bugatti Veyron of headphones.

    Only in Europe.

    $30,000 headphones - sound really really really good.
    $200 headphones - sound realy really good.
    Suckers with too much money.

      He said in the article that it was intended as a proof of concept rather than a major commecial product.

      $200 headphones - sound realy really good

      No they don't, only "sound good"
      $1500 heaphones do sound "really really" good

      $300 headphones start to wane after a while. Audiophiles are like junkies, they're always looking for their next hit. Which usually means trying a whole plethora of headphones, DACs and amps. If one should have enough money or come to their end of their string, I can easily understand why they would want and appreciate something like this. After listening to perfection everything else is crap, so in the end they stop buying headphones and becoming a crazed sound/electrical engineer looking for something better.

    They're electrostatic headphones. So that means you're strapping some serious voltage to your noggin.

    You can even make a pair yourself, if you're game.
