Customer Reviews

I like to listen to music anytime and everywhere I can.
There isn't much else to say... The HD650 renders the midrange very well, nestled between warm bass and clear treble.
Jeffrey Chandler
I can say that they're better than my Sennheiser 590's, and that is shocking.

So headphone.com calls them "simply the world's best headphone." I can't speak for the Grado or AKG contenders. I can say that they're better than my Sennheiser 590's, and that is shocking.

Which leads me to my first (and probably most important) point about this headphone. They cost a lot. A whole lot. Sennheiser has many units, including the 580, 590, 595, 600, and 650 (among many others), which could be construed as 'reference' quality. You'll spend about half as much on one of the 5xx models as you will on the 650. So if you were to ask me whether the 650 is *twice as good* (that is to say, it costs more in proportion to its increased capability), I'll tell you no, probably not. I might just not buy them, given the decision again. Perhaps if the price came down a bit.

At any rate, they are really a superb headphone. The sound is really incredible. You never really realize what you're missing in a recording until you've heard it through a set like this. You can hear the saliva in the back of a vocalist's throat. I'm not kidding. Everything is reproduced clearly, accurately, crisply, and I've yet to find any recording (Vocal, Classical, Electronic, etc) that can tax them. I suppose I'll stop trying to some day, but it's just wonderful to hear the headphones doing their job.

The construction is far more solid than the 590's are. Where there is plastic on the 590, you see metal and (no kidding) Kevlar. They are more attractive. They are also quite a bit heavier. They have a 1/4" connector instead of the more customary 1/8" mini connector -- this doesn't particularly bother me, I'll get to it in a minute.

Like the 590, they are an open headphone. That is, they are not "sealed" or "isolated".

As a lover of classical music I am a confirmed headphone listener. No set of speakers will offer the same amount of detail, most living rooms will add acoustic distortions, and many of us are not lucky enough to be able to play Mahler or Shostakovich at full power on a daily basis without getting into trouble with the neighbours.

For years I have been very happy with the Sony CD1700, an excellent headphone which is my point of reference for evaluating the HD650. The rest of my hifi set-up consists of a Marantz cd7300 CD player, PM7200 amplifier, and Musical Fidelity X-Can v3 headphone amplifier (a mandatory commodity if you intend to spend serious money on a headphone like this one). Also, I invested in the Cardas replacement cable for the HD650.

It is often said phones like this one need a 'break in' period. I used to regard this merely as snobbish audiophile technobabble - but found it to be actually true. Initially, I was less than pleased with the sound of the HD650, to put it mildly. Mid-range, mezzoforte strings (which make up a VERY large part of orchestral music!) sounded grey and weirdly disembodied. Stereo separation was exaggerated while the middle part of the soundstage seemed empty. Compared to the breezy, open sound of the Sony, the Sennheiser seemed compressed and less immediately involving.
Things were not helped by the fact that the wearing comfort of these cans is markedly inferior to that of the Sony. The HD650 has fairly small shells that are not ideal if your ears aren't quite that small. Also, they are clamped against the head rather tightly, which is not entirely pleasant. The Sony, by contrast, simply lets you forget you are wearing it.

But then, after about 50 hours of listening, things had changed rather much.

Verified Purchase
COMFORT: (Grade, B). The earcups are relatively deep, but not deep enough for ultimate comfort. Even after years of use, they don't let me forget that I have headphones on. On the other hand, the 650 feels much better than headphones with shallow cups that squash your ears (and make them sweat). The velour earpads can be replaced, which is good because they do wear down and attract dust. The ultra-soft, velvetlike velour is much better than pleather.

BUILD QUALITY: (Grade A-). The interior of the padded bridge is made of a hard, flexible metal that won't be cracking or breaking any time soon. The plastic bridge will break if you stretch it too much, so if you want to make the 650 less tight adjust the flexible metal NOT the plastic. The phones are sturdy without being heavy. After dropping them hard three or four times, they finally did require repairing, though. (One of the drivers got dislodged.) Still, these are very sturdy phones and don't feel cheap.

SOUND: (Grade, A-) Does the 650 have a "dark veil," as is often claimed? The 650 user's guide says: "In spite of all purism and the highest demands on precise sound reproduction . . . [t]oday many music-lovers want to feel the sound more instead of plainly analyzing it. The HD now captivates your senses where you used to be a mere observer. It allows total submersion into an ocean of music." I take this to mean that the main difference between the 650 and its HD predecessor is that it favors balance over precision. Some music tends to sound too bright (i.e., bass-impoverished) on headphones, so maybe Sennheiser tried to balance things by reinforcing the low end. Some people claim there is no dark veil, but then why does Sennheiser say "in spite of all purism"?
