These audiophile/studio grade headphones from Sennheiser are the first item I've seen where 100% of the reviewing customers gave it a '5'. Their only complaint is that you don't want to use them with cheap gear or substandard source material: you WILL hear the flaws. We should all have complaints that the quality is too good, shouldn't we?

Solid performers built for people who take their sound seriously, with a frequency range from 10 Hz clear out to cat and dog range (39,500 Hz, human ears tend to cut off at about 22,000 Hz)! Uses a 6.3mm phone plug, but comes with a 3.5 adapter for your smaller items as well. Designed for hours of use at a time, they are both comfortable and lightweight. The units are hand-picked in pairs for best possible match between left and right ears.

If you're serious about your sound, order them and put them on your ears now!

5 out of 5 eggsTrue Musical - Magical Experience

Pros: Relatively low cost,

Cons: None so far

Other Thoughts: I could provide many reasons why I'm thrilled with the Sennheiser HD-650s but that would take too long. All I can say is they are MAGIC. Get yours at any price.

5 out of 5 eggsAmazing Headphones

Pros: Amazing clarity and response from these cans! Sound stage is fantastic.

Cons: None

Other Thoughts: To the guy who said he bought *high end* Skullcandy headphones and prefers them. There is no such thing as a high end pair of Skullcandy headphones, and the fact that you think there is means you shouldn't buy headphones like these because you clearly can't appreciate them.

2 out of 5 eggsgood quality not very durable

Pros: nice sound
comfortable on head than most

Cons: the earpads falls apart after awhile, become dirty
they are not worth $300
you can buy decent headphones for $50 every couple of years and make out better than dropping all this cash on these
I think I paid $150 for mine like 6 years ago, would not do that again.
dont handle dropping well

Other Thoughts: I bought some high end skull candy at marshalls on clearance for $50, I prefer them over these

4 out of 5 eggsA Chameleon. Terrific with an amp and terrible without an amp

Pros: Well balanced frequency response. Light weight and comfortable. Good for all types of music. Some Hip Hop lovers may not like their near perfectly balanced bass, mids, and highs. To them I say, "Keep your Beats and come get these when you're ready to listen to everything else."

Cons: Require a good quality headphone amp. The plastic construction has the look and feel of 'cheap'. The sound is first class.

Other Thoughts: My first impression of these headphones was that they were devoid of life. (See previous review) Everything non-complimentary statement said in that review is hereby revoked. With the proper headphone amp, these 'phones are spectacular! These are among a handful of headphones I've heard in recent months that I would recommend to my friends. They have a very pleasing, slightly on the warm side of neutral sound with extended highs. Bass notes have good weight in proper ratio to the mids and highs. A near perfect balance to my taste. The antithesis of Beats whose bass bloat obscures the lower midrange and overpowers the upper frequencies.

For this price, I would have hoped for a velour lined storage box instead of the decidedly cheap foam lined cardboard box. I'm willing to accept the thin plastic construction in trade for lightweight and comfort. I fell asleep last night listening to Nora Jones' CD 'Come Away With Me'. Which says a lot about how truly comfortable they are.

If you already own a pair of these and you think they sound just OK or pretty good, you are probably not using a headphone amp. You owe it to yourself to audition a couple of amps to see just how much better these are when paired with the right amplifier. This is not some subtle 'audiophiles only' difference. On a scale of 1 to 10, an amp raises these from a 2 to an 8. It's like adding a supercharger to a V8.

2 out of 5 eggsFirst Impression

Pros: 3.5mm adapter that works with my DragonFly USB DAC

Cons: These look and feel much cheaper than the photos on the web. They are made of very thin plastic. My Oppo BDP 105 has a built-in headphone amp but I can't use it with these headphones. 80 db is about as loud as they go. Tried them with my DragonFly with similar results. Evidently these are useless without a headphone amp.

Other Thoughts: Used as described above, these sound lifeless. There is very little high frequency. What little there is rolls off steeply. Cymbals have no discernible decay. I was very disappointed listening to Ted Hawkins - The Next Hundred Years (Mobile Fidelity Gold CD). Hawkins has a distinct raspiness in his voice that is completely obscured by these headphones. The song 'Biloxi' opens with a steady rythem of rim shots. They may as well be handclaps, because these headphones have no ability reproduce the leading edge transient of the thock! followed by the faint echo of the drum body. Another Mobile Fidelity Gold remaster I listened to is Pink Floyd's 'Dark Side of The Moon'. This is one of my all-time favorites, and I am intimately familiar with it. The opening of 'Money' is accompanied by the sound of coins being thrown into a cash register. The metallic ring that was evident even in my 1974 Koss headphones are missing in action with these. The sax sounds equally flat and lifeless, its reverb all but gone.

I am extremely disappointed with these headphones. I read many reviews, here, and elsewhere that claimed these could be used without a headphone amp. I do not agree! I also must assume that few of these reviewers have ever listened to quality headphones. They sound marginally better than a pair of $125.00 noise cancelling JVCs.

I am faced with an agonizing decision: Sell them, or buy a headphone amp and hope the sound will improve greatly.

The user guide included with these says that the public's listening habits have changed over the years and these were designed to cater to the way we prefer to hear music. If that's true, music must be dead, because these sound flat and dull. Instruments do not sound at all like instruments. I, for the first time EVER, listened to Dark Side Of The Moon without tapping my foot or singing along with 'On the Run'. The total lack of anything above midrange frequencies just sucks the life out of everything I listened to.

5 out of 5 eggsVery impressive

Pros: I decided on buying these after reading the forums for months about which set to buy first. These sounded pretty common for first timers, and they were right. The quality is out of this world, velour earpads are so soft, cable is pretty long, with an 1/8" adapter if needed. I've binged a whole series on Netflix using these, gamed for hours on the pc, and listened to music for hours, and never felt uncomfortable.

I have these paired with the Asus Xonar Essence STX headphone amp on my pc, and they are just awesome for everything. I made sure to download the unified drivers for it, like the Asus forums say, and haven't had one problem.

Cons: Price

5 out of 5 eggsI owned these headphones for over a year and were then stolen

Pros: These are one of the best engineered headphones ever created. I have heard my fair share of headphones and these are perfect for the beginner audiophile and even the experienced audiophile. I don't need to write much, there are books written in forums on these things.

I can wear them for hours and forget that I'm wearing them. Who invented on-ear headphones? Those were meant to torture you. These over-ears are incredible.

Cons: Replace the long 60 foot cable with a 4 foot silver cable from Geekria. 60 bucks. Can't go wrong.

Other Thoughts: The bass reproduction and the highs are in such harmony with these suckers. Where have they been all my life...? ;_;

5 out of 5 eggsThe Hype Is Real

Pros: If you are a gamer or hobbyist who wants to start getting serious about their headphones please do yourself a favor and JUST START HERE. The hd650's are a legend of a reference class headhone and for a good reason. For years this was Sennheiser's flagship headphone and til this day it holds its ground to headphones well above its price range. It's exceptional comfort allows hours (done 12 hours plus no fatigue) of listening sessions.

Cons: Investment: This headphone as you may know by now reading this review, is that this headphone has a fairly higher impedance which requires an amp to juice them up a bit and get the absolute fullest sound from them. How much you spend is up to you, go run to the headfi forums for amp reccomendations to fit your budget.

Other Thoughts: Delightful headphone to listen to for hours on end. I was never as huge of a jazz fan til I could ear the sure delight that comes from these when I play it =). Whether its gaming or flac file listening sessions this headphone just ends up being my go to choice for an all arounder.

I will say that if you are a heavy EDM genre listener such as myself there are some more notable options for over ear higher dollar headphones that have the particular low extension when compared directly to these. HiFiman's HE-400 is an exceptional choice for EDM tracks but for rock and hip-hop the hd650's are still a delight.

5 out of 5 eggsGood headphones

Pros: Comfortable
Sturdy construction
Sounds great

Cons: Cable is much longer than I need and it gets in the way. Its not something I would dock an egg over, as others may appreciate it.

Other Thoughts: Beware, these headphones are "open back" design. Using them in an area with external noise pollution can negate the quality of sound your paying for.

5 out of 5 eggsFantastic Headphones

Pros: I'll go ahead and leave a non-audiophile review for these headphones. I'm not the type of guy that spends hours at a time on audio forums, and not the kind of guy who has an arsenal of words to describe his audio experience. I'm just someone that places a high value on very good sound quality.

I'm 17 years old and I spent my own money on these, as you can imagine I had my reservations about dropping this much money on a set of headphones. That being said I have to say that it was money well spent, and I'll tell you why.

My setup: usb --> schiit modi ---> schiit vali ---> sennheiser hd 650's ---> my ears

before this I owned a pair of audio-technica ath-m50s

When I first put these on I felt a very slight clamp against the side of my head, I was a bit worried that they were going to be uncomfortable because I'm quite particular about how my headphones feel. After waiting about 30 seconds for your head to adjust to having them on they become quite comfortable. They are surprisingly light and with the open ear design that lets air flow through etc I often almost forget that I'm wearing them. They have huge ear cups too so your ears will be completely enclosed, so you don't have to worry about how they fit on your ears.

When I first tried these on I honestly wasn't very impressed. This is due to me listening to a bass heavy song, and it being an mp3. Don't make this mistake, these headphones will make you hear the bad quality in mp3s, you're going to want to get a couple lossless audio tracks. After downloading a couple of fully lossless tracks however, I started to feel more and more that it was money well spent. I could hear things that I had never heard before. The musician moving his fingers over the strings, the thud of a keyboard, the slightest breath of a singer, vocals that used to get drowned out by other things in the background. Its actually quite impressive.

The bass is deep and controlled, the highs mids and lows all sound perfect, and the experience is truly immersive. You feel like sounds are coming from all around you.

I love the audio on these things, and I feel very lucky to have an audio setup like this. If you can find a way to afford these, I highly suggest purchasing them.

Cons: Need a good digital audio converter (dac) and headphone amp to sound good. The headphones have a high impedance so the amp is absolutely necessary to drive these headphones. Also would you really want to convert your audio with the $2.99 card build into your computer? ew

I got the schiit vali/modi and I'm happy with it. Although I do have plans to upgrade in the future as I've heard that these headphones scale very well the nicer the amp/dac setup that you have.

Also you're going to need to re-download much of your music library. These things are wasted on mp3s, you can easily hear the imperfections that they have. Fully lossless audio tracks will sound much much better, as I quickly discovered.

If you're a bass head you might want to rethink getting these. Don't get me wrong the bass is deep, but its more controlled/refined than other headphones. If you want to listen to dubstep with these I'm sure other headphones will give you a more skull shaking/satisfying bass drop. For most stuff though the bass does sound very good and doesn't overwhelm any of the other sounds.

Other Thoughts: As a side note I had my mom listen to these and she heard the difference as well. She said that "It was like all the sounds are separated out, so you can hear each of them"
