I have owned a pair of these headphones for almost a year now, and the sound they produce is quite simply divine. The first time I put them on, I felt the pads did press quite hard on my head, considering what I was expecting from reviews. After a little tweaking of the headband, I found them to be more comfortable and once I had been wearing the phones for a couple of days the pads softened. The result was the most comfortable fit I have ever experienced in a pair, and believe me I have worn many a pair of headphones..
I think after stumbling upon the review below, I felt compelled to leave my feedback as I thought the reviewer seemed truly misguided. The sound these headphones produce, while not completely geared towards a completely flat response (as this was the idea of the 600s) is very truthful. You will find that if you have not been subjected to 'proper' sound, for example in a studio environment, you may think that they sound perhaps different to what you would expect. The average person's opinion is perhaps generally that one wants lots of deep bass and high treble to create an 'impressive' sound. While this may impress, at the end of the day one has to fiddle with equalization controls to adjust the sound for different records, as not all of them will sound good. The reason for this would be that the sound the equipment (speakers or headphones) is producing is not a balanced sound. One will probably, for example find that some records appear 'harsh' on the ears when up loud on a lesser system, and this would be the fault of the listening equipment. There are many other factors that would make this review too long, but the general idea is that if you want to hear exactly what the producer created in the studio, then you want something that matches the 'standard' of sound as closely as possible.
I have been producing, recording, editing and listening to music for many years and these headphones represent what I would consider to be some of the best in headphone sound quality. I actually think that I will never want another pair to replace them.
Decent sound comes at a price, as the materials chosen have to be picked and put together extremely accurately so as to perform exactly as required. Creating accurate headphones is an art, and Sennheiser's many years of experience has clearly lead to their producing headphones of such a high quality. To think that a company with such experience in building accurate devices such as these would place a piece of material in their headphones that degraded their sound is completely ridiculous. Do you really think that a company that invests so much money in developing accurate drivers would sully their reputation and bring down the quality of their high end products by not considering such a thing? I think not. The headphones were designed to be used as they are presented, no changing of cables and ripping out of integral parts will make them more accurate, in any case it will probably do the reverse.
On a brand note, I did have the opportunity to experience Some high-end Sony DJ headphones, which did sound quite good until I compared them to the 650s. The immediate thing I noticed as the harshness of the Sony sound. Playing 'Hunter' by Bjork, I found that the vocals became ear piercing on the Sonys, yet remained silky smooth and accurate on the 650s. All the separate sounds in the track remained clear and were never drowned out, a problem I discovered with the Sony earphones.
(if looking for high quality headphones I highly recommend this track for judging the quality of the midrange, (something often overlooked) as the vocals really push the equipment you are listening to to it's limits and at high levels will really sound painful on anything of a lower quality)
The bottom line is, if you are looking for headphones that will impress the un-trained ear, then go for some of a lower calibre. Perhaps consider some sub-£100 Sennheisers, as these are of a pretty high standard and probably will sound better than most of the other 'high-street' brands. If you are, however looking for a pair of headphones that will give you the true sound of your records and will probably make you hate every other piece of sound equipment you have ever listened to, then buy these. The quality is superb for all genres, and until you have sat down and watched a big budget film with an orchestral soundtrack on these cans, you do not know what you are missing.
** You do not need ridiculous hardware to appreciate these headphones. Integrated circuits today are of such a high quality that even cheap amplifiers (as long as they have the EQ turned off) will produce a decent sound. The only thing one has to worry about is how powerful the amp is. I found that my friend's iPod for example did not really have enough 'kick' to turn these up loud. Not all portable devices have the same output power and I am sure to some 'audiophile' reader's disgust I should point out that I had the opportunity to try the 650's on a sub £10 CD player, and they sounded just as good as they did when plugged into my hi-fi. A lot of this expensive CD player business is just a great big con!

There has been a lot of talk in the reviews about the use of headphone amps in realation to the quality of these headphones. Without wishing to veer off on to a completely separate discussion, I just wish to make the following point:
These are a quality pair of hi-fi headphones. If you do not use a headphone amp, they will still sound great. If you do use one (e.g. Grahma Slee Solo), they will sound even better.
If you are looking for headphones to use with an iPod or similar device, do not buy these. They are hi-fi headphones (i.e. not designed to be portable or driven by low output equipment). Your money would be far better spent on a pair of B&W P5s or Klipsch Image X10s which will give you far better results from that kind of source.
Do not jusge these headphones (or any headphones, for that matter) straight out of the box. They sound muffled, veiled and distant, like they are full of cotton wool. Give them 50-60 hours to burn in and they turn into a completely different beast.
Gone is the distance and the veil. Music sounds a lot more immediate and focused. The soundstaging is excellent, giving the impression of space. The music is presented as if it were coming from speakers either side of you (which it effectively is) rather than being piped directly into your ear.
The level of detail and clarity at this price is stunning. Mid-range and vocals are stark without being harsh. Bass feels tight and responsive. They do what all good audio equipment aspires to do - present the music as it is intended by the source. There is no colouration, no quickening, no 'enhancing', just clarity.
I have heard detail on records and CDs that I have never heard before. I suddenly want to dig out everything from my music collection and listen to it all at once and fall in love with it all over again. I feel like I am discovering my favourite bands and artists for the first time.
In my eyes, that is the highest recommendation of all.
NB. This review is my opinion of these headphones. Your ears are different to mine. Just because these are a great pair of headphones to many, does not mean they will be to all. Some people just do not get on with Sennheisers, others may have systems that do not match (I have heard that these do not match well with a valve orientated set-up). All headphones have their own characteristics - it is important to find what works best for you.
Other headphones in a similar price bracket include Grado 325is and AKG 702s, both of which are excellent and well worthy of an audition.

Contrary to a couple of other reviewers who have stated that these will not sound good without a quality headphone amplifier - balderdash! I own a quality headphone amplifier, and whilst this doubtlessly improves things (as one would expect) the HD650s still sound excellent when plugged directly into my CD player or even my Hi-MD walkman, no problems driving them at all. And the supplied literature backs this up, stating that they can be 'directly connected to stationary hi-fi components of the highest quality' - well, admittedly, whilst mine are good they are not the HIGHEST quality, but nevertheless, these phones have no trouble delivering. But, yes, a dedicated headphone amp does take things to the top level.
And the sound - it is close to perfect. The bass is completely realistic and well extended, rather than overblown or muddy as is the case with many cheaper phones. The high frequencies are naturally airey and clear, making for relaxed listening without the need to push the levels too hard (unless you really want to of course).
The mid range is sounding very clear and undistorted. These cans have only been out of the box for an hour, and they have a recommended run-in time of at least one or two days constant useage, so I only expect this already wonderful sound to improve further still.
Comfort is not a major issue. The earcushion on each of the cans fits very nicely around each ear with room to spare (for my 35-year-old ears anyway). The pressure is, however, just a tad too tight on the sides of the skull (but I can cope - and maybe they are expected to loosen with age). The literature also states that the pads should be replaced periodically for hygenic reasons, but I can't work out how these are detached since they appear to be stuck very securely in place. I've already tried pulling as hard as I dare without the risk of ripping them. So I don't get it.
Anyway, the earcushions (in theory), along with the 3 meter cable (which does detach easily enough from each of the cans) are replaceable, to extend the life of the product.
And it all comes in a hard box with a hinged lid.

As a former Beats Pro owner ( Yes I know... it was an impulse buy ) I was used to listening to my music with the base turned way up. I decided to go for something more high-brow as a replacement and after reading several reviews, I decided to go for the HD650.
The headphones arrived in a beautiful box ( as you would expect for the price ) and although they feel slightly plasticky, the robust build is something I can't argue with. They feel like they'll last me a lot longer than my now defunct Beats.
As far as sound goes, these are not the type of headphones you are going to run from your iPod or phone. I am using a Fiio E7 portable amp ( will shell out for a more powerful one eventually ) and listen to mainly FLAC files and Spotify. At first I was slightly disappointed by the sound, having listened to the Beats for the past two years.
The HD650 sounded flat, muffled and not very powerful. I've been braking them in for three days now, and I am simply astonished by the improvement. They sound so damn crisp and warm - they just make me appreciate music on a whole new level. The Beats had bass I could feel, but the HD650s have lows that are not intrusive and let everything else about the music shine, especially the vocals and high notes. It's a pleasure listening to them, and honestly, I have re-discovered my music library. I can now just sit and listen to a song with my eyes closed and appreciate every single little note that goes into it.
My old Beats Pros were more powerful, louder and had a lot more bass, but that delicacy in the music that I have found with the HD650 is lacking, and I'd have that over the bass any day of the year. Honestly, best 330 quid I ever spent. I am loving my new-found music enjoyment and I am looking forward to upgrading my amps and music collection.
My only complaint is the hyper long cable ( not bad in its own right ) but I wish Sennheiser supplied a second shorter cable as this one gets tangled in my legs quite a lot.
Apart from the, the HD650 are just brilliant. I feel like such a knob end for having used the Pros for so long. I love music <3 :)

I do not intend to get technical, but will simply focus on my experience of using these headphones over the past year. I will identify the key weaknesses and assets of these headphones.
1) - At nearly £200 they are considerably more expensive than the average headphones.
2) - Your speakers will probably sound awful when you take your HD650s off.
3) - They are a bit uncomfy (see asset 4).
1) - They come a in fab presentation box which is a good (though unrequired) bonus.
2) - They allow you to hear the most subtle detail - for better or worse.
3) - They sound great with music, TV and film (especially modern programmes and films) and playing games on the PC. For example, Stargate SG1 is amazing - you feel like you are there.
4) - The more you listen to them the comfier they get. I can use them for hours and not really notice that they are there i.e. they become comfortable in time.
5)- They are upgradable via specialised cable such as Cardas.
If you are thinking about buying these, but are not sure, consider the following.
1) - Spending money on these does not mean that you will have no money to buy more cds, currys, clothes or whatever. All the other things you want to buy will be there next month and the month after that and so on.
2) - Your next wage is probably only 4 weeks away at the most. If you've never starved in the past, you probably won't starve if you buy these.
3) - If you buy these you can rest assured that you will not have to buy a new version 6 months from now. As headphones have been around much longer than new technologies such as the mobile phone and mp3 player, headphone technology has already matured past the initial design and redesign stage. Headphone technology is pretty stable and established. Therefore, these headphones can reliably be claimed to be more or less at the pinnacle of headphone technology.
4) - If you buy a punto, you get a punto. If you buy a Daimler, you get a Daimler.
5) - Go and buy them!

I got these headphone to fit in to an all-Naim system. Naim have a reputation for delivering on pace, rhythm and timing, and after reading a great review in What HiFi, I thought these would deliver. My old headphones were a pair of Beyer DT990's which were comfortable and easy on the ear, in both physical and musical terms. They could be listened to all day with no fatigue. They were blown out one day whilst connected to the computer, so I decided to have a change, in spite of the fact that they are still made.
I am fairly useless at judging the sound of stuff in HiFi shops, no matter how helpful they are... and the pressure of making my mind up in those enviroments has often lead to poor decisions.
I am pretty pleased with them so far. I am using them with a (non-naim) Musical fidelity X-can3 headphone amp and the sound is crisp, clean, fast, revealing and well-defined, with huge dynamic range. Bass is articulate and well extended. In my system, although the sound could never be accused of being harsh, there is a slight tendency for them to be fatiguing at higher volumes... so in a hard sounding system it might be worth considering something like the Beyers. If the system is balanced, or tends towards warmth, they would probably excel.
The quality of construction is first rate, and the speakers fit completely over the ear, the vellum pads being very comfortable. The headband is a little tight on me, causing the phones the feel as if they are clamped to my head, which, although they are not uncomfortable, it's a bit of a relief when removed after a session. The open backs allow outside noise in easily, so it is a little easier to hear the phone or doorbell.
All in all, they are a good buy and sound great in a well balanced system.

I am a long-time headphone user and recently decided to upgrade my ageing Sennheiser HD600s. First I went fot the highly regarded AKG K701s and although they were very good after several weeks I found they were simply too uncomfortable to wear for long periods. I then tried Grado SR-225s, which were very disappointing indeed. In particular they felt cheap and nasty - certainly not up to Beyer or Sennheiser in terms of build quality - and the sound seemed merely average.
Then I bought the Sennheiser HD650s and...Nirvana. Build quality is excellent (the cable is much sturdier than that on the HD600s) and comfort is streets ahead of the AKGs (though they fit more snugly than the HD600s). But it was the natural sound that bowled me over, not to mention the extended bass and sweet treble. I listen to classical music and believe me these cans are the business. For the first time in a long time I can't wait to get home, pop in a disc, slip on the Sennheisers and just enjoy the music.
Are they a worthwhile upgrade from the HD600s? I'd say so, especially if you have good-quality kit. They are leaner sounding but more natural and extended. And the detail and nuance you can hear is just astonishing.
It's been a long journey via Beyer, Grado and AKG but I've finally found some cans that really sing. Unreservedly recommended.

I have been using these for a few days now and I have to say they exceeded my expectations. I have been using the HD 598s almost daily for three years now. The reason I got these is because I was dissatisfied with the low end on the 598s.
Just some background; I have owned the 280 pro, HD 518, HD 598, and now made the jump to the HD 650. I will be comparing these mostly with the 598s and the 518s.
As far as comfort goes they compress the head a bit more than the 598s and the 518s, but they are not uncomfortable. The only noticeable discomfort would be below the ear where the bottom of the can presses against my jawbone. After a few hours this starts to annoy me, but simply moving them around provides relief so this is nothing. I would definitely say the 598s are more comfortable for extended periods, but the 650s feel more solid on the head. I haven't experienced any major warm spots even after long periods of use. The cans do keep my ears warmer than the 598s, but nowhere near as bad as the 518s used to. My main complaint about the 518s was how hot they would make my head due to the lower quality material and padding used. The 650s are nowhere near the 518s in this regard. Also, the headband on the 650s is narrower than both the 598 and 518. I found this to be a very noticeable difference since the compression is higher and have had to adjust it often. It just feels weird, but this is something I'll get used to with time since I've been using the 598s for so long.
The build quality is extremely solid, but the plastic feels cheaper than I would like. It doesn't make me feel uneasy about breaking though. This is mostly the outside of the cans and top of the headband. The outside grills are metal and the cushions are high quality. The included cord is nicer than what comes with both the 598 and 518, but is special since the 650 uses one input per can. The included 1/4 to 3.5 adapter is way better in my opinion since it has cord length. The included adopters with the 528s and 598s were a single adapter piece which looked like a freakishly long Frankenstein plug when used with a portable device. This adapter keeps the cable end at the typical 3.5 size so it looks normal and doesn't cause unneeded stress on the contact or the output jacks. The old adapter actually caused me to break a couple laptop outputs while being careless. I wish this adapter was included with all the other models.
I'm no experienced audiophile so I'm probably going to sound like a child explaining the sound. These have been described in other reviews as being "dark" sounding. I'm not sure what that means, but after using them I think I kind of get it. My 598s were very bright and almost airy sounding. The treble was very distinct, the soundstage was amazing, but the bass was very low key and had little impact which is good in some cases. The 650s definitely have more bass impact and I can concur that it is "punchy". I can enjoy electronic and hard rock on these much better. While the bass is heavier on these it is still crisp and accurate, not boomy or overpowering. The treble is still very present, but does seem a bit rolled off to me. The sound is not what I would call bright at all, and the soundstage is definitely smaller than the 598s. The overall sound seems more focused and impactful in comparison. I am amazed at how much more detail I was able to pick out in some of my favourite songs which I thought was impossible at this point. These really surprised me at how clear the entire range was. Now for web videos or Skype calls these were not as enjoyable to me. These made me well aware that I was not listening to high quality sources and since the sound is more focused and narrow when compared to the 598s voice calls can actually annoy me. This was something the 598s do extremely well, but this wasn't the reason I purchased these.
I guess it should be mentioned that the sound leakage on these is much higher even when compared with the 598s and 518s.
These headphones are hard to drive. It's been said everywhere and should be expected given these are 300ohm cans. I haven't had much experience with high resistance headphones so this is venturing into new territory for me. I had a small fiio amp with my 598s which increased the quality, but wasn't really needed for my main application so I got rid of it. I can DEFINITELY see where I would want that back now. Forget about using these with something like an iPhone. At max volume these were so quiet I couldn't enjoy them at all. On my 15" MacBook running boot camp I was only able to achieve a moderate volume with a few software tweaks that I would never use daily and hindered the overall sound. Now, my MacBook running OSX was actually able to push these fairly well. This is the only way I have to actually enjoy them right now. The sound is great and depending on the track, the volume could go above my comfort level with OSX. I will be purchasing a dac/amp combo for my system very soon and I feel like this will really open these up and sound even better. I should have factored this into my price, but luckily I have my Mac that can push these decently until I save up more.
The price on these is very reasonable. I'm a little mad because I payed the same for these as I did for my 598s at the time. Also, I think this is the only time ive seen UK Amazon have a better price than the US on these. I was able to save about 100 usd on these even with the VAT and shipping.
Overview: I really like my decision to "upgrade" to these. I quoted upgrade because it really can't be said that these are better than my 598s. Each has a noticeably different personality and I'd say it all depends on the application. The 598s excel in acoustic listening, voice calls, and movies due to its wide soundstage and crystal clear upper range. I wanted to move from the 598s because my heavier bass heavy music was lacklustre and the highs would get fatiguing to me when listening to the majority of my music (rock). The 650s definitely excel in the music department with a more focused sound and deep, quick, bass with some punch without sacrificing quality of the rest. They do not do well with lower quality sources or voices using Skype. I am very satisfied with these though since I bought them to relieve the bass situation I was having with some of my favourite music.

For years I have been frustrated by the sound of headphones which didn't live up to the sound that came out of my speakers, so with that in mind I did some research into what would give me the results I was looking for, so after reading various reviews in magazines I found that this model of headphones HD650 which was given 5 stars in February 2004 by "What Hi-Fi" and was made an "editors choice" by "Hi-Fi Choice" about the same time made these headphones look like a better buy than the older HD600 model I had been looking at so after hearing both, I took the plunge and acquired a pair of the newer HD650 for myself.
The headphones come in stiffened grey card box, which has chrome hinges; the box is lined with dark grey foam that is cut to fit the headphones exactly.
The box also contains a gold-plated 3.5 jack adaptor for use with walkmans Ipod's and other portable sound systems.
Inside a clear plastic pocket comes the manual and the 2-year warranty certificate which just like the manual is written in English German French Italian Spanish and Swedish and has a list of Sennheiser distribution centres.
The headphones are sliver titanium in colour.
This text is from the manual:
With the HD 650, sennheiser has followed the changes in the listening habits of music- lovers and the way in which they experience sound. In spite of all purism and the highest demands on precise sound reproduction, a slight change n listening behaviour is detectable. Today many music-lovers want to feel the sound more instead of plainly analysing it. The HD 650 now captivates your senses where you used to be a mere observer. It allows total submersion into an ocean of music and lets you completely forget your surroundings.
Come and enjoy this unique listening experience.

All you tech heads out there I hope all that means something to you because it means nothing to me, all I know is that at last I have a pair of headphone that envelope me in sound and are not painful to wear after a couple of hours wear and sound superb no matter what genre of music I play and create a true hi-fi experience with astonishing resolution and tone that are a joy to listen to, a true audiophiles dream, expensive but worth every penny for the years of pleasure they will bring me.

Ok, i am not an audiophile, i want to be, but i am not. I dont have the budget for it and i am not in pursuit of that pure sound that i hear many audiophiles talking about.
I know what i like things to sound like, this may not be right in the audiphile sense, but it makes sense to me.
I purchased these headphones after reading several reviews and i just want to say they are FANTASTIC!
I use them for Gaming on my PC (shock horror) Watching Movies and also listening to music, everything from rock to classical.
You dont need £00000s of pounds worth of kit for these headphones to let you know they are special, that being said they need a fairly reasonable system.
Ignoring all other tasks i set before my headphones, and just concentrating on music, i can say these headphones will deliver you a perfect, very clean, natural sound.. things sound as they should. a cello is clearly a cello, wind instruments sound like they should.. Odds are if your a regular person like me, you wont understand fully until you hear these headphones and audition them against other types. I am told the top end is rounded off very slightly, this my poorly trained ear will have to just agree with. What i can say is the sound is just right.
I then use an EQ to bring the bass to where i want it, the mids, the treble... and across the world many audiophiles who read this and are calling me heathen. But my modest little system and these headphones give my ears the sound that i want, and it is crystal... perfection!
These were an upgrade for me from the HD555, which i also recommend, but really.. if you have the budget these are the best headphones i have ever heard!
