Did you know?

Some time in use is recommended for these headphones to sound optimal. The HD 650 is not just for critical listening or classical music and is also often used by sound professionals in studios, for example, who understand that a high quality pair of headphones is crucial to their success. A dedicated headphone amp is definitely preferable, but not essential. A balanced cable will help you raise the stakes even further (CH 650S).

Sennheiser recommends this headphone for...

...those who have a passion for headphones and for music – and who want to enjoy hours of listening pleasure in comfort. These headphones are an ideal choice for the professional recording engineer recording classical music.


The HD 650 is intended for home use rather than portable listening.

    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!

    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.

    Verified Purchase
    Let me just start off by saying that I couldn't imagine spending almost £300 on some headphones, but these headphones have received so much praise across the audiophile community, and for good reason. In the end I decided to buy them and I am so glad I did.

    These headphones represent so much value, they used to be Sennheiser's flagship model before the arrival of the HD700 and HD800. The fact that they are still some of the best headphones you can buy for under £400-500 years later demonstrates how good these headphones really are.

    The comfort of these headphones is very, very good. In fact I couldn't imagine having anything more comfortable. Yes when you first put them on, the clamp is a little tight but these will loosen up the more you use them. Eventually you will forget they are even on your head.

    Moving onto the sound. These really do need to be used with a headphone amplifier and a relatively good DAC. Using these straight out of an iPod/Laptop is a waste of money as there are many headphones cheaper that will do a better job. When you do plug these into an amp and DAC these headphones will blow you away.

    I'm using a very modest setup. Fiio E7 + E09k. Will soon be upgrading to a tube amp, probably the Crack OTL when funds permit.


    The bass is actually perfect for me, I like to have some bass presence and punch when I'm listening to music. Too little and it will not sound engaging, too much and you start affecting the detail and produce a "muddy" sound. The bass is very clear and controlled.


    This is where these headphones truly shine. The mids are absolutely gorgeous, female vocals will send shivers down your spine. A very lush/warm sound.
