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.

Compatibility

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

    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.

    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).

    5 of 5 people found the following review helpful By Sebastian Knuckledick on 27 Nov. 2014
    I had the opportunity to compare a pair of Sennheiser HD650s with a pair of Philips Fidelio L1s at a friend's house recently. The source was a Nottingham Analogue Spacedeck turntable fitted with a Rega RB250 tonearm and a Nottingham Analogue cartridge. (This is a superb turntable and sounds wonderful!). The amplification was a World Designs HD3S valve headphone amplifier worth about £500. To cut a long story short, after extensive listening over several hours with a variety of material, I much preferred the sound of the Fidelio L1s as I found them far more enjoyable and engaging. I understand that both sets of headphones are in absolute terms regarded as coloured. The HD650 is of course known for its fuller bass when compared to the HD600, which many feel is the better headphone. However one feels about such coloration of the sound, the most important aspect for me is whether what I'm hearing gives me pleasure and fuels my desire to spend long periods of time listening to music. The Fidelio L1s do this in aces. BTW, both sets of headphones have had many months of use.

    With regard to the HD650's build quality, I thought it was good but it's not in the same league as the L1s which are very well made and use high quality materials. I also noticed that the paint on the HD650 had started to craze along the lower edge of the headband. Not particularly impressive in a pair of headphones that were until recently approximately £350. They were, however, very comfortable to wear and felt lighter and less apparent on the head than the Fidelio L1s, which I also consider to be very comfortable. The ear openings on the HD650s are also nice and wide and should suit the larger-eared amongst you.
