    Still very good

    After all these years still a very competitive headphone


    The HD600 was was rated as one of the best headphones of its time and I think it is still very good. So how do they sound? Compared to cheaper headphones they impress with the added clarity and dynamics they reveal in the music. They are generally smooth and easy to listen to without the abrasive harshness you find in some competitors products. They have a well deserved reputation for being one of the most neutral sounding headphones you can buy in their price range. No particular frequency stands out as emphasized. The only slight criticism is that the sound stage is a little narrow. By this I mean the music is more "in the middle of your head" than some more expensive headphones. Over the years they have attracted much praise and a little criticism which I will briefly review. 1) Firstly, they are said to roll off in the bass a little too early. To my ears this is true for really low bass frequencies but mostly they sound well balanced in the lower registers. A little more punch and impact would be nice but they could not really be called bass-light. Even so for those who like a strong authoritative bass you may want to look elsewhere. 2) In the upper mid-range/lower treble they have been criticized for having a slight rise in their response. I find this is only very mild and not objectionable. In fact the mid-range quality is one of the best aspects of this headphone that reveals details you would not normally notice. 3) Some think treble frequencies possess a "veil" that limits clarity. Compared to the best headphones I find the very extreme treble may roll off a touch, but this means they are less likely to induce listener fatigue. The treble is a good balance between sounding smooth and yet having enough attack and vibrancy. However, on poor recordings some may find the HD600s can sound a little "bright" (i.e. give an emphasis to treble sounds). Comfort is very good with large squashy ear-pads that cover the whole ear. Weight is very reasonable so they can be worn for long periods without feeling heavy. They do clamp your head a little tightly at first but are very comfortable once you get used to this. Resist any temptation to bend the headband! A few weeks of use and you will not notice the extra pressure. These are open-backed headphones which means air can pass through the back of the ear cup to the speaker element. This means there is no sealed enclosure and sound waves cannot cause distortions inside the headphones. The disadvantage is there is no isolation from external sounds. You will be able to hear everything happening in your environment just as if you never had them on. Similarly anyone sitting fairly close to you will hear what you are listening to. Therefore, apart from the large physical size, these are not suited to wearing whilst commuting! Quality of construction is more than adequate and spare parts are readily available. However, these are not the kind of headphones to abuse. The metal grilles will dent easily so treat them with some care. They have a marble effect finish that can chip if treated roughly. The cable is 3 meters long and is a bit thin, but it does have a very nifty built-in adapter to convert it to a 3.5mm socket. Although Sennheiser have improved this from the early examples, unplugging the cable from the headphones frequently can lead to the connectors becoming loose and making intermittent contact. By modern standards their impedance is high at 300 ohms. This means anything portable that is battery powered like a phone will may struggle to drive them to a high enough volume. Most mains powered equipment will probably have enough power, but these headphones will either reveal poor quality or just not perform as well as expected if you partner them with mediocre equipment. If you listen to audio via a computer get a good sound card or a headphone amp or amp/DAC combined.


    Poor isolation from external sounds. To really shine they need good partnering equipment with a good headphone amplifier.


    Enjoying music at home. They are too large for portable use.

    Such an open sound-stage, beautiful!

    This is my second pair of HD-600's, the first pair went for 10 years & I basically just wore them out. Diaphragms & circuitry however were still fine at the end, HD-600's are tough, just the padding, cups and any foam/fabric on the cans had been destroyed by a humid climate + sweat. HD-600's have always been my favourite Sennheisers...love them!


    Crystal clear, warm bottom end, great open sound-stage


    Can be a little tight to start with, but they do loosen up over time. This is very minor & nowhere even near being a deal breaker


    Mixdowns, your favourite tunes, gaming...anything and everything!

    Sennheiser HD600

    I purchased a pair of these in 2003 (cost at the time was £250) along with a Musical Fidelity X-Cans V2 Heaphone amplifier and the sound amazed me. I sold them on as i had very little time to use them in the home as i was always away and i can assure you that i tried to get along with them with a iPod which could not drive them.


    Superlative studio-home use headphone, fantastic detail retrieval, very well made, the number one choice for years and years in very good quality headphone.


    They need a very good headphone amplifier to get the best out of them, high impedance headphone that demand a fair bit of power to drive them, definitely not for mobile or 'on the go' use.


    Home use, studio mastering.


    I would recommend this to a friend.


  • What amplifiers are recommended for Sennheiser headphones?

    Other than recommending the Sennheiser HDVD 800 and HDVA 600 amplifiers for our high end audiophile headphones we do not provide amplifier recommendations because there are simply too many factors (including cost, features, etc) that need to be accounted for when choosing an amplifier.

    For amplifier recommendations Sennheiser suggests that our customers check out this headphone forum (www.head-fi.org) where the moderators and member test a variety of different amplifiers of varying costs and features and can provide feedback on how the different amplifiers perform under different circumstances.

  • What is the difference between "open" and "closed" ear cups on headphones?

    With Sennheiser headphones the audio will always be accurate and responsive and is sure to please no matter what situation you need it for.

    An open (sometimes referred to as "open aire" headphone is one that uses some external airspace to reproduce life-like audio within the ear-cup. Think of it as having premium speakers next to your ears that you can control the volume for with extreme precision. The trade-off is that at extreme volumes some sound will leak out. Some of our "open aire" models include the HD 800, HD 700, HD 650, HD 600, HD 598, HD 558 and HD 518.  

    A closed headphone isolates you from your environment and vice-versa (ie: the sound is contained within the headphones). This is perfect for critical listening or a situation where you do not want to disturb/be disturbed. Some of our "closed" models include the MOMENTUM, Urbanite XL, HD 380 PRO, HD 280 PRO, HD 449 and HD 439.
