Details

Here we have a tweaked version of the world renowned Sennheiser HD600 headphones. We take a standard pair of HD600s and make a couple of modifications to the driver to make them sound less veiled and improve their low frequency square wave performance. We also replace the stock cable with one of our ultra-low capacitance litz copper cables, terminated in a choice of jacks or wired for use with a balanced output.

The drivers on these have our new CNC copper shaped mass loading kit installed - it not only gives more detail across the frequency range but also comes with inserts to allow you to tune the bass levels to your personal prefference - they come shipped with what we considder the most balanced option. For the bass heads there are two levels of bass above this and for those that want a bit more mid / high there are two inserts with lower bass levels.

These headphones also include one of our ultra low capacitance cables with a choice of colours and connectors

  1. What material is the wire made of and why?

          Our with is made from OFC Litz copper. Each core is made up of 84 individually insulated strands of 0.071mm diameter copper. Each core is roughly 1mm across which equates to 18 AWG. They are held together by natural silk fibres and covered with an over sized nylon outer cover to give a decent air gap between cores.
    1.1 Why OFC copper rather than OCC or Silver.
    For the same cross-sectional area, silver is about 7% more conductive than copper but if you double the cross sectional area you can roughly halve the impedance so it is much cheaper to just use more copper to get the same improvements. By using a thicker copper wire we can get better impedance figures then a thinner silver cable. OCC has some definite advantages but being more flexible but as our strands are so thin the wire is very flexible already.
  2. What is the advantage of Litz vs stranded copper ( Skin effect )

    With a standard stranded copper wire ,as charge can move from one strand to another, they act as one thick solid conductor.
    Skin effect pushes higher frequencies out to the edges of the wire meaning they are traveling through less of the area of the cable. The skin depth reduces as the frequency increases so on thin cables it is not a problem for audio frequencies.
    In our Litz wire, each strand is individually insulated from each other so they act like 84 individual thin very wires rather than one large one. This ensures that despite the increased thickness of our wire, there is no skin effect until the frequency gets over 700khz so even the highest rez audio will not get rolled off at the top.
  3. What is the capacitance and impedance of your cable and how does that effect things.

    Our cables have some of the lowest capacitance of any that we have tested this was one of the main goals we had when designing it as capacitance it most likely to give an audible effect. Typically one of our cables will have around 20pF – 40 pF for a 2m cable depending on the connectors used. As a comparison, A standard HD600 cable has a capacitance of 600pF
    The impedance of a capacitor changes with frequency which is why we try to keep it as low as possible.
    Our wire has a DC resistance of 0.05 ohms per meter which is very low and as we keep the capacitance and skin effect incredibly low it gives a pretty much perfectly flat impedance across all audio frequencies from 1hz right up to 100+KHz
  4. How does your cable sound?

    As mentioned above, our cables are designed to keep the signal as pure as possible with a perfectly flat response. We believe you should not use a cable as “tone control” and the sound is as good as it is going to get as it leaves the amp – the cable’s job is to get the signal to the headphones without adding or removing anything from the sound.
  5. What are the ergonomics like?

    Ergonomics are almost as important as the electrical performance – You could great sounding cable but if it is stiff or heavy it can be distracting and spoil your listening experience.
    Despite our cables being “thick boys”, as they are mostly air inside to give an air dielectric, they are actually quite light and very flexible. As the cable has a bit of spring to it, it can also reduce the pressure on your equipment if you accidentally yank the cable.

What sort of warranty do you offer and what If I change my setup in the future?

We offer a 2yr warranty on all of our cables so if you get any problems just message us and we can repair of replace it for you for free any time in the 1st 2yrs.
We are keen for our cables to stay in use for as long as possible to help prevent waste and save the environment. If your cable breaks outside the warranty period we offer cost price repairs and if you should buy a different amplifier or headphones in the future, you can send the cable back to us to be alte
