High-End Headphone Cables

A good high-end headphone cable is about more than the most exclusive conductor material possible. What matters is the interplay of conductor quality, cable geometry, connectors, workmanship and mechanical properties.

High-quality cables use, for example, oxygen-free copper, particularly pure copper or silver-plated conductors. A carefully designed cable geometry and solid contacts ensure reliable signal transmission. The mechanical execution is just as important, however: the cable should be flexible enough to go largely unnoticed while listening, and should neither be unnecessarily heavy nor put strong pull on the headphones.

With high-quality headphones in particular, the quality of the connectors also plays an important role. Precisely manufactured plugs, stable transitions and clean strain relief increase not only reliability but also the service life of the cable.

A good headphone cable is therefore not automatically the most expensive or technically elaborate model, but above all one that suits the respective headphone setup electrically, mechanically and practically.

Replacing the stock headphone cable can make sense for a variety of reasons. A change in sound is not always the main concern.

A new cable is a good idea, for example, when the original cable:

• is too short or unnecessarily long for the listening position,
• is relatively stiff or heavy,
• tends to microphonics or distracting handling noise,
• lacks a suitable connector for the amplifier in use,
• does not allow the desired balanced connection, or
• needs to be replaced after long use.

For many headphone enthusiasts, feel and everyday usability are also important reasons to switch. A lighter and more flexible cable can noticeably improve comfort, especially during longer listening sessions.

Sonic differences are also discussed with high-quality headphone cables and are sometimes deliberately used by manufacturers for tuning. How clearly such differences are perceived, however, depends on the cable, the headphones, the amplifier and, not least, individual listening impressions. A cable should therefore not be chosen solely on the basis of a particular material.

Before buying a high-end headphone cable, first clarify which connectors are needed on both ends. Both the headphones and the headphone amplifier must be compatible with the chosen cable variant.

A common question with high-quality headphone cables concerns the difference between balanced and unbalanced connections.

With an unbalanced connection, the left and right channels usually share a common return conductor. With a balanced headphone connection, on the other hand, both channels are routed completely separately.

Connectors such as 4.4 mm Pentaconn or 4-pin XLR enable a balanced connection, provided both headphones and amplifier are designed accordingly.

Importantly, however: a balanced connection is not automatically superior in sound. What matters is how the respective amplifier is constructed. Some devices deliver more power at the balanced output or are fully balanced in design. With other amplifiers, the practical difference is much smaller.

Anyone able to choose between several cable variants should therefore be guided less by the connector type itself than by the design and technical characteristics of the amplifier in use.

The conductor material is one of the most frequently discussed characteristics of a high-end headphone cable.

High-quality cables are made from, among others, OFC copper, particularly pure copper or silver-plated copper. Manufacturers combine these materials with different conductor cross-sections, strand structures and cable geometries.

Copper is used particularly often in the high-end sector because of its very good conductivity and reliable workmanship. Manufacturers sometimes use especially pure grades of copper such as PCUHD or specially selected OFC conductors.

With silver-plated cables, a copper conductor is additionally coated with a thin layer of silver. Such constructions are deliberately offered as an alternative to pure copper cables and are sometimes described as having a slightly different sonic tuning.

A blanket rule such as “silver sounds brighter” or “copper sounds warmer” falls short, however. The conductor material is only one component of the overall cable construction. Geometry, conductor cross-section, connectors and the construction of the cable as a whole also play a role.

Accordingly, the choice should not be made on the basis of a single material alone.

Practical properties are often underestimated when choosing a headphone cable. In daily use, however, they have a major influence on listening comfort.

A cable for a fixed listening position, for example, may be significantly longer than a connection between headphones and a compact desktop amplifier. Too much cable length, on the other hand, quickly leads to the cable lying on the floor or getting caught under the desk.

Flexibility is just as important. A high-quality cable should move as naturally as possible and not constantly fight against its own shape. Very stiff or heavy cables can cause annoying pull with lightweight headphones.

A clean braid can also offer advantages. It contributes to controlled cable routing and can at the same time enable a robust construction.

One example is the headphone cables from Arachne Audio available at Level Audio. The hand-made cables rely on OFC copper and are available in different connector variants and lengths. This allows the cable to be matched precisely to headphones, amplifier and listening position.

Meze Audio also offers various high-quality cable variants, including versions made of particularly pure copper as well as silver-plated variants.

A headphone cable extension can make sense if the listening position is only occasionally further away from the amplifier or if the existing cable is permanently attached to the headphones.

With headphones with a detachable cable, however, a directly fitting cable in the required length is often the more elegant solution. This avoids an additional plug connection, and the entire cable can be matched precisely to its use in terms of weight, flexibility and length.

Anyone who always listens from an armchair, for example, can choose a longer cable straight away. For a desktop setup, on the other hand, a shorter cable is usually more comfortable.

A high-end headphone cable extension should therefore not automatically be the first solution. What matters is how flexible the existing cable system is and what distance actually needs to be bridged.

The ideal headphone cable should suit the entire setup of headphones, amplifier and listening position. Price or a particular conductor material alone are not a reliable yardstick.

Therefore pay particular attention to the headphone-side connector, the desired amplifier output, the right cable length, and workmanship and flexibility that match your listening habits.

At Level Audio you will find selected high-end headphone cables for different headphones and connection systems: from a flexible replacement for the stock cable to a balanced connection via 4.4 mm Pentaconn or 4-pin XLR.

The result is not an arbitrary “cable upgrade”, but a connection that suits your headphone setup precisely, both technically and practically.
