Headphone cables might be one of the most controversial topics in the world of audio fidelity. Do they actually affect the way your headphones sound? It’s surprising how polarizing this discussion can be among long-time audiophiles, and at least in my experience, people tend to hold on to their opinions, no matter what proof you have for one side or the other.
Today I decided to tackle this sensitive topic. I’ll discuss if and when it’s worth upgrading your headphone cables, and what you should go for if you want to get the best experience with your cans. Let’s dive in!
Is a cable upgrade worth it?
Whether it’s worth it or not depends largely on how “bad” your stock cable is, and what you’re expecting from your new cable.
Headphone designers focus most of their attention on, you might guess, the actual headphones. While high-end audiophile cans may come with equally exceptional cables, most manufacturers see them as something dispensable, which is why many audiophiles see in upgraded cables the possibility to improve sound quality. And it is precisely in the listener’s expectations that the problem lies.
In my experience, based on my research and tests, there’s no quantifiable improvement in sound quality when it comes to upgrading headphone cables. Sure, high-end cables can have better shielding, conductors, and connectors; in some cases, they might make your headphones sound louder. But is there a difference in the frequency response? Unless you’re replacing a faulty cable, or have headphones with extremely low impedance, the short answer is no.
Thick, low-impedance cables are more conductive and, therefore, can make the volume louder when using low-impedance headphones. But once again, an upgraded cable won’t bring a measurable difference in the frequency response.
Connector types
Let’s take a look at the type of connectors you might be looking for when upgrading your headphone cable.
The most common type is the 3.5 mm aux (1/8-inch) connector, which you’ll find on many headphones and mobile devices, from smartphones to high-end portable players.
If you’re looking for something more professional, the 6.3 mm (1/4-inch) connector is often used in high-end headphones and audio equipment. Larger connectors can greatly improve durability, which is why you always find the 6.3 mm in recording studios or dedicated audiophile gear.
Connectors like XLR and 4.4 mm (Pentaconn) are somewhat less popular but still quite common, especially in balanced audio systems. These connectors can naturally reduce interference and improve left/right separation.
Finally, MMCX and 2-pin connectors are the most common IEM connection standards, and you can find them in some over-ear headphones, too.
MMCX connectors are stronger and less likely to break when connected than 2-pin connectors, but you might accidentally break them as they require more force to plug and unplug. MMCX connectors are also much more expensive than 2-pin connectors, which is why the latter type is used more often in IEMs.
Materials and technology
Certain materials are standards in high-quality cables, so if you’re looking to upgrade to a more durable cable, here’s what you should know.
Oxygen-free copper (also called OFC) is a form of copper that has fewer impurities, and therefore has excellent conductivity and a naturally warm sound. Another valid option is silver-plated copper cables, which combine the warmth of copper with clear highs.
Another cable type you’ll come across is the Litz wire. This design is a mix of individually insulated strands that help prevent oxidation. In my experience, this type of cable offers better flexibility and malleability.
Apparently, graphene-infused cables provide better signal transmission. They cost a fortune though, and I haven’t found anyone who could prove they perform better than their copper or silver counterparts.
When it comes to high build quality, you should look for braided cables, which are designed to reduce electromagnetic interference and increase durability. Similarly, some high-end cables come with Kevlar or similar reinforcement in the outer layer to make them tougher, which is great if you’re carrying your headphones around a lot.
Recommended headphone cables
Budget-friendly (under $50)
- NewFantasia replacement cables. Solidly built cables that stand the test of time.
- Kinboofi 2-pin/MMCX cables. Slightly more expensive than the NewFantasia, Kinboofi’s replacement cables are reliable and aesthetically pleasant.
Mid-range ($50-$100)
- Kinera replacement cables. In terms of comfort, style, and versatility, Kinera’s cables are top-notch. Most cables come with three termination options (4.4 mm balanced, 2.5 mm, and 3.5 mm standard) and different connectors like MMCX, 2-pin, or even custom options. Although some cables are more expensive, all their cables usually offer excellent quality at a good price.
High-end choices ($100+)
- Viking Weave Cables. If you’re looking for the best combination of durability and style, the Viking cables are my recommendation. These customizable headphone cables are thick but lightweight, with a soft and flexible structure. I could easily imagine them lasting a lifetime.
- Other similarly-priced options include the Polish manufacturer Forza Audio Works and American-made Audiophile Ninja.
Frequently asked questions
Which headphone brands have the best stock cables?
Sennheiser, Focal and Audeze notoriously provide high-quality stock cables.
Are expensive headphone cables worth the investment?
In terms of sound, the short answer is no. In terms of durability and aesthetics, definitely yes.
Is it safe to buy a used high-end headphone cable?
Yes, as long as you ensure there’s no oxidation or connector damage.
How can I properly care for and maintain my headphone cables?
Avoid twisting them too much, and store them carefully. Occasionally, use a deoxidizing cleaner to prevent corrosion.
What is the best wire material for headphone cables?
Oxygen-free copper, silver-plated copper and pure silver cables are the most common wire materials. All of them offer an excellent combination of high-quality conduction and durability.
What are the most durable headphone cables available?
Cables with reinforced sheathing usually last longer because they’re sturdier. That said, it all comes down to how you take care of them.
Can I use a longer cable without degrading audio performance?
You shouldn’t have any problems with cables shorter than 2 meters. With extremely long cables (over 5 meters), you might get some signal degradation.
What is cable microphonics, and how can it be minimized?
Microphonics is the sound that comes from cables making noise when they touch surfaces. To mitigate it, use cables that have soft insulation or a braided design. You can also use a clip to attach the cable to your shirt and choose balanced cables that provide better protection against noise.
Final thoughts
I hope this guide helped clarify some of your doubts about headphone cables.
As I said, there’s an ongoing debate as to whether high-quality cables can improve sound, and while I don’t believe they do, you shouldn’t let this stop you from upgrading your headphone cables, should you wish to. After all, durability and aesthetics of your cable are also important factors that can improve your listening experience.
