Best 3.5 mm Cable – Making the Perfect Audio Cable Choice in 2023


A 3.5mm audio cable (aux cables) connects an audio input device to your car speakers, such as an MP3 player or smartphone. 

They are available in several lengths depending on your requirements and preferences.

Today’s article focuses on the best 3.5mm cable and the factors you can consider when buying one.

How to Pick the Best 3.5mm Audio Cable?

Here are a few criteria to find a preferable 3.5mm audio cable.

Connector quality

Different materials usually contribute to a connector’s quality, for instance;

  • Gold-plated contacts are corrosion-resistant. However, you don’t necessarily need them. 
  • Silver contacts are cheaper and more conductive compared to gold contacts. 
  • The best connectors are the step-down types with a feature that leaves room for fitting into a smartphone without bursting. 
  • Lastly, there are audio cables with hard metal outer shells that are reliable and durable.

Cable length

Generally, long audio cables are more susceptible to tangling, interference, and signal deterioration. Thus, opt for the minimum possible length for your particular application. For example, a 2-to-6ft audio cable should suit your car’s needs.


Heavier-gauge conductors often enhance the total cable capacitance, quantified in pF/ft (picofarads per foot).

Higher capacitance can alter the voltage signal conveyed via the conductors, thus distorting the audio regenerated by headphones (both closed- and open-back), monitors, or speakers.

Furthermore, capacitance reduces if the insulation is thick.

Jacket and Insulation

The material that covers the bare copper conductor within a cable is an insulator, and examples include nylon, polyethylene, and PVC. 

Contrarily, a jacket is a material that covers the entirety of the audio cable (conductor, insulator, shielding).

Undeniably, PVC is an excellent option for a long-lasting and dependable jacket material.

Also, audio cables with Nylon braids as jackets are more robust.


Conductors send audio transmissions to speakers from audio devices.

  • Copper metal is by far the best in cable conductivity.
  • Oxygen-free copper (OFC) does not improve conductivity much. Despite the expense, some audiophiles will still want it.
  • Heavy-gauge conductors are more robust, though they increase capacitance and are less flexible.

Manufacturers usually place cotton between shields and conductors to prevent static discharge interference and friction. 

Shielding layer

Audio cable shielding is a woven copper spiral or mat that manufacturers wrap around the audio cable’s primary conductors. Shielding blocks electromagnetic interference from radiation.

The barrier prevents outside pops and noise from interrupting your songs.

Generally, aluminum laminate foil, tin-plated copper, and pure copper make up the most used shielding materials.

Denser shielding weaves reject more RF radiation and noise even though manufacturing is costly and takes longer.
