Best Modern Buyer’s Guide

The Most Important Features to Consider

  1. Quality of Materials
    Connectivity and then with that sound quality is highly dependent on the quality of the materials. For the clearest audio, look for 100% oxygen-free copper wires and 24K gold-plated jacks. Pure aluminum and copper-clad aluminum wires may be cheaper, but OFC and regular copper wires are undoubtedly better in quality. Both silver and copper jacks offer superior conductivity but are also prone to corrosion. This is why we recommend 24K gold-plated connectors.
  2. Compatibility
    Before you purchase an auxiliary cable, you must check its compatibility with your devices. Most devices use standard 3.5mm connectors, but there are some that don’t. To avoid compatibility issues, always check the specifications of the aux cable and the devices you’ll be using it with. For instance, an aux cable with mic can’t be used with some speaker models.
  3. Durability
    For durability, consider the bend life, which indicates the number of times the aux cable can be inserted and taken out of devices before its quality deteriorates. A bend life of 10,000+ is already higher than most standard audio cables, but 15,000+ is naturally a better choice.

Aux Cable FAQs

What is an auxiliary cable?

An auxiliary cable is an audio cable used for connecting headphones, speakers, and other audio equipment to media-playing devices such as smartphones, MP3 players, and tablets. Standard cables have 3.5mm jacks on both ends. Aux cable use is a no-brainer. Just plug one end into your device and the other end into the aux input port of audio equipment. The aux cable transmits the analog signal from your device to the audio player.

What’s the ideal length for an auxiliary cable?

The ideal length for an auxiliary cable depends on where and how you’ll be using it. 3ft would be enough for connecting headphones and smartphones while on the go. For use in cars or at home, choose one that’s 4ft to 7ft long. If you’re connecting a device to your car stereo from the front seat, 4ft would suffice. If you’re likely to connect devices from the back seat, choose cables that are longer than 6ft.

Do all cars have aux input?

Not all cars have auxiliary ports. So before you buy a JBL aux cable for car use, check your car first. Older car models don’t typically include one. However, newer cars are likely to have auxiliary ports as these have become standard features for most car models today. But even if your car stereo has no aux port, you can easily add one on your own (if you’re handy with tools) or with the help of your auto mechanic.

Are gold-plated aux cords better?

There’s much debate whether gold-plated auxiliary cords are really better than copper or silver cords. Based on their inherent properties, copper and silver are actually better conductors than gold. However, both also tarnish over time. They oxidize and develop a green patina that decreases conductivity and reduces performance. On the other hand, gold doesn’t tarnish and enhances the durability of the connectors.
