Choosing the Right Aux Cable

There are a number of different buying factors that must be considered when buying an auxiliary cable for your car. If you’ve never bought an auxiliary cable before, then these buying factors will allow you to understand which one will meet your requirements. Auxiliary cables for the most part perform a simple function, but there are subtle differences between cables that should be understood before purchase.

  • Gold jack: mid and high-end products will contain a gold plated audio jack, and this is an important feature to have. That’s because gold is by far one of the best materials for transmitting an electrical impulse. This allows you to experience the best possible sound as the disturbance will be non-existent. The layer of gold is typically very thin, which means the price will not be significantly higher.
  • Materials: the quality of the material used should also be considered. Pretty much all wires use copper, but the quality of the copper might differ from one wire to another. It’s better to look for a cable with a better copper compound so that you’re able to enjoy higher quality audio reproduction.
  • Get the best cord, not the best deal: it’s important to consider the quality of the auxiliary cable as opposed to just paying attention to the price. To enjoy audio for the long term a quality cable is the way to go as opposed to looking to cut corners with the price.
  • Compatibility: the majority of devices are setup to use the 3.5mm standard, but that isn’t always the case. Therefore, you need to check with your specific equipment to see what you need to purchase in order to ensure compatibility doesn’t become a problem.
  • Bend life: the bend life is the number of times that the auxiliary cable can be inserted and taken out before signs of wear and tear begin to take place. Ideally this value should be above 10,000, but 15,000 is even better.
