Why does my aux cable sound so bad?

A true audiophile is always looking for a product that provides them with the best possible sound quality. It’s not always the case that you’ll get excellent sound quality, however. When using aux cords to connect their sound equipment.

Many people are baffled as to why their aux cable sounds so distorted and bad. So, what’s going on here? There must be a good reason or problem why the aux cable’s sound quality suddenly becomes so bad.

Typically, aux cables tend to sound so bad because of the low quality of the source, or when the sound processing unit itself is of poor quality. Generally, the dreadful analog output on your phone or music player is the source of the problem.

With an analog output line and a high-quality CD or radio source, your head unit should sound great when connected to the auxiliary line input.

There are still other reasons why aux cables may sound so bad in certain situations. It is possible that the low sound quality is caused by the usage of a poor quality cable, poor speaker system, or a low-quality output from your devices in some cases.

Consequently, if you are utilizing a cable of poor quality, there is a strong probability that you will have disruptions as well as interference.

Furthermore, if you have poor-quality speakers or if the output from your smartphone is inadequate, the aux connection may sound particularly bad.

What can you do? You must always make sure that you are using a high-quality cable in such situations. To determine whether the issue is caused by your cable or your device, you could try testing your player at various output levels.

A higher level output can be quite beneficial in combating any disturbance in the speaker system; but, you may be warping the audio outputs from your device as a result of doing so. The opposite is true as well: a lesser output can actually produce undesirable sounds.

How to Select a Reliable Auxiliary Cable

The flexibility that aux cables enable is a significant advantage that they can supply to users. Many aux cables available on the market, on the other hand, are too identical to one another and only have minor distinctions between them.

When it comes to picking aux cables, one of the most important considerations is the length, which plays a significant influence.

Everyone who uses an aux cable should purchase one that is a good length possible, allowing them to connect to their source device without causing any unintentional damage or removals.

If you are concerned about interference from noise, you can consider using thick aux cables that are highly compatible with your system rather than thin ones.

The materials that are used to construct these cables contribute to their increased longevity as well as their capacity to prevent signal interference.

So, how do you go about selecting a high-quality aux cable?

Select cables that have a connection that is plated in gold to avoid corrosion. Gold is perfect for this role, as it resists corrosion very efficiently.

If gold plating is not possible, you can always seek out those aux cables that have been treated with another metal coating, such as nickel or rhodium.

While silver coating does a great job of protecting cables from interference as well as reducing distortion and background noise, it is not as effective as gold for sound transmission.

The length of your cable can also impact its quality and performance. If you purchase a cable that is too long or too short, the connection will be worse than if you had used one that was the right size.

In general, it is best to select a cable that offers you more flexibility. This means that you should go for the one that has a good gauge, despite the size of your devices.

Another great feature of some aux cables is an in-line remote control and microphone, along with volume controls. With these options, you can use your cable to play or pause music with ease while also picking up calls without having to take your device out of your pocket.

What Else Should You Know?

Many aux cables are interchangeable, yet some do not offer the same functionality for specific devices. For instance, there are some aux cables that use a microphone with specific smartphones for voice control; if you make use of them with an incompatible device , they will not function properly.

Consider purchasing cables that have a longer life cycle as well as a larger bending radius. The bend radius helps in indicating how repeatedly the cable can be twisted without exposing any of the circuitry that is somewhere under the cable.

When it comes to durability, you will notice that braided aux cables outperform plastic aux cables on almost every level. When compared to braided, plastic ones, on the other hand, have greater flexibility.

Ways of avoiding Distortion when using an aux cable

When utilizing a long aux wire, high possibility of experiencing audio distortion or interference. So, what is the best way to get around this problem?

Begin by purchasing thicker aux cables to use as a starting point. This is because such cables are more resistant to interference. Alternatively, you can purchase cables that are constructed of high-quality copper components.

Furthermore, based on whether your equipment is compatible with XLR or balanced connectors, you can buy a set of connections. These cables have the ability to extend to around 100 feet (30.48 meters) without deformation.

An additional option is to acquire a power amplifier, which increases the strength of input, including one that comes via an aux connector.

Another option is to alter the output impedance of your pre-output amp’s circuitry. In order to perform this successfully, you must play with the audio until you find a tone that you appreciate.


Many factors contribute to the poor sound quality of an aux connection, including poor quality cables, connectivity issues, and issues with your output device. In either case, there are a variety of approaches that can be employed to keep such issues to a minimum.
