What’s the Difference Between Toslink and AUX?

toslink vs aux

If you’re shopping for a new audio receiver or soundbar, you might notice that some units have an aux input while others have a Toslink input (or both). But what’s the difference between the two, and which one should you use? Let’s take a closer look.


Toslink is an optical fiber cable that is commonly used to connect home theater systems and other digital audio devices. One of the benefits of Toslink is that it is not susceptible to electromagnetic interference (EMI), which can degrade the quality of your audio signal. Another benefit is that Toslink cables can be much longer than Aux cables without losing any sound quality—up to about 50 feet.


Auxiliary (Aux)

An Aux cable is a standard 3.5mm audio cable that is used to connect headphones and other audio devices. While Aux cables are not as durable as Toslink cables, they are less expensive and easier to find. One of the main benefits of Aux cables is that they can be used with any device that has a standard 3.5mm headphone jack—which is just about every device these days.

Toslink vs AUX: Which One Should You Use?

Toslink is a type of optical audio cable that uses fiber optics to transmit sound from your audio source to your speakers. Toslink is capable of transmitting a Dolby Digital 5.1 or 7.1 surround sound signal, making it ideal for home theater systems. AUX, on the other hand, is a type of analog audio cable that uses copper wires to transmit sound. AUX cables are typically used to connect portable music players, like iPods, to car stereos.

So, which one should you use? The answer, as with most things in life, is it depends. If you are looking for the highest quality audio experience possible, then Toslink is the way to go. However, if you are on a budget or just need a quick way to connect your devices, then Aux is the way to go.

If you’re looking to set up a home theater system, then Toslink is the way to go. However, if you just want to connect your portable music player to your car stereo, then AUX is the better option.

The Pros and Cons of Using Toslink vs Aux Cables

If you’re looking for the best possible audio quality, it’s important to choose the right cable. we’ll be comparing two of the most popular options on the market: Toslink and aux cables. Keep reading to learn more about the pros and cons of each type of cable.

Toslink Cable Pros:

  1. Excellent sound quality – Toslink cables are capable of providing crystal-clear sound quality that is virtually indistinguishable from the original source material.
  2. Low cost – Toslink cables are relatively inexpensive, especially when compared to other types of high-end audio cables.
  3. Ease of use – Toslink cables are extremely easy to use and require no special adapters or converters. simply plug them into the appropriate ports on your devices and you’re good to go.

Toslink Cable Cons:

  1. Can’t Be Curved – The transmission on the optical fiber requires repeating at distance intervals. The fibers can be broken or have transmission losses when wrapped around curves of only a few centimeters radius.
  2. Difficult to Splice – The optical fibers are difficult to splice, and there is a loss of light in the fiber due to scattering. They have a limited physical arc of cables. If you bend them too much, they will break.
  3. Limited compatibility – Toslink cables only work with a limited number of devices; they will not work with 3.5mm aux input ports, for example.

Aux Cable Pros:

  1. Versatile – Aux cables can be used with a wide variety of devices, including both computers and stereos.
  2. Affordable – Aux cables are very affordable and can be found for as little as a few dollars at your local electronics store.
  3. Solid construction – The connectors on aux cables are made of metal, which makes them much more durable than the plastic connectors found on Toslink cables.

Aux Cable Cons:

  1. Potential for static – Due to their design, aux cables can sometimes produce a faint static noise when they’re first connected.
  2. Requires adapter for some devices – While most newer computers and stereos have aux input ports, some older models do not. As a result, you may need to purchase an adapter in order to use an aux cable with those types of devices..
  3. limited sound quality potential – While aux cables can provide good sound quality, they cannot match the fidelity of higher-end options like optical or HDMI cables. This means that if you’re looking for the absolute best possible sound quality from your system, an aux cable may not be the right choice for you.
  4. short lifespan – Due to their exposed wires, aux cables have a shorter lifespan than many other types of audio cables. This means that you may need to replace your aux cable more often than you would need to replace other types of cables.

When it comes down to it, there is no clear winner in the Toslink vs aux debate; it ultimately depends on your individual needs and preferences. If you’re looking for the best possible sound quality, then Toslink is probably the way to go. However, if you’re looking for a more versatile and affordable option, then an auxiliary cable might be a better choice. Whatever you decide, just make sure that you take into account all of the pros and cons before making your final decision!

In summation, Toslink is better for home theater systems while AUX is better for connecting portable music players to car stereos (or other similar applications). So, when shopping for a new audio receiver or soundbar, be sure to check whether it has a Toslink input or an AUX input (or both).
