Optical audio cables, also known as TOSLINK cables, are essential for transmitting audio signals between devices in your home cinema setup. They are particularly useful for connecting older sound systems or linking devices like high-quality soundbars to your TV. However, the prices of optical audio cables can vary significantly, which can make it challenging to choose the right one.

These cables utilize fiber optic technology to transmit digital audio signals, setting them apart from many other types of audio cables. Before purchasing an optical audio cable, ensure your device has an optical audio port and decide whether you prefer to use HDMI for connections instead. Below, we have highlighted some of the best optical audio cables available today and explained how we made our selections to help you make an informed decision.

Pros
  • Ideal for awkward angle placement
  • Braided
Cons
  • A little short
Specification:
Length 5ft
Outside diameter 10mm

Sometimes, a standard cable just won’t do, especially when a 90-degree angle is more practical for many users. This is particularly true when wall-mounting a TV or dealing with limited space. The EMK 90-Degree Toslink Optical Cable is designed specifically for such situations.

It features a robust braided nylon mesh jacket and heavy-duty construction, making it durable enough to handle awkward placements. The angled connector adds further convenience for connecting to devices.

While it is slightly shorter than average at 5 feet long, it connects easily to all compatible devices. Although there have been occasional reports about its sound quality not being as high-end as some competitors, this difference is likely to be negligible for most users.

How we chose these optical audio cables

Choosing the right optical cable can be overwhelming due to the sheer number of options available—thousands, in fact. Where should you start? To help simplify the process, we’ve highlighted some key points. However, it’s essential to understand the factors we considered before making our recommendations. Here’s what you need to know.

Think about the fit you need

While it may seem like everyone needs a highly durable cable, that’s not always the case. If you simply plan to place a cable behind the TV and leave it there, any solution will work. However, if you intend to feed the cable into a wall or a similar space, it’s best to invest in something more durable since you don’t want to have to replace it frequently. Additionally, consider whether an angled cable might better suit your needs compared to a traditional straight cable.

Pricier isn’t always better

Similar to HDMI cables, it’s possible to spend a significant amount of money on a single cable. However, the differences in quality are often not as substantial as one might believe. While spending more can provide peace of mind, most people will be perfectly satisfied with a more affordable option and are unlikely to notice any difference in performance.

How long do you need it to be?

Most audio cables typically measure around 6 feet in length, with some being only 5 feet long. The ideal length for your cable depends on your specific setup, and you may find that a shorter cable simplifies cable management. However, you might also need a longer cable, such as a 15-foot option. To determine the appropriate length, measure the space you’re working with and aim for a cable that is slightly longer than your requirements. This will provide you with extra flexibility.
