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.
The Monoprice Premium S/PDIF Digital Optical Audio Cable offers all the essential features you need at a competitive price and delivers excellent performance. It comes with full-sized male Digital Optical Audio connectors on both ends, which are equipped with gold-plated ferrules to reduce corrosion. The precision-polished fiber tips ensure optimal signal transfer, while the mesh metal jackets provide protection against potential damage.
With an 8mm outside diameter, the cable is sturdy, but this thickness means it may not fit into some devices with recessed ports. This is particularly relevant for the slimmer Xbox 360 model, which could pose a challenge for some users. It’s a good idea to check the port you plan to use to determine if this could be an issue for you.
The Monoprice S/PDIF Digital Optical Audio Cable is an excellent budget-friendly option. The 6-foot length is suitable for most people's needs, and it features full-size TOSLINK connectors on both ends. The cable is designed with molded heads and strain-relief boots, along with gold-plated ferrules, similar to those found on more expensive cables.
While the cable has precision-polished fiber tips, it does come with plastic tip protectors on each end, which helps keep the price down. However, this shouldn't be a significant concern for most users. Overall, the Monoprice S/PDIF Digital Optical Audio Cable performs well for its price and has received excellent reviews.
Monster has built a strong reputation in recent years for producing premium cables that are designed for durability. While they are more expensive than many competitors, the Monster M-Series 1000 Fiber Optical Audio Cable is an excellent choice if you prioritize longevity. Its diameter is larger than most due to the Duraflex protective jacket and sturdy metal housing surrounding the cable.
Despite this enhanced durability, the cable remains easy to route and install, featuring corrosion-resistant, gold-plated connectors that ensure optimal performance. Engineered to withstand more twisting and manipulation than average, the Monster M-Series 1000 Fiber Optical Audio Cable is a wise long-term investment for those looking for reliability in their audio solutions.
The Amazon Basics Toslink Digital Optical Audio Cable is a versatile and reliable choice for connecting your audio-visual equipment. Known for their dependability, Amazon Basics products usually meet expectations, and this cable is no exception.
It is lightweight and flexible, yet durable, making it suitable for a variety of AV connections. The cable features corrosion-resistant gold-plated connectors along with buffer tubing, which ensures a secure fit. However, some reviewers have noted that its diameter may not fit every port perfectly. Overall, the Amazon Basics Toslink Digital Optical Audio Cable is a highly reliable option for your audio needs.
It's convenient to quickly identify cables at the back of your TV. With the BlueRigger Optical Audio Toslink Cable, the blue ends make it easy to spot the optical cable. Additionally, this cable is a generous 15 feet long and features 24K gold-plated connectors.
In addition to these important features, the BlueRigger Optical Audio Toslink Cable has a lightweight and flexible PVC jacket designed for long-lasting use. It also comes with removable rubber tips for added protection when the cable is not in use. The snug fit ensures that you won't have to worry about the cable coming loose.
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.
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.
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.
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.
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.

Audio-Technica, a brand well known for making some of the best studio and professional headphones on the market, has just come out with the ATH-AWX7000, which the company itself claims to be its "finest headphones ever."

The earcups are made from Kiso cypress, a prized wood historically used for Shinto shrines and Buddhist temples. Each housing is finished by hand with traditional Echizen lacquer, which brings out the grain and is expected to darken over time. The frame and sliders are finished in a deep navy kachi-iro shade traditionally associated with samurai.
