Used to transmit audio signals between devices, optical audio cables (also known as TOSLINK cables) are an important addition to your home cinema setup when connecting older sound systems or linking devices like one of the best soundbars to your TV.

Pros Cons
Well priced Doesn’t fit Xbox 360 Slim model and some other recessed ports
Good length

Offering all the essentials you could need, the Monoprice Premium S/PDIF Digital Optical Audio Cable is well-priced and highly effective. It has full-sized male Digital Optical Audio connectors at each end with gold-plated ferrule helping to cut back on corrosion. Precision polished fiber tips ensure maximum signal transfer while there are mesh metal jackets that protect the cable from any potential damage.

An 8mm outside diameter ensures chunkiness but also means that certain devices with recessed ports mean the Monoprice Premium S/PDIF Digital Optical Audio Cable won’t fit. That includes the slimmer Xbox 360 model which could affect some users. Check out the port you need to use to consider if this could become a problem for you.

There are precision polished fiber tips too but plastic tip protectors on each end are where corners are being cut to keep prices down. It’s no great hardship though. For most people though, this won’t be an issue and the Monoprice S/PDIF Digital Optical Audio Cable works very well for the price, garnering some excellent reviews.

Pros Cons
Ideal for awkward angle placement Little short
Braided cable

How we chose these optical audio cables

Finding the right optical cable for you can feel overwhelming because there are literally thousands of options around. Where do you even begin? That’s why we’ve narrowed things down to some highlights but it’s important to know what factors we considered before recommending anything. Here’s what you need to know.

Think about the fit you need

While it might seem like everyone needs a highly durable cable, that’s not actually always the case. If you simply plan on placing a cable behind the TV and leaving it, you’re good to go with any solution. However, if you want to feed the cable into a wall or similar, you really don’t want to have to replace it often. That’s why it’s important to invest in something highly durable at a time like this. Similarly, think about if an angled cable would suit your needs more than a traditional length of cable.

Pricier isn’t always better

Like HDMI cables, you can spend a huge sum of money on one cable. In reality, the difference isn’t as huge as you might think. While you might appreciate the peace of mind of spending a lot, the vast majority of people will be perfectly happy with something that’s a more affordable price, and they won’t notice a difference.

How long do you need it to be?

Most audio cables are about 6 feet long with some only 5 feet long. Only you know how much length you actually need. Depending on your setup, you might actually want it to be shorter because it’ll make cable management much simpler. Alternatively, you might need something much longer such as a 15-foot cable. Measure the space involved and aim to go slightly longer than you need to ensure you have plenty of flexibility.

The 6 best OLED TVs for 2024
A toucan shown on an LG G3.

Chances are, if you've been on the search for a new TV you've come across a wall of big, beautiful options at your local Best Buy slapped with the acronym "OLED" on their labels. If so, you've got a good eye, because OLED TVs are the cream of the crop when it comes to picture-perfect panels.

But what is an OLED and why should you want one? The main idea behind OLED (which stands for Organic Light Emitting Diodes) engineering is the complete absence of traditional LED backlighting, like you’d find on today’s leading QLED sets. Instead, the individual pixels on an OLED screen are completely self-emissive, meaning that they produce their own light instead of being back-lit like in TVs such as QLEDs, OLEDs main rival. This also means that each pixel has the ability to be completely turned off, producing pure, inky black levels that deliver incredible contrast, and stunning images.
