There has been an ongoing debate between which interface is superior: USB or Optical. I have come to a conclusion that the answer is neither, but rather just different, and there are pros and cons for both interfaces.
Optical cables are the most common type of cable that can be found in homes today. They use light waves to transmit data, which is why they are faster than coaxial cables. Coaxial cables also transmit data, but they do so using a different method.

There are a few distinct alternatives accessible when it comes to data transmission. Optical media, which employs lasers to read and write data, is one of the most prevalent. USB, which stands for Universal Serial Bus, is another possibility. Because of its speed and ease, USB is a more recent technology that is gaining favor.
Audio: Optical vs. USB
The fundamental distinction between optical and USB audio interfaces is that optical interfaces transfer digital audio data using light, while USB interfaces utilize electrical wires. With high-end speakers or headphones, however, there is no discernible difference between USB and optical.
Optical interfaces, in any event, are less prone to interference than USB connections. As a consequence, optical connectors generate higher-quality signals than USB interfaces.
There are, however, a few exceptions to this rule. Some high-end USB audio interfaces, for example, may deliver a higher-quality signal than an optical interface of comparable price.
In addition, to improve signal quality, certain USB audio interfaces include electrical and optical components.
Sound Quality: USB vs. Optical
In principle, there is no difference in sound quality between USB and optical connections. USB connections are notorious for their poor sound quality, but optical connections provide crystal-clear, crisp sound that no other connection type can equal.
This is due to the fact that optical connections carry data using light rather than electricity, while USB connections utilize electricity. Noise may be introduced into the signal by electricity, lowering the sound quality.
Optical connections are also impervious to electrical interference, making them perfect for high-resolution audio playback. If you want the finest sound quality from your audio equipment, utilize optical connections wherever feasible.
High-quality speakers and headphones, on the other hand, can readily filter out this distracting noise. With these high-quality devices, you won’t be able to tell the difference between USB and optical in most circumstances.
USB DAC vs. optical DAC
Because of its increased resolution and bit depth, an optical DAC usually produces superior sound quality.
An optical connection, on the other hand, may be more picky than a USB connection, and it may not work with all devices.
When it comes to compatibility, USB DACs are more forgiving, and they’re also less expensive than their optical counterparts. They normally do not, however, provide as excellent a sound quality.
Optical vs. Coax vs. USB
Coax cables are ideal for long-distance data transmission. They also have a high bandwidth capacity, which means they can handle a large amount of data at the same time. They are, however, both costly and complex to install.
Optical connections are ideal for swiftly moving huge volumes of data. They have a minimal latency and are not affected by electromagnetic fields. They are, however, more costly than other solutions and may not last as long. Because of their versatility and affordability, USB cables are a popular alternative for data transmission.
They have a high bandwidth capacity and may be utilized for both short and long distances. They are, however, prone to interference and may be slower than other solutions. When deciding the sort of cable to utilize, it’s crucial to think about the project’s unique requirements.
Large-scale projects with lengthy transmission lengths benefit from coax cables, whereas high-speed data transport benefits from optical connections. Because USB cables are inexpensive and adaptable, they are a fantastic option for general usage. In the end, the best option will be determined by the specific project needs.
Optical Soundbar vs. USB Soundbar
It might be difficult to decide whether to connect a soundbar through optical or USB. What you need to know is as follows:
- A USB connection delivers audio impulses as digital data, but an optical connection conveys them as light.
- Because it transmits a purer signal with less noise, an optical connection is commonly seen to be preferable.
Not all soundbars, however, include an optical input. You may utilize a USB connection instead if your soundbar doesn’t have one; just make sure your device has one.
Audio Quality: USB vs. SPDIF
It’s tough to compare the audio quality of USB and SPDIF. It is highly dependent on how each system is implemented as well as the quality of the components employed. However, in terms of audio quality, USB is generally believed to be inferior than SPDIF.
The fact that USB is a shared bus system is one of the key reasons behind this. This implies that data from several devices is sent over the same cable at the same time. Interference and poor sound quality might result as a result of this.
SPDIF, on the other hand, sends data one bit at a time and is unaffected by interference. Furthermore, USB audio is often restricted to 16-bit/48-kHz, while SPDIF may handle up to 24-bit/192-kHz.
The quality of the DAC (Digital to Analog Converter) has a significant impact on the performance of USB audio, hence this must be considered when comparing systems.
While some people favor SPDIF for its higher sound quality, others prefer USB because it is more practical and enables ports to be shared. Both systems may provide excellent results in home audio applications, depending on an individual’s tastes.
PS4: USB vs. Optical Audio
USB audio is unquestionably the more convenient alternative. It’s simple to use; just attach your headphones or speakers to the PS4’s USB port and you’re ready to go.
Optical audio, on the other hand, needs a little more time and effort. To receive sound output, connect an optical connection between the PS4 and your audio device, and then select the parameters.
USB vs. Schiit SPDIF
SPDIF and USB are the two choices available from Schiit Audio.
SPDIF is an older technology that sends audio data from your computer to a receiver or amplifier through a digital signal.
It is a flexible solution since it may be utilized with both analog and digital connections. However, since SPDIF is susceptible to interference, it may not be the greatest solution for noisy locations.
USB is a newer technology that uses light pulses to deliver audio data. Because there is less danger of interference, it is more dependable than SPDIF, although it cannot be utilized with analog connections.
Additionally, USB needs a computer or laptop to transmit and receive data, so check sure your computer has USB ports before purchasing.
Schiit Audio devices have both SPDIF and USB functionality (except for the Yggdrasil headphone amp). So, if you want a single box that does everything effectively and has no drawbacks, Schiit is a great option.
It is entirely dependent on your requirements. Optical is the way to go if you require a high-quality connection with no interference and don’t mind paying a little more. If you just require a basic connection and are on a tight budget, USB will do.

Frequently Asked Questions
Is optical or USB better sound?
A: There is no way to know what type of audio card you have, so the answer isnt really black and white. If your sound cards are USB or optical then they will both be compatible with a common 3.5mm jack on most headphones/speakers which means that it should work fine. But if one of them requires an adapter, such as a Lightning connector for iOS devices, then you might run into some problems connecting them properly
Is Optical better than HDMI?
A: The answer to this question is not as simple as it seems; both are technically better in their own ways.
Do optical audio cables really make a difference?
A: Yes, optical audio cables can really make a difference in the quality of sound you get from your device. They are able to transmit information to and from devices at much higher speeds than standard Micro-USB or USB C ports.
