Soundbar HDMI vs. Optical: Which One is Better and Why?

Many people use their family room for all kinds of recreation. They stream the latest show on Netflix and watch Blu-ray movies. They also play Call of Duty battles with their PS4 or play PUBG on their PCs. Their sound system gets a lot of use. So, they need a better sound system for their home theater system.

While building my home theater system, I invested in a soundbar. So, while researching which soundbar would be best for my busy home theater system, It came with an HDMI and an Optical soundbar. While buying, you need to choose one between these two soundbars. So, which one should you choose? Which one would be the best one for your home theater system? What are the differences between these two soundbars?

Both the soundbars provide quality sound. HDMI soundbars come with audio and video usage, making them a nice option when used in conjunction with your TV, Blu-ray player, etc. Let’s found out which one would be the best one for you.

What Is Soundbar?

RIF6 Soundbar

Many of you don’t know what a soundbar is. A soundbar is a centrally located speaker system that doesn’t take too much space and provides high-quality sound. Soundbars are often renowned for their high-quality sound.

You can use a soundbar as a part of a full surround sound system or as a stand-alone speaker. When you use it as a stand-alone, you will get high-quality sound without taking up much space. But when you use it as a full surround sound system, it will take more space than a stand-alone. You can easily set them up.

HDMI (ARC) vs. Optical – What is the Difference?

Now, let’s come to the differences. Though the differences between these two soundbars are subtle, they are worth considering. Let’s discuss them in detail.

HDMI Soundbars

HDMI

The full meaning of HDMI is “High-Definition Multimedia Interface.” Nowadays, this is one of the most common types of cable. They provide quality sound and video quality. They also provide reliable and consistent video and sound quality.

You can easily use them because these types of cables relay both video and audio signals between devices. It will take fewer cables to connect your devices.

You Must Use HDMI ARC to Connect from TV to Soundbar

Connect your TV to your soundbar with an HDMI cable. You will need to use the TV’s HDMI ARC input. This sends the sound from the TV to the soundbar. You can also use an HDMI ARC input as a regular HDMI input, but it doubles as an audio output too.

Optical Soundbars

Optical

An optical cable can produce consistent and reliable sound. Many have said that Digital Optical cables provide better sound than an HDMI cable. If you have a home theater system, you would like to buy the optical cables for the quality sound. Optical cables only relay audio, not video. So, if you want a relay video, then you will need to buy an additional cable.

Comparing the Specs

When you come to choose between these two soundbars, you need to consider some factors. It would be best if you gave priority to your input options and the placement of your soundbar. Let’s check it out.

Input Options

When it comes to input options, you need to consider what types of inputs and ports your devices have. Many devices will give a permit to use HDMI cables. If your device doesn’t allow the use of HDMI cables, you need to make sure you have the right video cables needed to relay pictures between your device and TV.

Many people buy except a proper connection type to find out their device does not allow for that cable. How surprising it is!

The Bottom Line: If you are looking only to relay sound, A Digital Optical is the best choice for you. A Digital Optical provides the same sound quality as an HDMI does. If you want to watch Blu-ray, Netflix series, game consoles, you should purchase an HDMI cable. 

Soundbar Placement

Now, you need to place your soundbar perfectly. If you want to put it behind your TV, it is going to be a bad decision. Why do you use a soundbar? Usually, you use a soundbar to minimize the footprint of your home theater system. 

A soundbar provides you a minimalistic approach to sound. An HDMI cable offers you this minimalistic approach with only one cable to relay sound and video quality. But using a Digital Optical cable will mean you need more wires to relay video quality.  

The Bottom Line: An HDMI won’t take much space. It keeps your space wire requirement minimum. But a Digital Optical cable needs much space and wire requirement if you want to relay video quality. If you don’t like the wiring mess, you wouldn’t like to go with a Digital Optical.

Question

What type of cable do I need for Dolby Digital sound?

Both Optical and HDMI cables can relay Dolby Digital sound between your source and receiver device. So, in that case, you don’t compare these two soundbars. But if you want to play DTS-HD caliber audio, Dolby TrueHD, both the soundbars won’t support those. An HDMI has the capability to do those, but an Optical hasn’t.
