AptX vs SBC – Which Codec Works Better?

When it comes to audio codecs, there are two popular contenders vying for the top spot: AptX and SBC. But which one truly reigns supreme? In this article, I will delve into the details of each codec to determine the answer.

What is AptX?

AptX is a codec that promises superior audio quality by reducing the loss of sound. It utilizes a special algorithm to achieve this feat. With AptX, you can expect clearer, more detailed audio, providing an immersive listening experience.

What is SBC?

On the other hand, SBC, or Subband Coding, is a codec employed in wireless audio devices. While it may not offer the same level of audio quality as AptX, it still manages to deliver decent sound reproduction for everyday use.

The Differences

Now, let’s dive deeper into the disparities between AptX and SBC. AptX boasts a higher bitrate, which contributes to its ability to transmit more data and ultimately deliver better sound quality. On the other hand, SBC has a lower bitrate, resulting in a compressed audio signal that sacrifices some detail.

The Verdict

So, which codec is the true champion? Well, it depends on your specific needs and preferences. If you are an audiophile seeking the utmost clarity and fidelity in your audio, AptX may be the better choice for you. However, if you are simply looking for a reliable wireless audio solution for everyday use, SBC can certainly get the job done.

In conclusion, both AptX and SBC have their strengths and weaknesses. AptX shines in the realm of audio quality, while SBC offers a practical and affordable option. Ultimately, the decision rests in your hands. Choose the codec that suits your requirements best and enjoy your audio in the way that brings you the most satisfaction.

AptX vs SBC - Which Codec Works Better?

I’m amazed at how much audio playback on smartphones has advanced over the years. Some manufacturers are even considering getting rid of the 3.5mm jack altogether. But don’t worry, there’s still a way for you to listen to music – Bluetooth codecs.

We all know that Bluetooth has a reputation for being slow when it comes to transfer speeds. However, now you can improve the rate of transfer by using a Bluetooth codec. Thanks to these codecs, you can enjoy wireless headphones and listen to your favorite music on your smartphone.

Today, let’s take a closer look at two of the most popular codecs: SBC and aptX, and figure out which one is the best.


SBC is a basic audio codec that comes included in most devices. It’s also the standard for Bluetooth devices and a requirement for all A2DP (Advanced Audio Distribution Profile) devices. It has a maximum sampling rate of 48 kHz, and its bitrates can range anywhere between 193 (for mono streams) and 328 kbps.

Now, I have to admit, this codec is quite slow. It usually has a latency of around 100 to 150 milliseconds. You might notice a slight lag when watching videos, where the audio doesn’t quite sync up perfectly with the visuals. SBC also tends to have some issues with data loss and doesn’t offer the highest audio quality. However, it’s not terrible either.



Let me tell you about aptX, a fancy piece of technology that Android phones can use. It took a while, but it’s finally compatible with Android now. It’s not exactly brand new, but Oreo, which is the eighth major release of the Android operating system, was one of the first to support it on Android devices.


Hey there! I’m here to talk to you about aptX, a cool audio codec that uses the adaptive differential pulse code modulation (ADPCM) to compress audio signals and transmit them at 352 kbps. What’s cool about ADPCM is that it can divide the audio file into four separate frequency bands, creating a better signal-to-noise ratio and making the audio quality of aptX much better than that of SBC.

But wait, there’s more! aptX also has a low latency of only 60 ms, which means the chance of audio going out of sync is greatly reduced. Say goodbye to those annoying audio delays!

Now, let’s talk about aptX’s siblings. You’ve got aptX HD, which focuses on improving sound quality. It uses a bandwidth of 576 kbps, sending higher quality data with less compression. It’s perfect for wireless headphones and doesn’t increase latency, so it’s a great choice for all you audiophiles out there.

But what if you really want to get rid of latency entirely? That’s where aptX Low Latency comes in. With a latency that stays below 40 ms, you can enjoy streaming video and audio without any fear of them going out of sync. It’s perfect for gaming or watching live streams.

Now, let’s see how you can change the Bluetooth codec on your Android smartphone:

  1. First, you need to become a developer on your Android device. To do this, go to Settings, then find the About Phone option. It might be located elsewhere, so keep an eye out!
  2. In the About menu, scroll down and find the option labeled Build Number.
  3. Tap the Build Number seven times in a row to become a developer. This unlocks additional system options.
  4. Now, you need to find Developer Options. They might be inside the System settings, or you could find them in the Accessibility menu, depending on your phone model.
  5. Look for the Networking section and find the Bluetooth Audio Codec option.
  6. Tap it to see a list of available Bluetooth audio codecs and choose the one you prefer.

So, what’s the bottom line? Well, there’s not much competition between SBC and aptX because they’re quite different. SBC has problems with data loss and high latency, and its sound quality isn’t anything special. On the other hand, aptX, made by Qualcomm, is a superior codec in every aspect. It solves many of the issues that SBC has. The Low Latency and HD versions are incredibly useful, with the latter bringing wireless headphones close to the sound quality of wired models.

But remember, the audio codec isn’t the only thing that affects audio quality. If you want to take it a step further, make sure your headphones and audio files are also of high quality.

So, which Bluetooth codec is your favorite? Or do you have another audio codec you prefer? Let me know in the comments below!
