Why Bluetooth Codec On Your Smartphone Device Needs To Be Changed Right Now

Are you searching for an alternative method to enhance the sound quality of your Bluetooth headphones to your smartphone device? If that’s the case, read on to find out how to enhance audio quality on your device.

Why Should Users Change Their Bluetooth Codec?

The Bluetooth codec for every online activity is different. For instance, users who are only interested in listening to hi-res audio will require a codec that supports superior quality results. On the other hand, users require a codec if they want consistency in their voice calls. Even though troubling internet service is to blame for this and calling the respective internet providers would be of much help, the second option is to always check if these codecs require a bit of tweaking or adjustment.

On the contrary, avid movie watchers would require codecs that facilitate the device with low latency. Although Bluetooth technology is still relatively new, there are different codecs for different online activities. That’s why users should consider altering their codec regularly as per their usage and signal strength.

Bluetooth Codecs That Are Fully Compatible With the Android Technology:

Before users learn how to change and alter the default codec on their smart device, it is important to understand the different purposes behind different codecs, so that users select the right ones:

Low Complexity Sub-Band Coding (SBC)

This is among the most common codecs and is normally supported by almost every Android device. If a device supports Advanced Audio Distribution Profile (A2DP), then chances are that it will support this codec as well.

A2DP is a set of regular stipulations for communication over Bluetooth. SBC offers ordinary audio quality as it consumes less power and is more suited for casual listening if the user is not too keen on HD surround sound kind of quality. Moreover, it saves phone battery, even though it has a higher latency than most codecs present out there. Experts’ do not consider the SBC ideal, especially if used in liaison with gaming or watching TV and movies. 

Advanced Audio Codec (AAC)

This shares multiple similarities to SBC as it utilizes more power, despite delivering mediocre audio results. Interestingly, AAC is more commonly found in Apple devices as iOS is fully optimized to take full advantage of it, yet that’s not the case for their Android counterparts.

Furthermore, as an Android user, this is not the most preferred choice available for gaming or HD listening. It should be the user’s last resort if other codecs are incompatible with earphones/headphones. Regardless, if no other options are available, users can still make do with this codec for casual listening.

LDAC Bluetooth Codec

Sony developed LDAC, which is quite similar to aptX Adaptive. Although the latter quickly adjusts with the signal strength, the former one keeps on switching between the three preset bitrates (another factor for determining the quality of audio). What’s more is that LDAC has better performance results, especially when the signal is steady and clear.

Unfortunately, on the downside, if the connection deteriorates, the constant switching between the preset bitrates is extremely annoying. For this reason, LDAC is recommended, only when the signal connection is steady and is ideal for HD audio sound. The low latency factor makes it a great choice for online gaming or streaming videos.

Low-Latency and High-Definition Audio Codec (LHDC)

The liaison between Hi-Res Wireless Audio (HWA) Union and Savitech resulted in the development of the Low-Latency and High-Definition Audio Codec (LHDC). Besides diminishing latency, this Bluetooth codec offers HD audio quality and is an excellent choice for high-res audio and video content. 

In addition, the HWA released a new type of LHDC, known as Low-Latency Audio Codec (LLAC). The best part was that the LLAC maintained high audio quality, while significantly lowering the latency of the device, making it a great choice for online gamers.

Changing Bluetooth Codec on an Android Device

Once a user has decided which codec is compatible with their earphones or headphones, is supported by their phones, and is easier to use, they can change it quite simply. To do this, simply go to settings, tap on System, then go to Developer options, which may need to be switched on first.

After that, locate the Bluetooth audio codec menu, select the preferred option and you are good to go! Users can also install new codecs on their devices. Simply go to settings, enable codec, and you are done.


Wireless tech is on its way to reaching the zenith if it wants to contest against wired technology and replace it. However, for now, getting Bluetooth codecs that synchronize with the activity and the device is crucial. Insiders still claim that not one codec is a size fit. It is still after trial and error, that allows one to find what they are truly looking for.
