How to change Bluetooth codec on your android phone?

Before following the steps it is important to understand what is a codec and how it works. Codecs are a program that compresses the analog audio and transmits it to the earphones via Bluetooth and then earphones decompress it back to the audio signal.

There are various Bluetooth codecs used by wireless earphones such as SBC, AAC, LDAC, etc. The most commonly used is the SBC (Sub Band Codec) which is a universal codec and all the Bluetooth audio devices support this.

The operating system of your android phone usually chooses the SBC codec by default, but in some cases, you can change it to a better codec such as AAC or LDAC. If you are using a Qualcomm chipset-powered smartphone with a headphone that supports the aptX or aptX HD codecs then the smartphone will automatically select the better codec.

What codec should I choose?

A lot of headphones support the AAC codec apart from the SBC but if your headphones have SBC in default mode then you should manually switch to AAC mode since AAC is a more advanced codec than SBC. For high-end headphones, switching to Qualcomm aptX or Sony LDAC will improve the sound quality by a fair amount.

To change Bluetooth codec settings in android phone go to:

  • Head to Settings and search for About.
  • Now scroll down to Build number and tap on it 7 times until you see a message You are a developer.
  • Now connect the earphones to your mobile phone and head back to the Settings page.
  • Now locate Developer options and search for Bluetooth Audio Codec option.
  • Now choose the codec option the earphones suggest.
  • Now restart the phones and enjoy the enhanced audio quality.

In-built sound quality enhancer

You can easily enhance the sound quality of your earphones just by selecting a few options in the settings. Not all android phones have this feature, these are available in a few of the phones such as Xiaomi, Samsung, Sony, etc.

For Xiaomi devices:

  • First, insert the earphone in your mobile phone then go to Settings.
  • Now scroll down to Additional settings and again scroll down to Headphones & audio effects.
  • Now you can enhance the audio quality by selecting the Mi Sound Enhancer option.
  • Inside the Equaliser option, you can select from various music styles such as Jazz, Rock, Pop, Classical, etc.

You can also select the type of earphones or headphones you are selecting to get the optimized sound.

For Samsung devices plug in the earphones and go to:

  • Settings and tap Sounds and vibration.
  • Now go to Sound quality and effects. You should have a series of options to enhance your audio experience.

What if you don’t have an in-built audio quality enhancer? The next method will solve your problem.

Download an Equalizer app

Check your speakers

Nowadays a lot of mobile phones have dual speakers grills and most of the time only one of them is working. If your speaker is blocked then the sound quality will obviously be of low quality.

mobile speakers

So play some songs and cover various holes until you know from exactly where the audio is coming from. Once you know where your speakers are (front-facing, bottom or back) then you can understand how to position the smartphone so that it will produce better sound.

Make sure you don’t block the bottom part of your mobile phone (in case the speaker is bottom-mounted) while holding your smartphone.

Check if your phone case is blocking the speaker

Though phone cases protect your smartphone from any physical damages it will also sometimes affect the sound quality of your phone.

The vibrations coming from your phone will be absorbed by the plastic or rubber and manufacturers don’t think about this when making the phone cases (since rubber and plastic can protect your phone better than other materials).

So before buying any phone case next time make sure the phone case doesn’t block the audio jack, microphone or speaker.
