Bluetooth Audio: how to know if your mobile phone is compatible

Since its launch more than two decades ago, Bluetooth hasn’t stopped evolving. This technology is currently in its version 6.0 and has gained many improvements in performance, connection and energy efficiency.

Well, one of the latest news of this wireless technology is calling Bluetooth LE Audio. It is a new standard that guarantees higher quality audio transmission and lower energy consumption.

Do you want to know more? Well, then let’s explain why Bluetooth Audio is the best way to listen to music with your mobile and wireless headphones. Furthermore, we tell you How to know if your devices are compatible with Bluetooth LE Audio.

What is Bluetooth to Audio

Bluetooth audio is a More energy efficient music transmission standard, with better audio quality And this one also has further improvements. This was released in 2022 and is available from Bluetooth 5.2 and its later versions: 5.3, 5.4 and 6.0.

It’s important Do not confuse with Bluetooth Lea standard that was launched in 2013 and which, although it is also designed to consume less power, only works with tasks that require a short and small amount of data (not like audio transmission). Indeed, one might say Bluetooth audio is the musical evolution of Bluetooth Le A decade ago.

How does this standard achieve energy and fidelity benefits? Well, its main attribute is The introduction of the new LC3 codec. This codec compresses audio transmission, resulting in less bandwidth (345 to 160 kbps) and has a lower bit rate (32 to 16 bits) than SBC COD which traditionally uses the Bluetooth Classic audio standard.

This change in compression makes Bluetooth audio transmission consumes less power. And although you might think that fidelity is lost in transmission, the Bluetooth Sig (Special Interest Group) He conducted a study and concluded that for listeners The audio quality is superior with Bluetooth LE Audio.

Furthermore, we must mention that Bluetooth Audio offers other improvements such as a Less latency, greater connection stability (thanks to the multi-stream technology that connects to both headphones) and it is With Auracast compatiblea solution that allows you to connect an unlimited amount of headphones to a single audio source and which we will talk about in depth in this article.

What is Bluetooth to Audio

Thanks to all the features that we have already mentioned above about standard Bluetooth audio, these would be the advantages it offers when listening to music:

• Longer mobile battery life and headphones Thanks to the improvement in energy efficiency provided by the LC3 CODEC.
• Better audio quality Thanks to optimized compression fidelity, according to the study by Bluetooth Sig (Special Interest Group).
• Greater connection stability Thanks to the multi-stream technology that allows the mobile to maintain a connection with multiple devices at the same time (it will connect to both headphones at the same time and not just one to send the transmission to the other with the delay and synchronization problems that this supposes).
• The possibility of Enjoy shared and huge audio experiences Thanks to the Atacast technology with which, for example, at a party many people can connect their headphones to the same music source to listen simultaneously and synchronized.
• Less latency in audio transmissionwhich offers competitive advantages in video games and also improves audio synchronization when watching a movie or series using headphones.

It is important to remember that, to enjoy these benefits, both the device that will be the source of the audio (mobile, tablet, player, etc.) and the receiver (headphones, speakers, etc.) must both be compatible with Bluetooth.

How to tell if your cell phone has Bluetooth audio

Finally, you should know that although audio is available from Bluetooth 5.2, this does not mean that it is pre-installed in these versions. It is an additional feature of Bluetooth and not all devices usually carry it. In fact, it is more common for devices to not be compatible with this very recent standard.

To find out if your mobile phone is compatible with Bluetooth, you can search on the Internet to see if the manufacturer specifies it in its characteristics. However, one trick we recommend is Use the Devcheck app to see if your cell phone has Bluetooth audio… How is it made? Well, as follows:

• Go to playstore and Download Devcheck on your mobile phone (we leave the link).
• At the end of the installation, Open the app Devcheck.
• Go to the section Hardware And go find the section Bluetooth.
• Here you have to look Audio support. If you have a green check (✔) it means your phone is compatible. If you have gray (x), it means that your cell phone does not have Bluetooth in audio.
