How to Boost Bluetooth Audio Quality on Android Device
With the disappearance of headphone jacks from the majority of premium smartphones, Bluetooth earphones have taken the spotlight. Despite notable advancements in Bluetooth technology, including support for various audio codecs such as A2DP, the disparity in sound quality between wired and wireless earphones of similar price points persists. If you find that your Bluetooth earphones aren't delivering the audio quality you desire, there's a workaround to enhance their performance.
Android smartphones offer the flexibility to adjust the Bluetooth codec based on the earphones in use, maximising their potential and improving sound output. Before delving into the steps, it's crucial to grasp the concept of codecs and how they function. Bluetooth earphones use different codecs to compress analog audio for transmission and decompress it upon receipt. Common codecs like SBC are universally supported, while more advanced options like aptX (by Qualcomm) and LDAC (by Sony) offer superior audio quality by transmitting large data packets.
However, it's essential to ensure that both the smartphone and the earphones support the chosen codec to fully capitalise on its benefits. Codec compatibility varies by device, so it's advisable to consult the earphones' support documentation or packaging to determine which codecs are supported. While budget-friendly Bluetooth earphones typically support basic codecs like SBC or AAC, higher-end options may offer support for advanced codecs like LDAC or aptX.
In many cases, if the earphones support Qualcomm's aptX, the device will automatically switch to this codec. However, for codecs such as LDAC or AAC, manual selection may be required to optimise audio performance.
