There is a PureXAudio mod available due to the efforts of XDA developer ZeroInfinity which will improve the overall sound quality of the Xperia ZL. This mod is also available for the Sony Xperia Z. PureXAudio makes some tweaks – new audio effects/presets, more anti-aliasing, less noise, improved audio resolution, less clipping, very low audio latency, etc. Follow the instructions given below to install it on your Xperia ZL.
