Want to experience the mobile voice quality difference between 2G, 3G, 4G and 5G?

The audio quality in mobile voice calls has evolved since the introduction of 2G mobile networks, with improvements in voice coding technologies in mobile networks and mobile phones. In 2G and 3G networks, first there was narrowband voice quality (NB, usually 13.2 kbps). Then HD voice (AMR-WB, usually 13.2 kbps) was introduced, mainly in 3G networks. With 4G, HD voice became the default voice codec in 4G smartphones. The latest voice codec “HD Voice+” (EVS, Enhanced Voice Services) will be used in 5G networks, and it can also be used in 4G.  

Listen to the audio clips below to experience what the difference is! The music clips represent music within a voice call; for example, the music in a call queue, or even music shared from a live concert you are attending.   

Note that the audio quality experience will differ between different device brands and models, as it also depends on the quality of the microphones, loudspeakers and other audio software implementations in devices. The bitrate can be set to vary between 7 kbps up to more than 24 kbps, but the most common network deployments use 13 or 24 kbps.
