ITU-T P.383 PDF

This Recommendation specifies technical requirements and test methods for wired or wireless headsets and corresponding digital interfaces.

The aim of this Recommendation is to ensure adequate user experience when wired or wireless digital headsets are connected over the digital headset interface with digital terminals:

Terminals in the context of this Recommendation may be mobile terminals, portable players, information and communication technology (ICT) terminals, internet of things (IoT) devices, or augmented reality (AR) / virtual reality (VR) devices for communication and multi-media application.

Specifying performance requirements of digital headset/headphone interface separately for headsets and terminals enable users to freely choose their favourite type of headset or headphone in the market without losing adequate user experience.

This Recommendation is applicable to digital audio output/input interfaces that wish to support wired or wireless headsets.

This Recommendation is not applicable for terminals designed solely for analogue headset/headphone usage.
