ITU-T P.383 PDF

This Recommendation specifies technical requirements and test methods for wired or wireless headsets and corresponding digital interfaces. See Figure 1.

This Recommendation aims 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 terminals, Internet of things devices and augmented reality or /virtual reality devices for communication and multi-media application.

Specifying the performance requirements of the digital interface separately for the headset or headphone on one hand and the terminal on the other enables the consumer to combine commercially available hardware of both types without losing adequate user experience.

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

This Recommendation does not apply to terminals designed solely for analogue headset or headphone usage.
