Technical requirements and test methods for analogue wired headsets or headphones and corresponding universal interface of terminals

active, Most Current
Organization: ITU-T

Status: active

scope:

This Recommendation1 specifies electrical requirements and test methods for the universal analogue headset or headphone (HP) interface used in digital mobile terminals. It is also applicable to terminals with a digital headset interface combined with an external adapter for an analogue (universal) headset interface. The combination is measured as one device.

The principle of this Recommendation is to ensure adequate compatibility between the digital mobile terminal and the wired analogue headset or HP, and to provide better user experience. The universal headset or HP interface enables the separation of sales between digital mobile terminals and headsets or HPs. One of the benefits is that the user can be free to choose his or her favourite type of headset or HP that is available on the market. In the long run, it will reduce e-waste. Furthermore, the universal interface can be used as the electric coupling design in hands-free systems and hearing aids for wider harmonization.

In order to provide instructions to manufacturers and encourage them to adopt the universal headset interface, the mechanical dimensions are shown in Appendices I to III.

This Recommendation is applicable to digital mobile terminals with a physical analogue audio output/input interface. Other similar information and communication technology (ICT) equipment may also refer to this Recommendation.

This Recommendation is not applicable to terminals designed solely for digital headset or HP usage.

1 This Recommendation includes an electronic attachment.
