Since the release of this standard, more and more manufacturers have adopted the concentric connector, which gives more choices to consumers and also has benefits on the environmental protection and the healthy development of the mobile terminal industry. Now, the universal headset interface has been included in the draft ITU-T recommendation P.381. lts internationalization will further enhance the universality of the mobile phone headset interlace. It is China＇s another great contribution to the international standardization following the standard of universal power adapter for mobile phones.展开更多
