URbeats耳机 urbeats headphones

我在加拿大买了一个urbeats的耳机，但在国行iPhone6上用不了（声音可以播放，但线控无法使用），同学中有日本购买的iPhone 6s，线控则可以正常使用。我的版本是ios9，同学的版本是ios10。大家有遇到过这样的情况吗？谢谢大家！

I bought a urbeats headphone in Canada, but the Mic on headphone doesn't work on my phone (iphone 6, bought in China). However, when my Japanese friend try the headphone on her iPhone 6s (which was bought in Japan), the Mic works well. The operating system of my phone is IOS 9.3.4, for my friend is IOS 10.1 or higher. Has anyone met this things before? Thanks!
