My old headphones don't work

[xratola]

I own a pair of sennheiser cx-275 that come with handsfree in-built and they don't work with my Lumia 930. Those headphones work with windows phone, since they used to work with my Lumia 920 before but somehow don't work with the Lumia 930.
Anything I could do?

Do other headphones work with your 930....in other words, you're sure it's not a fault in the phone?

I don't know, the headphones that came from Nokia work perfectly but my sennheiser don't.

Do your sennheiser ones still work? Did you try it on a laptop or another phone recently

They still work ok my Lumia 920 that's why I don't know what's happening bcs it should work theoretically.
