Questions about Sennheiser CX 300S

The microphone on the A7 2018 phone does not work. The media output works fine. Both work wonderfully on the laptop. Does anyone have a tip or the same situation?

Are there replacement ear attachments for these headphones?

Can you hear it when you rub the cable somewhere?

In which country was the product manufactured? I can't find the information either at Digitec or at the manufacturer.

I'm looking for a pair of headphones with the cable running down the back of the neck, so one is longer than the other... is that still the case with this one? unfortunately you can't see it in any of the pictures. Thanks

Information incorrect: Integrated microphone and integrated remote control for call and music control. https://de-ch.sennheiser.com/ohrhoerer-in-ear-kopfhoerer-cx-300-s
