@Jyri I am having issues with the cable after using the headphones for a short period. the sound keeps cutting out. i believe it's the cable going into the Mic is not connected right.
sirkuttinSorry i´ve missed this message. Are you living in USA? Strange if the cable stops working properly after a short period but we can arrange new cable. In case it wasn't the cable you can return the cable and we´ll swap the pair. Can you send us a contact form or call our customer service? They will issue a RMA number and get the process forward. https://www.optomausa.com/us/tech-support/contact-us-americas.aspx
Sorry for the inconvenience and trouble.
JyriHi Jyri, i have tested the headphones with another mmcx cable and this cable does work fine. It's odd because if i lightly tug on the cable right where the cables go into the mic piece it works. if i move around it cuts out. filling this out now.
