I'm not sure if you are telling your problem to Audeze correctly, this is definitely a issue on their end and you should have received an RMA label from them.
-Also note: This could be more than just a cable issue. They have told me that my order could have been a bad batch during the first-production run. I recommend you send in your headphone so you do not have to run into any potential problems in the future.
I have mentioned on this thread previously 2 weeks ago that my open-EL8 were having issues with sound on the right side, and it could have been a cable issue or the right driver itself. Not to rain on your parade or anything but Audeze has since responded to me personally through Head-Fi on a private message and on this forum specifically stating that anyone with the issue should speak to their support and they will take care of issues in regards to the EL-8 in their end because the headphones are very new.
Anyways, I just received my replacement headphone yesterday from them and to give everyone that is worried about their overall customer experience for headphone issues, it is definitely excellent. They responded to me through HeadFi, email, and answered my telephone calls whenever I called in (during hours of operations for support). They created an RMA label for me to send in my headphones to check on the issue, and my only complaint was that it took 2 weeks in order to get a replacement.
You should talk to Jerid by phone through Audeze's support phone number. He is the one always answering the calls on their end and has been wonderful in assisting me with the issue.
