I feel bad sound when I mowe right cup of my headphones on my ears

I have the Audeze El8 and my only issues was the cord would break after a while and I would lose my stereo left or right, I would be super gentle but the connection to the ear cups would cut out for apparently no reason, no visible damage would occur. Twisting the cord ever so slightly would bring back intermittent sound. In the end I had to send it to the company multiple times. I would have a problem diagnosing the exact location for me to fix myself, it is a flat stereo connection cord that I loved but no idea what to do……I have only owned one pair of Audeze planar magnetic and when they work its heaven……..it would be a dream to fix this issues myself.
