From the looks it doesn't look long enough. For custom SR1 cables one cable guy I contacted mentioned it would need to be "mmcx long tube for recessed socket". But hard to tell from Meze pics. It doesn't look long enough and/or it is too wide.
Anyone using this cable? The MMCX termination on it doesn't look compatible, but I may be wrong:
