I've had the pleasure of enjoying the mmcx upgrade and Empathy CL re-cabling of my SENNHEISER IE800 IEMs over the last few days - Superb build and audio quality from true specialists in this field - The OEM kevlar cable had given up the connection to the drivers early this year (an all too common fault on this range) and side by side it looks like a strand of cotton in comparison to the 2mm twin core helical Empathy replacement - So if you're on the fence on whether to commit to an upgrade, you can do so with ultimate confidence (the only pain is the lengthy wait whilst in transit and the limited payment methods due to VA residing in Belarus and within the current conflict zone with the consequential restrictions)
