I have had these for about a month, and while I have never tried the Elite 65T, I sweat profusely while exercising, and after about two miles they start to work free in my ears, to the point the left has fallen out. I’ve tried all the different tips, including foam tips and they still start to slip after about 30 to 45 minutes of exercise. Kind of disappointed, in that the more I sweat the more the left earbud starts to pop and crack. Not sure why, I contacted Jabra and they told me to turn off Auto-pause, but that didn’t resolve the issues.
Hope this helps
