Submitted a warranty replacement request for my extremely troublesome T5s on October 23rd. Got the canned "will respond as soon as we can" response from Klipsch on November 3rd. Been asking for an update every few weeks, but have received no response from Klipsch support as of December 30th. Sad.
UPDATE 2/3/2021: I finally got a response from a real person on January 4th, with the typical "did you reset them" and is the "firmware up to date" response. Just to be safe, I did reset them yet again (been doing that for over a year), and again checked the firmware (it was the latest version). Connecting to my iPhone seemed a little better, but couldn't really test them under my usual conditions (working outdoors with lots of movement). Connecting to a PC I still had significant dropouts while only a few feet away from the PC. Turning my head one inch to one side (yes, one inch!) and the buds would drop connection. Turning back one inch, and they would reconnect. Today I finally received a return authorization for my warranty replacement. It took 3.5 months, but as everyone else said, keep bugging support and you'll eventually get the authorization. Hopefully the replacements will work as expected.
