Picked up my second Timeless. Yes, I'm hardcore. Going to make one pair my "stay at home" pair and bring the other pair to work. Comparing them out of the box against my "old" pair (about 50 hours on them), the new ones are definitely brighter and shallower in soundstage. General sense of QC is that they're pretty much identical, I think the new ones just need some break-in time. I'll let them burn in for a while and then test them again back-to-back. Even with TOTL IEMs in my collection, I can't stop listening to the Timeless. They just have an addicting character to them, a perfect balance of detail and ambience, at least for the music that I listen to.
In my experience, they do not like to be overdriven. Keep the volume at a low-to-moderate level and you'll be rewarded with improved clarity, imaging, and soundstage. I probably listen a lot lower than most people, around 65-70 dB generally. But I've noticed that there's a sweet spot with the Timeless where the magic happens. I typically turn down the volume until it's "too quiet", and then creep it up slowly from there until I hit that sweet spot. Then I leave it for the rest of the entire listening session. It just works for me. Give it a try. Good luck and good listening!
