Got my T1-E a few days ago. Not good so far unfortunately... Looks like mine have pretty much zero bass. Details are OK but honestly not even as good as the pistons.
Tested out of the box and currently at about 30 hours without any significant change in bass. Details have improved sightly and treble seems a bit smoother.
Also note mine came from penon, box says T1 Enhanced on the back side.
Maybe they'll suddenly have bass after more burn in, but it's starting to look like there may be some issues with these things
Good news everyone!
After about 100 hours of burn in, my T1-E have bass now! I may buy another pair from another source for comparison purposes but frankly the change is pretty unbelievable. At 0, 30, and 50 hours they had absolutely nothing in terms of bass. But somewhere between 50 and 100 that all changed. Will have to see if it improves even further with more time, but at this point it's got waaaay more bass than tenore but similar levels of enjoyment.
