Nope, the DT 1770/1990 or Amiron Home treble doesn’t bother me. It’s a treble texture and treble fidelity thing for me, I can handle somewhat bright treble. The T1.2 just had too much, if it was a few dB less I probably wouldn’t have an issue with the T1. The best treble on a Beyer I heard has to be the DT 48/480 but those are the definition of acquired tastes and love or hate. It’s softer than the DT 1990s but the Amiron actually has just as much if not more treble(more extended treble for sure, the DT 1990 rolls off a bit quicker in the upper treble), the DT 1990s have more upper mids and have a drier texture to their sound. The Amiron may still have too much treble for you, so they are definitely something you have to listen to. When it comes to not having a lot of treble, the DT 150 is probably the darkest Beyer I’ve heard.
