國外的聽感慢慢開始出來了，簡單節錄和翻譯一些評論：

Before knowing about the different ear-pads I felt like the DT 1990s had a
little too much low end coloration to be considered a true reference-class
headphone, this is a term I hold at a unreasonably high standard. But their
sound quality was still fantastic and detailed. Then while reading through
the manual, guys always read the manual.. seriously do it, I figured out that
I was listening for the entire first day with the ‘balanced’ ear-pads which
add a little extra to the low end. Upon learning this I switched out the
pads, again see the manual on how to install them properly, to the ‘
analytical’ version and got more of a response I was expecting from a mixing
grade headphone.
預設的Balanced耳罩對監聽級耳機* 來說，低頻染色有點太多。
換上Detailed耳罩之後，聽起來比較「監聽」
（原文是Reference-class，我解釋成監聽耳機）
While listening to them with the balanced ear-pads this sound characteristic
shifts slightly into the domain of a warmer headphone.
用Balanced耳罩聽的時候有點偏暖。
There is a slight recession in the mid range allowing more room for the low
and high end to breath and develop.
中頻有些許的凹陷（有點像990？）。

德文網站，我是用Google翻譯成英文再看

The Tesla-2.0 generation plays from their stocking and due to the
particularly thin and lightweight design attack rich sounds reflect extremely
precise.
Attack短的聲音在1990pro上非常的精準，瞬態相當好。
Compared to my DT 880 Pro I also notice that I hear end reverb individual
percussive sounds on the DT 1990 Pro much longer.
跟880Pro比起來，打擊樂的殘響在1990Pro上變的更長。

我自己是有刻意略過一些諸如「相當平衡」、「沒有的頻段突出」這類的評論啦...
鍵盤試聽的話，有點像我印象中的，還沒開聲的1770p
昨天去問了一遍，1990p似乎還沒有預定進來台灣的時間和消息
