Greetings, In 2016 I got myself the at the time new Beyerdynamic DT 1990 Pro, they were pretty much my first "high-end" headphones. Prior to them I had my Beyerdynamic Custom One Pro, Sennheisers (forgot which model) and the Philips SHL5800. Out of all those headphones, I felt like the Custom One Pro were by far the best. Once I have accumulated a reasonable amount of money, I decided on spending it on a new DAC+AMP and a new pair of high end headphones, so I got myself The Element from JDS Labs and the DT 1990 Pro from Beyerdynamic, the reason I got them was because I have never tried open headphones before and also because I really enjoyed the elegant and slick German design. I read and viewed pretty much all of the reviews that were available at the time and committed to the purchase. Unfortunately, still to this day, I really dislike them and feel like I have wasted a big portion of my money. Since when I got them which was back in 2016, they have been doing nothing but sitting in that professional audio box that came with them. Reason being the sibilance which is pretty much unbearable... It is hard for me to assess my personal sensitive to sibilance and treble, but certain songs made the DT 1990 physically unbearable, the amount of sibilance and hissing I would hear would be unbearable. But even tracks with moderate amounts of highs would output unpleasant amounts of sibilance and hissing to the point where I just got mad and decided to give up on them and keep on using my Custom One Pros. I felt like I wasted 600 CHF for something inferior than what I had. Obviously, things like clarity and soundstage as well as many other aspects of sound were noticeable better when compared to the Custom One Pro but I felt like the sibilance pretty much diminished all of those advantages making the headphone pretty much unusable for me. As Switzerland is not really a country full of audio hardware enthusiasts, I had trouble selling my DT1990s and still to this day they remain unsold. This whole situation left a bad taste and since then I pretty much gave up on enjoying any music on any type of stationary set-ups which would involve various high-end audio hardware. But as someone who really enjoys listening to music, here I am back again. With a bigger wallet, more experience in the audio sector and newly generated enthusiasm. Now I always looked up to the LCD line-ups and with the introduction of the new LCD2 Classic, they got me interested. Would they be something that would bring back what the DT 1990 Pro took from me? A pleasant high end audio experience?
