They're accurate. The good the bad and the ugly all gets pumped into your ear holes mercilessly. It's a good idea to listen to a lot of recordings that you aren't familiar with to get your bearings. Mastering jobs that are loud are grating are completely offensive to the ears and will cause fatigue quickly almost instantly for me. For example I picked up a ticket for the upcoming Chelsea Wolfe show because it's going to be a total goth girl convention and I am into that. I checked out her new album with the LCD-X and it hurts to listen to because it's a hot master with chopped off dynamics. That's just one example. In contrast to that I checked out the new Brittany Howard album and its smooth and flowing and dynamic. I can listen to great recordings all day, but can't listen to metal at all because of the mastering jobs done in that genre are attrocious. All of the distortion in the mastering stage and the smashed dynamics get told as it is. They are audio engineering headphones. Accurate more than euphonic.
I am not an expert and someone can correct me if I am wrong, but I think that the fixtures that those measurements are made with are not accurate over a certain frequency and that data is junk data. The LCD-X is darkish neutral at the very top.
Another thing to note is that even though they're efficient, they have a minimum requirement listed on the Audeze website that I absolutely agree with based on experience. When underpowered the dynamics fall flat and the underpowered amp distorts the bass and that will cause fatigue. Any amp is fine, just no phones, dongles or audio interface outputs unless its one with an especially juicy amp built in.
A day later now I think I agree with this.
They mercilessly shove everything to you. For a while I thought headphones could not be "complete" but these feel like they really do give you EVERYTHING, including the ugly.
Sometimes I notice this though: guitars can sound plasticky/unnatural as if the timbre is off, and the vocals can sometimes sound like they're not vocals - like they're synths who can sing or something. Is it because of the high mid/lower treble recess people mention?
I don't know what flat is or if it exists, but LCD-X do not sound as what I think should be flat. I think most audio has way too much treble and what comes out of the headphones/speakers does not sound like it does in the real world. I'd say the real world is flat (real), and to me the HD600 sound most like the real world, yet people call them veiled. But I guess I'm leaving the part out where almost nothing sounds harsh on HD600, but it probably should if the track IS harsh?
I also agree that some tracks sound like literal miracles and most metal was not listenable, unless when oratory1990 EQ was used. That made me sad, but I can enjoy my D7200s for metal. Some albums sounded like literal mush without exaggaration. Vocals unclear, bass all over the place, cymbals splashing over everything, guitars mushy.
Some were great, like Nightwish. Nightwish rocked, man. Everything had its place. And Evanescence.
To me they sounded best with high-end pop music (Selena, Loreen, Mariah Carey, Taylor Swift, etc...) and experimental electronica with a lot of pauses (Kalya Scintilla, Infected Mushroom). Trance had great tracks and bad tracks.
I tried Devin Townsend - Ki and Ghost. These ambiental albums sounded like literal heaven. It was as if I was surrounded by TONS of pure, untainted, full, 3D spacious huge sound. I didn't know a headphone could produce so much different stuff at the same time, but not talking individual elements and "oh I heard a thing I didn't hear before" but like but the decays, the ambience, everything just blended and sounded utterly huge and vibrant, something I never heard before. I heard every minor volume change of every element, every minor EQ change between vocal parts which used to sound the same on other headphones.
The mixer headphone outs are extremely powerful, they blast my HD600 at 30% volume. I again say I've yet to heard something better than that setup, but I never tried any amp above 700€ so... And the audio interface main outs are extremely clean (it's basically a DAC out, doesn't have to have much power). So power and quality of the signal are not an issue here. Finesse maybe... But I never liked any amp signature except Fiio E12 which I regret selling.
Are Crinacle measurements bad?
