It's funny what we regard as a 'low' price.such a low price.
I'm guessing you might listen at higher level than most - but I would have thought it would be too loud before noticeable distortion.Over a week listening and there is one flaw with the DT990s. Tickets popped up for a Killing Joke tour, so I now have one and that prompted some Killing Joke listening. The DT990s don't do a wall of sound noisy punk rock. There is a sound that is like crackling cellophane, as if something is distorting in the treble. If I really listen for it, I can just hear it with the AKG K271s, but I had not noticed it before. The AKGs are far better when I want some punk rock.
The DT990s are very unforgiving of noisy, busy music, as they reveal more of the treble than any other headphone I have owned. I suspect the Hifiman HE6 I had a loan of a few years ago are the most detailed and revealing of all the headphones I have listened to, but there were no distortion sounding issues, even with the noisy stuff.
Headphones are every bit as subjective as speakers, where no pair does everything right.My AKG K271s still rule the roost.
No stray hairs!Headphones are every bit as subjective as speakers, where no pair does everything right.
Bit of a long shot, but I wonder if your Beyers have the hair issue. Owners of one Beyer model (can't recall which) reported frequency-dependent distortion caused by a single trapped hair touching the driver (I know it sounds like some April Fool joke).
