They are NOT harsh.
Your opinion is biased by the DT880s which are bass heavy - try an equalizer if you must listen to 128 kb/s mp3s, low quality TV-rips and cam-videos.
These are $300-500 headphones, they are supposed to be detailed and revealing. That's what you pay for. If you want a muddled sound that smears over every imperfection you could have bought a pair of $50 headphones.
My entire collection is FLAC, 720p and 1080p video. That's what's needed to do these cans justice.
