are my new DT 770 Pro 80 ohm broken?
whenever i listen to music and turn up the volume the bass gets really distorted (example of song mumford and sons - woman). same results on both my integrated audio soundcard (some Asus Supreme Fx thingy) or my focusrite solo 3rd gen.
the onboard soundcard should power headphones up to 600 ohms and focusrite up to 200 ohms if i'm not mistaken, so what might be the cause?
do i need an amp/dac for it?
