I have a pair of dt770s and a set of speakers (I forget the brand / model) and there’s a huge difference between audio quality.
Obviously headphones aren’t going to have the same feel as speakers, but is there some kind of piece of hardware or something I can use to get better sound out of them? I currently have my headphones plugged directly into my motherboard.
You could get a DAC with built in headphone amplifier. You normally connect it to the computer thru USB and this will give you improved sound quality.
