TonsharadeonI suggest the Beyerdynamic DT880 Pro 250 Ohm semi-open headphones. On Amazon, you can buy the Beyer DT880 Pro for ~$230 new currently. These headphones are designed for tracking, and mixing; the frequency response is flat, with a crisp, fantastic bass response. The soundstage is excellent.Nothing can beat beyer in comfort, but i feel like the bass is just not as punchy as id like in those
I currently use the Beyer DT880 Pro 250 Ohm w/ a Schiit Audio Modi 2 DAC, and Magni 2 Amp as a stack. I have no complaints about the sound quality of these headphones what-so-ever.
DT770 has loads of bass (closed though). DT990 comes pretty close in amount of bass, is fully open and fits your budget.
