I currently own Panasonic HTF600's with Beyerdynamic valor pads and I feel it's time for an upgrade. I currently have them plugged into a Mbox 2 music interface and I don't think they are bad for the price but I get an annoying rattle buzzing sound with certain sounds especially bass. When I'm not using headphones I use my Mackie MR5 reference studio speakers.
That being said I'm looking for a new pair with a $250 budget, this can also include buying a headphone amp such as the fiio or whatever is recommended.
I mainly use my headphones for listening to music, games, and use them for recording music. I mainly listen to Electronic, Indie, Ambient, and some Rap and Rock here and there Examples: (Tycho, M83, Amtrac, Little Dragon, Daft Punk, Cut Copy, Washed Out, Toro Y Moi). I do find bass important but I also don't want it to be overkill. Another important thing is comfort, I'm also willing to rip off my valor pads if needed.
I've been doing some reading on the Beyerdynamic DT770 and 880, what do you guys recommend?
