Hi, I have been reading this whole thread for a long while. I would like to buy a good headphone for gaming/music mostly for fun, according to reviews and user opinions the Beyerdynamic DT-770 Pro or DT-990 Pro are good options.
I play on PC and own the Asus D2X, I don't want to spend much more than 150€/200$ (I live in Spain). I have found the DT-990 Pro, DT-770 M/PRO for almost the same price, 160€.
The problem with the DT-990 pro is that they are only sold with 250 ohm impedance, just Premium one's are 32 ohm and they are too expensive.
All of you suggest for the Beyerdynamics to be powered by an amp, but i don't understant that point, from what i've read, an external amp only gives you higher sound output, (or alters sound quality with it's own signature sound), I always play at night, when all is quiet, is it really worth it an amp in my case to power a 250 ohm headphone?
PD: I own a igrado headphone (use them while in the street) and if i connect them to my PC i only need 20% volume...
The Takstar Hi2050 are only 60-Ohm, so they should work with with your current sound card and and they sell for $65, sold on eBay and shipped from Hong Kong.
