I'm looking for over-ear headphones that would be best for mainly movies and hip-hop/rap music. Now i have akg k66 that i bought like 10 years ago, they sound OK to me, though they lack bass impact in movies and they don't create that surround sound, maybe I'm expecting too much from Dolby headphone technology that came with my Asus Xonar DG? So far i came up with these:
1. Sennheiser HD 555
2. Sony MDR-ZX 700
3. KOSS prodj 100
Would i feel any difference or would it be smart to buy something more expensive?
With the Xonar DG, you want to be careful with using headphone designed for the "portable" market.
Headphone designed for the portable market usually have a low impedance (resistance, measured in Ohms), low impedance headphones do not mesh well with sound cards and a motherboard's built in audio.
With the Xonar DG, try to get a headphone with at least a 50-Ohm or higher rating.
The ZX700 are 24-Ohm and the Pro DJ 100 are 38-Ohm.
Check out the Technical Pro HPT990 (60-Ohm), DigBuy sells then on eBay for $69.99
