I'm currently rocking a pair of HD58x with the hybrid ear pads and I love it. I'm using a Tascman US-2x2HR to drive them. I'm planning on recording some vocals for commentary and the mic is picking up audio from my headset. I'm blaming my open back headset, so I'm looking for a closed back headset of similar price and quality. I'm quite picky about the build quality so please keep that in mind when recommending. Thanks in advance.
