I've always loved high quality audio, so I'm seeking to buy a good pair of closed over ear headphones. Right now, I'm rocking some $15 in-ears, which are good, but I'm looking to step up.
I've done research on all four of these headphones. I started with the ATH-50s and was encouraged by all of the positive reviews. But there were several complaints regarding proper balance in regards to mid-level frequencies. Links and suggestions directed me to Ultrasone HFI 780, which are my primary point of interest right now. But I have also heard many good things about the others referenced in the title.
One of my concerns is that I'm not seeking to use an amplifier at the moment. I just want to be able to have a good pair of standalone headphones. Although, I will be happy to hear any suggestions with amplifiers.
I have also looked at Beyerdynamic DT-770 Pros. However, the lower impedance models (32 ohms) are considerably more expensive. The 80 and 250 ohm models are less expensive, but I was concerned on being forced to use an amp to at least achieve a reasonable quality. So if any suggestions can be made, or if any explanations are offered, they may become a consideration as well.
I have a very broad musical palate.
Several genres and artists just to help gauge suggestions:
Metal - Metallica, Iron Maiden
Electronic - such as house and dubstep
Jazz - John Pizzarelli, or Big Band
Indie - Elliott Smith, The Antlers
