I am a new poster as of today! I signed up specifically to thank MLE and the rest of you guys for this wonderful in-depth discussion. I WAS going to get the PC 360s. I had them ordered and cancelled it...TWICE, as I am wracked with indecision as to what I want to use for my gaming/music headphones. I have a Wii/360/PS3/PC and game actively across all of them. I also enjoy listening to music, and can see myself making an extremely large upgrade in audio-quality from my current headphones (Motorola Blue-tooth which are pretty awesome, honestly). So, I am looking for a set of headphones that sound phenomenal for single-player gaming, yet still give good positioning, as that IS important in single-player games as well. I *DO* see myself using a chat feature sometimes in the future (Hello Mass Effect 3 Multi-player), but I place FAR more of an emphasis on sound quality, and would highly value the ability for these headphones to transfer over well to music listening. I'm willing to do a secondary mic setup if the sound quality on the higher-end pieces crushes that of the PC 360.
I am currently considering the PC 360, HD650 or HD598's (Depending on which you guys think would sound better for single-player gaming), and the DT990 (or 880..whichever has best overall sound quality). I am of course open to other options as well.
I've already purchased the Astro 5.8, that is on the way. I just need to know whether to settle for the PC 360 if they are truly superior for gaming music/FX, or to bite the bullet and purchase an AMP and step up to the HDs or AT brand.
Finally, as for price, I cannot go higher than 400 dollars. I would rather spend 200-250, but I understand that may not be the best option if I need to purchase an amp.
Any guidance you can give would be great. Just keep in mind that my primary focus is on top-quality single-player sound quality. I want Skyrim's music to sound flawless as I realize that giant is sneaking up behind me!
