Well, my B&W P7's are dying...the right ear has developed a crackling like a bad driver. I emailed B&W support, and they told me they only replace headphones under warranty, they don't repair any headphones. So, that's annoying to have to trash a $400 pair of headphones.
That being said, I'm looking for a new pair now for gaming. I used the P7's with a modmic and thats been working well. For my source I use a Burson Conductor 3R with DTS:X vss plugin. I need them to be closed back unfortunately, so open back options are out.
I've been looking at the Beyer DT770 or DT1770's as options, another set of P7 off of ebay or something but am open to other good options that have a decent soundstage and great imaging as I play 95% FPS. I will occasionally use them for music also, but I have a set of Focal Elegia's that I use for music so music isn't a high priority for these.
I'd say my budget tops out around $500-$600ish, slightly more maybe if it was a great deal on some higher end cans.
Let's hear some ideas!
