Hello.
Perhaps i am beating a dead horse here but i need an advice.
 
I currently own Panasonic HC 500 which i love for NC and sound quality.
 
Mostly i listen to dubstep and some TV/Movies.
 
No, i don't have dedicated amp, but i do have DD amp instead - sony entry level for my PC (sound via toslink) and mid-level yamaha for TV/Movies.
 
On PC i use EQ alot for various music.
 
I got my hc500 at a local store couple of years ago for $80 (what a steal!).
 
Although sound quality and NC is great (IMHO) the build quality is not:
 
- i got brocken plastic on both sides, just above the cups (fixed with electrical tape)
- one of the cup cushion has bursted and now i have to deal with foam getting out
 
I've tried hd598 but they weren't NC and they didn't worked for my PC setup (my PC is a bit noisy with all the fans), so NC is a must.
 
I've listened to QC15 - NC is awesome (better than hc500), not sure on audio quality.
Dr Dre Pro - are ok but i thought they were a bit muddy on low fq. (Not sure if those are NC though)
 
Currently i am leaning toward crossfade lp but i am not sure if they have NC anywhere close to hc500.
 
So i am looking for NC headphones that are comparable or better than HC500.
 
P.S. i have rather large ears but hd598 were a bit big.
 
P.P.S My budget is under $300.
 
Thanks alot.

So i got crossfades lp.
...... I am not happy.
Sound.
Lows are not there - i have to amp 30 HZ by at leat 8db to get something.
60 to 120HZ i have to de-amp by 8-10, otherwise sound is muddy and boomy.
Mids have to be de-amped, not by much, though.
Highes (14-18kHz) have to be de-amped by 3-4 db.
 
Noise isolation is good - i don't hear fans.
Slightly uncomfortable after 2 hours of wearing - my ear is pressing against speaker case (inside), cushions could be taller.
 
What is this burn in i hear about - how long does it typically takes to "burn in"?
 
If someone had XB700 or XB500 - how are they compared to crossfades in terms of comfort and sound quality?
