Headphoneus Supremus
Awww come on my friend. That sounds like more of a praise than let down. I already know you don't like the th600, it is not my favorite either, but with all due respect the th600 is worth its current price for the simple fact that a lot of the current headphones in its price range can't beat it in technicalities and sound quality. There are the more likable ones but that is only according to personal preference.
If the z7 beats the th600 technically then at 500 I better jump on it as soon as I can.
The TH600 has much more treble and most people will probably prefer it. I find the TH600's treble disgusting and would rather have none (or close to none) than what it offers. The MDR-Z7 has a better presentation and is more comfortable. It's also built better. Otherwise, the TH600 is superior "technically".
Both are slaughtered by a 32 year old supra aural in every imaginable aspect except comfort. This is my problem with them; form is given priority and function takes the back seat. Given the choice between 3 hours of enjoyment before having to take them off, and mediocrity all day, I'd pick the former, and I don't understand why anyone would think otherwise.
But again, that's just my opinion. I'm generally a weird person, so YMMV.
