Starting this new thread because this subject/question keeps arising about
these two top headphones.
Are the MDR-Z1000 and MDR-7520 identical other than the color, supplied cable, and support offered by Sony?
("Support offered by Sony" = since the 7520's are part of Sony's "Professional Division",
Sony offers immediate telephone support and faster repair turnaround if there's an issue with them).
Both headphones are described by Sony as "Studio Monitors"
The 7520's marketing efforts are geared towards the professional market,
while the Z1000's are focused on the home audiophile market.
In the USA, both were announced and released at the same time.
Both are available in the USA and Europe, but evidently only the 7520'a
of the two are available in the UK.
The MDR Z1000 headphones are made in Thailand, where Sony has been making their headphones
for years. The stock cable, however, is made in China. And, while I've not yet seen manufacturing information
on the 7520's, I would have to assume it's the same once again.
The technical data i.e. specifications provided by Sony for the two headphones are identical.
