Negative Positive
Title: Not what it used to be
Review: I bought my first pair of 7509HD in 2002 (made in China) and have been happy with them ever since. But the pair I recently bought in 2012 (made in Thailand) sounds totally different - exaggerated bass and low mids - the usual stuff you find in most headphones nowadays. Looks like Sony decided to make them more mainstream and totally killed the product in my opinion. So don't expect old crisp reference sound from them - it's gone.
Is the review positive or negative?
