I was expecting from amazing reviews on the Internet that the 7509HD would blow me away compared to my existing 'phones. They didn't. They are certainly excellent headphones, but compared to the 7506s, the sound is a little hollow and distant, especially in the midrange. It's hard to describe, but when I'm listening to the 7506 all frequencies of the audio spectrum appear to be coming from the same source. On the 7509HDs, however, the mid-to-upper midrange appears to be coming from a little farther away than the highs and lows, giving a little bit of an empty sound.
It's fairly clear that the 7509HDs have a flatter frequency response than the 7506 (which tend to exaggerate the upper mids and bass a hair), but I find that overall my 7506 have a more pleasing sound, at least to my ears.
As of right now the sound of my 7509HDs is a hair brighter than my 7506s as well, but I'm going to assume that is because the 7509HDs are still brand-new, whereas my pair of 7506s are well past the break-in period. And even though they are brighter, the sound isn't harsh.
I also prefer the 7506s in terms of comfort. In addition to the 7506 earcups fitting around my ears more snugly than the 7509HDs, the 7509HDs are a little loose on my head (even though it's admittedly a little large) where the 7506 are not. And the 7509HDs weigh more, so they are more likely to move around. The build quality on the 7506 actually seems a little better, too, with a little less plastic.
Ultimately the MDR-7509HDs are a great set of headphones and I will definitely be keeping mine, but if someone is debating between the MDR-7506 and MDR-7509HDs I would have to vote in favor of the 7506, and not just because of price. The 7506s are just that good, and the fact that you can get two pair for the price of the 7509HD doesn't hurt.
But first, the good: I owned the previous (non-HD) version for nearly two decades before I had to replace them (last month), so rest assured the build quality is exemplary. The sound is very balanced, the bass is quite distinct and punchy, the highs (reverb tails particularly) smooth and clear. The mids are unobtrusive, and feel just right where they are (not hyped). The fit is very comfortable, the headband is reasonably padded and flexible, without a hint of looseness.
The bad: nothing that you wouldn't expect from a closed design. You get good isolation but a hint of boxiness perhaps (in fairness, one adjusts to it very quickly, say, after playing half a dozen of your favorite reference CDs, and then you forget about it).
The ugly: not ideal for outdoor work in tropical climates (the ear pads will feel very sweaty quickly).
Summary: you can buy better headphones (Sony's own 7520s, for instance, or typically, the HD650s), but you'd have to spend twice as much for less than a (ballpark) 30% improvement in quality. Ideally, you'd want the 7509s and the HD650s if you do a lot of late night home recording or mixing, but if your budget's tight, you can't go wrong with those (and they're great with iPods too).
Audio Performance was noticeably better compared to my old headphones, but not $300 worth of improvement.
Other reviews of this product rated them quite well. If I had a do over, I would pass on these for the price.
I still use my monitors, though, because these headphones can get kinda heavy to wear for long sessions at a time. They are pretty comfortable, just heavy. Also, inherent with most headphones, ear fatigue can sneak up on you pretty fast. Keep your levels low.
Overall, one of my best purchases. Get these.
about 1/3 the price of my old ones. If they are not the same quality, I cannot detect it. I work on old stereo components, and
don't always want to hook up speakers. These do the job, and sound great just for easy listening. They are not quite as comfortable as the old ones, but are not uncomfortable.
