Sony MDR-V6 vs. MDR-7506. There is a difference in sound. *** Pictures too ***

post #1 of 75
Thread Starter 
Check out my unboxing video of the MDR-7506. These are real.

After reading many threads saying the V6 being the same as the 7506, I thought I do a comparison myself. I ran both headphones through my Lehmann Black Cube Linear.  I chose this amp because it is very neutral with plenty of power to drive both headphones simultaneously.  




There overall sound signature is the same.  The MDR-7506 sounded a bit bloated in the bass department. The MDR-V6 is a bit cleaner with less midrange bump than the 7506.  I like the V6 more.  Other than those two things, they are the same in every way.  I suggest everyone to buy the V6 because they're GREAT for the money.

Thanks for the information. How did you make sure that the volumes were equalized? Lovely photos.

question.

 

are those two bought almost at the same time? one might be new and not yet properly broken in and the other might be burned out.

 

ive been eyeing the 7506 as a go-to headphone. i live somewhere southeast asia and theres nowhere i can buy sonys[ies].

 

would you recommend me a good [cheap but secure] online store that does international shipping?

The made in china(newer) or japan(older) model?

The difference could also be accounted for by differences in the manufacturing run. There's only so far QC can go, and even with tight tolerances it's not unreasonable to suppose that there might be a difference between two different production batches.

The Lehmann BCL has two headphones out providing both with enough power to drive two HD-800.

The V6 was Made in Thailand and the MDR-7506 in Japan. The MDR-7506 is older, but I ran both in for three days straight prior to the test.

Wanted to ask the same thing.

 

They are the same headphones. The only difference who they're marketed toward, the price, and the plating on the jack. 

 

If they are in fact both brand new, I'd say that the difference comes from QC issues at the factory.

Aw the made in thailand production that was before the made in china production, but after the japanese production run.

I've played with v6 alot the balance mod for the m50 works well in adjusting/tuning the bass.

 

If you have read the older v6 vs 7506 thread we know that the driver are the same sony part # and that the fact that there was one v6 with a 7506 cup and v6 cup means that they are made in the same factory(at least for that production run)

^ is there a sony rep that says so? are the drivers/chambers really the same?

 

Theres this issue about Shure mics, the SM58 vocal and SM57 instrument. Both have the same cartridge but the construct of the mouthpiece/opening is different which actually alters the frequency response of each.

 

This may be a similar case.

 

and these two cans, one is labeled "for professional" and the other's "for digital"

 

 

from my experience the 7506 is highly recommended for record mixing since it shows a lot about the record, flaws etc.

so theyre basically not audiophile cans.

Neither was the V6, IIRC. Somebody correct me if I'm totally wrong, but they way I understand the story the V6 came first, then Sony decided to more distinctly differentiate its consumer and pro markets so they split the line into the 7506 and the (different and generally considered inferior) V600. Due to popular demand they then reintroduced the V6. So given the above, the V6 used to be the mastering headphone before the so-called Pro division, which has all the 750x models.

 

However it went, I know that the V6 was very well known in studios and radio stations, and its users often sing its praise as the V6, not the 7506.

No, they are not the same.  Too bad Head Fi doesn't have stickies, but I'll post links tomorrow.

 

The 7506 and V6 are comprised of exactly the same parts, yes.

 

But they are not wired the same.  The V6 has a common ground, the 7506 has individual grounds.

 

A few months ago I bought both brand new, because I was curious.  smile_phones.gif

 

I burned them in the same.

 

I also preferred the V6's.  Softer/warmer treble, and more bass.

 

They do sound different, and whoever says that they don't probably never listened to pairs of the same age and burn in.

I think this is one of the oldest debates on Head-Fi.  I'm amazed it's still going.

The driver units on the original 7506/V6 models were the same (maybe still are) BUT there is a production difference.  The 7506 is wired with seperate ground screen for each channel for true channel isolation - that is why they are labelled as "professional".
The V6 is wired with a common ground screen (commecial) that introduces slight cross talk (30dB down) through the return channel ground, creating an image signal in the opposite ear. That ironically may lead to a marginally less focused. warmer sound that may make this model represent the mix better in terms of the acoustic interaction of the stereo signal in the air emanting from a pair of near field monitors. In other words the non pro wiring in the V6 may just make them closer to a pair of near fields in the air.

 

I bought a 7506 and a V6 brand new each from authorized dealers, and I confirmed them to be legit based on all the info detailing differences between the fakes out there are real ones.  This is my listening comparison:

They are wired differently, and they do not sound the same because of that.

I suggest everyone to buy a V6 because it is a GREAT all arounder headphones on the budget side.
post #15 of 75

MDR V6 are horrible headphones with a nasty 2k spike that ruins them.

You can do much better at the same price point.

 

MDRv6 is something people got suckered into buying years ago.

These days there is no reason for someone to get conned into buying them.

I recommend everyone stay away from them
