Thanks Israel. They are becoming very scarce in the UK.

Yes, I had both as well. I find the V6 useful and some recordings are great on them. However, that top shriek can be a bit ott for some recordings.
Funnily enough, I've kind of adjusted to them and they are actually very revealing. Tonally, they seem really good with orchestral stuff as well. There is a treble peak that would help to tame it if it could be sawn off!!
They're pretty good for the cost I guess.

The difference between the MDR-7506 and V6 is small or negligable. They are terrific for discovering faults in a recording (distorsion, extraneous noises etc) because they have a high frequncy resonance that exaggerate transients (much like the old Decca London cartridge). Check the tom-tom preamp overload of San Juan Sunset from Lee Ritenour's wonderful album Rio. That engineer should have used the 7506! They have limited dynamics and the typical 1990s Sony response: exaggerated low bass, too low upper bass/low midrange and that high frequency resonance that put hiss and cymbals in the spotlight. It's always baffled me that some people call this response "accurate", "neutral" or "cold"! All my own impressions of course, but valid ones that I'd like to share. Before I had the Pioneer Monitor 10 and K240DF I used think the V6 was somehow neutral in its sonic presentation. After that I started to detest the V6. For what it can do the V6 is great. For listening to music I think of the V6 as a headache device if you get the volume settings wrong. Yuk... P.S. Loudness infected albums are tricky with this headphone.

I connected the V6 to my Roland active speakers which have a headphone socket last night.
I use the Rolands for TV and that sibilance was demolished. In fact, they sounded bassy and explosions etc were pretty good on them.
I don't know what the output impedance of the Roland speaker is or what kind of signal it puts out, but it helps the V6 quite dramatically.
So perhaps we need to look more closely at the amps that we're using with headphones?

got a pair of mdr 7506. initial impression when playing through the 3GS iPhone was. yeah these are ok. Im only used to grado's. But then after about 10mins and some other music. ouch! they go high, and people talk about grados being high. The sound was such that it gave me a headache.
so i put them on the side for a few days and had a think. I thought about the various mods i had played about with with the grado and so opened the sonys up to see what makes them tick.
The back of the chamber is hard. There is little airflow to the back, only one hole. The cables are thinner than my hair. Also dont like the even thinner cable that goes over the head to make up the connection from the other cup. This is not too balanced??
So first i changed cable, had a grado single strand kicking about. drilled a hole in the botton of the cup to accept this cable. Now both sides have a cable coming out, bit like the above mod. Pesky wound one sided, head heavy on one side cable gone! although the connector was ok, screw on to make a bigger plug.........
Next I raided the flat cottonwool pile and with double sticky tape spread and placed some cotton wool to the back driver housing. This needs a bit more thought, as it might be too thick. Not experimented with it enough.
I then made 2 more holes in the backing paper to the drivers, to get a bit more air flow and lower the bass, hoping to take the edge off the highs.
Oh one last thing, i removed the sponge foam that was wedged into the center hole in the drivers, this also improves air flow and lowers the bass.
So the results so far are fairly good. no headache, after a short listen, and no screech high, just not sure on the soundstage, need to listen a bit more. The sunriseII is powering them. Will let them be for a bit till i get used to the sound and think a little more what can be done. But so far so good. A nice headphone to have when your on the bus and don't want to stick buds into your ear canals inorder to get sound isolation.
I will update my thoughts and comparisons with the grados in a few days....week....weeks.....but i will update.

I cut an extra 2 holes in each one. Airy goodness. And put a blob of dynamatt on the front metal of the driver. Hoping with this to calm any high frequency vibrations and tuning fork effects on the sound waves coming through.
Anybody else done this sort of thing with their pair?

Dynamatt on front grill kills all sparkle. Took it off and made a couple more holes to back.
It's not a grado, but its ok for what it is. It's my bus and train headphone.

Sounds like you're going to town on them. Pity you haven't taken some pics to show us what you're doing.

They are a funny headphone. I have a kind of love/hate thing with mine.
I use the V6 which has a similar sound - very slightly different FR according to Headroom.
I find them very analytical and can sound extremely natural and as you say, at other times, very screechy depending on the material.
The do have a nasty large peak in the treble area that shows on FR graphs. That's probably what we're hearing.
Good monitors though. The one thing I hate is the cable. It's too heavy and coiled for the size of the headphone. I'd prefer a straight one.
Recently, I've been going through the Sonys and notice that a lot of them have very restricted FR. ie they don't go down particularly low and also not particularly high. (Including the V6) There is a severe roll off somewhere around 12 - 15 KHz I remember seeing, so they're not particularly extended for all their harshness.
I think that the V7502 has a very narrow FR and looks like a big hump in the middle with no lows or highs!!! The Headroom graphs are really strange in this respect. The Golden Ears site gives a better look at the 7506 but not the weird ones that Headroom are showing!!

i have just stuffed some rope in the cups to give them a bit more thickness. Sound got a bit more full but most i noticed a plus in comfort. will get on with some photos.
Thanks for the info rabbit. I think my 7506 used to be yours, as i got them from Frans. And the amp.......sunrise II........yours too i think :-)

I think my 7506 used to be yours, as i got them from Frans. And the amp.......sunrise II........yours too i think :-) yes, both mine of old!! Frans updated the amp and I sent him the headphones to try since he was very curious about them. They are excellent as monitors but another headphone I really do like for home listening which is also cheap is the Sennheiser HD202. They can be bought around £30 and work extremely well for music listening. The Sonys are better as monitors imo. They show every flaw and are frequency limited as well. Some of the other Sonys are even more limited in FR so that they are good once again, as monitors rather than what I'd call a general 'music' headphone. The funny thing is how natural the 7506 sounds with orchestral music. (And my V6) I think the V6 is a tad warmer but it's a gnats knee. Very slightly different although it's the same driver - or else it's a variation in quality control.

S! F! B! W! please read post in wanted-forsale. Would appreciate help, searching for a 7506 driver to replace dog eaten one.
Headphones were really growing on me as well, was taking pics to go on here! My bus and train trip listening need to be restored :-(

Have you tried looking on eBay? Seems to be listings for 7506 spares on there but whether they are genuine or not I cannot say . Many new '7506' are also advertised there but one seller (at least) has poor feedback and one buyer states they are not original. OTOH another seller has got feedback stating they are originals, so may be worth looking carefully at feedback - current prices all less than £20. Dave.

You know, I don't find the V6 as bad as all that up top. I know there is a peak up there and it's not a particularly extended headphone, but it does seem very natural on speech (which I often listen to as well) and you kind of adjust to its timbre after a while.
I find it very analytical but it can convey music extremely well. I find that the volume is very critical with them. Too loud and it sounds edgy but if you get the presence right with them, they are a really 'crystal' listen.
For some reason, I found the V6 slightly 'warmer' than the 7506 and I have no idea why, since it is the same headphone in essence.
The only thing Layum, is your mods aren't reversible are they? So you're not able to compare an original with the modded ones. It's a difficult one because it can be very difficult to judge the 'voicing' without a reference.
ie: while you may feel that the sound improves with something you're listening to, it may in fact sound worse with something else and you may introduce colourings that you're not immediately aware of.
The reason I mention this is that I have felt for a long time that the Beyer DT770 is a fine closed headphone; until I put on a K550 and directly compared - I found the mids on the DT770 really poor by comparison but had no idea until that point. I just turned the volume up until I felt the presence was in 'focus'.
You need to be careful with mods in case you're actually making them worse. I must admit, the V6 is actually an impressive headphone for daft money since it does seem to resolve very low detail.

Nope. Not reversible, not the holes in membrane. But the others are reversible. I know what you mean about doing negative gains, but I enjoy being brave sometimes. I'm looking forward to getting the driver off full compass. So I can get using them again.
But as I'm not in the US it's hard to squeeze a simple postage quote out of them. It would be easier and a great help if someone in US ordered and forwarded it on to me. It's taken them nearing a week now from my original quote request.

Yes, with that link its certainly worth getting a new pair. Then I have some spares so can rest easy should I get the urge to change things even more. Thanks.
