Sony MDR-7520 - Page 12

post #166 of 1668

Okay, so I received the Shure 840 pads today and installed them on the 7520. Installation was a breeze, they're slightly larger than the 7520 pads in almost every way.

 

In terms of sound signature I'm not noticing any immediate differences, although I think it filters the highs every so slightly because the fabric that covers the drivers is slightly thicker.

 

Comfortwise my initial impression is that it's very comfortable. The 7520 pads are about 15mm deep, whereas the 840 pads are a bit over 20mm deep. Which leaves a bit more breathing room for your ears.

 

Will report back after some more testing though.

 

Edit: here are some pics.

7520 with Alpha Pads...

that would be epic! LOL (not sure about sound though... but I just want to put ALpha Pads on every headphone for some reason... :p)

I don't think he likes headphones with a strong bass period. I remember him saying in another thread that if he hears the bass of a headphone right away its a red flag. (something like that). 

 

A lot of people with those similar tastes find most bass strong headphones with muddy(or another bad adjective) bass because it distracts them from the rest of the frequency range

+1

I want to do that too.

 

Are you going to get these gelocks and compare them to the mt220 before I do? are the mt220 pads changeable like the 7520? I already have the yammies coming and need a little more funds for the mdr.

 

IMO the sony's don't look that great but they look like they have a very sturdy construction. They also look like their dollar but like a serious headphone.

It would interesting to know what amp/dac you used when hearing the 7520 as muddy.

 

I am typically using my 7520 on three different amps:

 

1. Internal laptop soundcard

2. Benchmark DAC1

3. TC electronic BMC-2

 

1 is muddy as hell, flat, lifeless and veiled.

2 and 3 are amazing in every aspect. Not muddy.

Not planning on getting the Sonys yet unless I unload some of my stuff first! ;)

So you'll definitely do this first! ;)

So here my updated impressions of the Shure pads vs. the Stock pads:

 

The most obvious difference I hear is that the Shure muffles the sound a bit, compared to the stock pads. This is because they use some sort of thin foam to cover the driver, instead of fabric or mesh. This does mean that if feels more comfortable on the ear compared to the stock pad. The way I tested this though is that I put the stock pad on my left ear and the Shure pad on my right ear and I could hear an obvious imbalance in the volume level (left being slightly louder, i.e. less filtered than the Shure pads).

 

Now on some closer listening, the highs seem to sound less natural and a bit more metallic. As if it's being diffused. To give you a better idea of what I mean, I was listening to the song 'What Do You Want From Me' by Pink Floyd (which I think is a well mastered recording and has a nice soundstage) and there is an almost constant hi-hat playing throughout the song. This hi-hat sounds nice and crisp and has a fairly short decay when I listen to it with the stock pads. But with the Shure pads it sounded slightly more diffuse, somehow metallic with slightly longer decay. It's almost like part of the sound wave is reflected off the foam driver cover back into the driver (but I'm merely speculating on this part), or bounces around for a few microseconds before it reaches your ear, since the drivers are angled. But whatever is actually happening, I don't like what it does to the sound. Highs don't sound as natural (well, at least hi-hats don't).

 

As for the bass, it's hard to tell. I think it's getting slightly more boomy, but I'm not completely sure. Kind of like the boominess of the cotton mod, which is very subtle, but there. But this too I need to give a closer listen.

 

Also the sound stage seems to get a bit wider with these Shure pads, but it also does something to the sound I can't quite put my finger on. Not sure if it's an improvement or a decrease in SQ, but will give it some more listening, probably tomorrow.

 

I might also consider removing the foam driver cover from the Shure pads and replace it with very thin fabric from an old hiking t-shirt I have. All I need is a scissor, thread and needle for that (which I all have :)) Will see about that after some further testing.

 

I'm also starting wonder now how the Shure 940 pads will sound (which are made of fabric, instead of the pleather on the 840 pads) with the 7520. Perhaps another thing that needs to be investigated :) Heck, maybe even the new Shure 1540 pads will fit this 7520 :P

I did?

 

I believe I said something to the effect that I found a slight muddiness in the bottom in comparison to the Focal.

yes, thats how I understood it both steaks are very tender and tasty yet there are slight differences when comparing.
(sorry vegans) :-)

I have the Shure 940 which has smaller opening for the driver as I can tell from the pictures between the 840 and the 940 pads. No idea how that would affect the sound. Maybe the SRH240 pads being the cheapest maybe a option?

If you replace the Z1000 for a pad of MDR-ZX700
I think to be a sound from the Z1000. Although price is 9,000 yen or less, it was fun in the left and right.

At least based on google pictures they seem to have puffier pads, could be wrong

 

Z1000 vs ZX700

Are the Z1000 cables available for purchase anywhere?

Some question

Maybe, but so far I haven't been able to found any place that sells MX700 replacement pads. They do look slightly puffier, but sometimes pictures can also be deceiving.

So another update, on second thought I don't think that treble effect is as bad as I initially described it. There is still a difference, but it's a bit more subtle than I initially thought I heard. (or my ears are just getting used to it).

 

I do think these pads are quite a bit more comfortable than the stock pads. Will continue listening with them.

Interesting, does that mean that it's not very suitable for use in unamped portable setup.

Have ordered mine a couple of days ago, btw, will compare to Mad Dog 3.2 and MDR-1R.
