Actually, highly sensitive, low impedance headphones like the 7520 are the hardest to drive well.
People often confuse getting a lot of volume out of an amplifier, with being easy to drive.

High impedance headphones mostly just need a lot of voltage to drive them loud, though ideally you would still be using them with a low impedance headphone output.
Low impedance headphones need a lot of current and a very low impedance amplifier - less than 1/8th the headphones themselves. And they need a very quiet source to avoid any background hiss.

As far as sealed headphones go, the MDR-7520 are my favorite by quite a bit. I think it's a shame they are so often overlooked, because they are such a good headphone.

 

Very true. I generally just use these with my Iphone but they scale really well and sound flat out amazing driven by my m903.

+1. I'm going to try this as well. What's the best way to remove these earcups?

Apple's hardware actually has relatively good headphone outputs now. I don't know about how much current they can supply, but they are very low impedance compared to most devices. They can be a bit noisy, though it wasn't too much of a problem with the 7520. (more of an issue with IEMs)

Seeing my post again, I did not mean to imply that the 7520 were difficult to drive, just that - as you put it - they scale well as you move to better source components.

The biggest thing I noticed when changing from just connecting the MDR-7520 directly to devices, to using a proper amplifier was the bass response. It seemed to tighten up quite a bit - it's quicker and hits with more impact. It also seems like there is more low-end extension now too - not that I was finding that to be a problem before.

It is strange that there don't seem to be any 7520 measurements anywhere, I guess people just thought they would be the same as the Z1000 because they look very similar.

Yeah, I think that's the main problem right there. There still seems to be a lot of confusion about the Z1000 and 7520, eventhough they sound very different from each other. They're completely different headphones, except for the looks.

Of course, it's an incredible song and that guitar solo is in my top 5 favourite guitar solo's ever, but geez, simply incredible. And the level of detail in there, amazing :)

 

Did you find there was just a bit too much bass?

 

I actually prefer the solo on "High Hopes" from The Division Bell.

To those that have heard bothe the 1R and the 7520, is the bass extension in the same class or does the 7520 delve deeper? Not quantity, but quality and extension.

+1 on High Hopes. I love that song.

If you read the comments made by Tyll Hertsens on the Sony MDR-1R I was given the impression that the MDR-!R is prone to overloading at high listening levels the mid-bass and the forward upper-mids became overpowering. Looking at the specs for the Sony MDR-1R it has Driver Unit size of 40 mm,  a Sensitivity of  105 dB/mW and a power Handling Capacity of 1500 mW

My MDR-7520 has a driver size of 50.0mm, a sensitivity of 108dB and a power Handling Capacity of 4,000mW. That is quite a difference and the MDR-7520 has extremely large dynamic power range. In my book that usually means lower distortion and good transit peak response. I believe that may be part of the reason that the MDR-7520 has great clarity and easy to pick out the parts in complex music.

Well, I just thickened the pads with cotton balls along the inside of the cups. While it did extend the space inside the cup and allow my ear to "breathe", it sounds pushed the bass into "boomy" territory and also made both the mids and highs edgier. It's an easy experiment, YMMV.

The bass extension of the 7520 delves deeper and is of much better quality than the 1R. Either way, they're completely different headphones in terms of sound signature, with IMO the 7520 besting the 1R in every way. Or to put it differently, the 1R doesn't even come close :)

The 7520 bass goes deeper and has more presence. The 1R is tighter and more clear but less extended......a classic tradeoff. The 7520 is smoother across the rest of the spectrum.

I love the 1R and even owned it for a time, but when directly A/B'ing against the 7520. It just loses. Not badly, but it still loses in almost every category, including bass extension.

^what about soundstage width

 

for that matter how does its soundstage width fair against most closed backs?

Sound stage sucks. But it's not as bad as the Z1000. I find the width "acceptable" at best. Imaging and instrument seperation is however pretty good.

 

On a personnel note. I don't find soundstage width to be important at all for me. If I can have it for free, yeah I'll take it; but I won't look for in headphone at all.

post #120 of 2340

I used to hold the same position on soundstage. My thing was bass and then when I found everything I wanted in the lcd2... I wanted a little more soundstage. That desire snuck up on me. I am becoming wayyyy too picky.

 

all of it started with me trying to find a good headphone for vocals under 200
