Sony MDR-7520 - Page 41

post #601 of 2340

sorry my meaningless post has been deleted.  Since we all have different ears, perception is quite individual therefore ones neutral may be anothers slightly tipped.

That's a brilliant theory. I'll have to check it out under good lighting. I do have a nice air blower I use to clean the sensor of my DSLR. So maybe I can use that on the port to see if that clears it up. But I'm pretty happy about the bass at this point. It's very "neutral" from my subjective perspective and there is a perfect balance between the mids, high, and bass now. No infringement or overbearence. But I must have logged hundreds of hours on the thing too, so it might just be the LCP breaking in. It's not mylar so it's hard to say how it'll react over the long run.

I believe that the bass port does have some sort of a plastic divider or shield and not just a plain open hole.

But not like the MDR-7520, then, or am I missing something? The Sony's supposed to be useable for mixing/mastering (to translate very well to near-field monitors).

That would make for weak-in-the-bass mixes.

 

Oh, so confusing....

That just completely echoes my experience, I was quite overwhelmed by bass out of the box, now do not find it out of ordinary at all, even when directly comparing to non bassy phones. :confused:

Whether it's drivers or brain burn in, I just love the result.

I do agree that the bass has tightened up and mellowed out significantly over time, but I haven't listened much for the past week, been very busy with other things. Next month I'll have a sh*tload of freetime on my hands though, when I'll go back to listening to a lot of music :)

That's what I have also previously always thought. I don't claim to speak with any authority on this, quite the opposite in fact, but it seems to me that monitors (near field and full size) should ideally be flat because the acoustics of the room they are in, even control booths in recording studios, will introduce some degree of interaction and roll off, but when you strap transducers directly over your ears the perceived FR will be different, so a headphone with a flat FR will sound different from a monitor with a flat FR (according to the acoustics of the room which it's in). I'm wondering therefore how 'neutral and natural' a hp with a flat FR would be. In the end though we're talking about the reproduction of recorded music and of course there are so many variables along the way that I think that if the result is pleasing, that's all that matters. My only question is whether monitors and headphones should aim for the same ideal when it comes to FR. Personally I think not - at least in the case of closed hp's.

Joking aside, I have my own understanding of the term (mainly derived from the measurement standards referred to in this post), but I'm fine with everyone else's personal take on it. Just disregard my "neutral" remark if your understanding happens to be different from mine, the comparisons to other phones I've given may still be useful for some readers.

 

Thanks James. I had a feeling that the subject may have been touched on before.............

 

And thanks for the interesting link. IMO the 7520's bass is somewhat north of what I consider neutral as well, but, as stated earlier in this thread, it seems that people who mix on them find that the decisions they make regarding the bass translate very well to other systems. I think though that monitors and hp's follow (or perhaps should follow) different rules (see my previous post).

I also agree about the bass tightening and becoming less prominent in time. 

 

This may be just me, but I find the bass impact to be dependent on the amp. 7520's bass is quite polite on a lot of songs from my phone; has a little more impact from my computer; and was quite impactful from a Benchmark DAC1. With the benchmark, I was comparing the 7520 to a K701 and a DT880, and the 7520 has quite a bit more bass impact than those 2 cans, so my impression may have been a bit skewed there.

Yeah the bass might be system dependant. I'm using the Fiio X3 for the moment.

 

So I was listening to my LCD-2/HE-500 combo last night and decided to see where the 7520 bass was. It's about the same amount as the HE-500, but definitely weaker than the LCD-2. The balance between the mids/highs/bass is also very similar to the HE-500, which is my personal reference for "neutral" headphone. The only thing though was that the 7520 was a bit more uneven from the mids to the highest highs, and also the transition from the mid-bass to low-mids was a bit rough/uneven, but still fairly flat. The HE-500 is ridiculously flat and smooth from top to bottom.

 

So yeah the bass calms down after awhile and is weaker than the LCD-2 for sure. And the extension is surprisingly good for a small/closed headphone. The big dawgs win of course but the 7520 goes down swinging hard, and not just in bass but in nearly every category. It's definitely "good enough" on the go for me. Given how light it is and how it can be driven from something simple like the X3. I'm planning on switching to the X5 as soon as that becomes available and I'll let you guys know if there are any changes to the bass.

Yes, good points. I have always maintained that if you know your gear, know where it deviates from flat, know how stuff should sound through it, that's all you need for recording and mixing purposes. If you start off with stuff that has relatively flat frequency balance, it just makes it a bit easier.

Amplitude vs Frequency is only half the story of a (linear) time series response…does anyone also measure Phase Shift vs. Frequency? Also, does anyone measure non-linear responses (e.g., interference between different frequencies)?

I think this is a good point

Also, does anyone measure the effect of these parameters on perceived SQ?

The waterfall plot on the headphone would be a good source of information. That will tell you not only the decay times in the headphones but will show the peaks in the frequency response. It can also gives a good idea on how tight and clear the bass response. Once you get the hang on reading the waterfall plot you can correlate what you hear with the plot.
