Lower treble spike is surely there, Sonove's graph, Tyll Hertsens and Golden Ear's all show it. GE uses the standard hybrid tips as does Tyll, if anything, wider bore tips will probably make it worse. Foam tips will actually help though as long as there isn't too much of it past the sound tube. GE usually graphs with different tips and there is quite a difference in the treble with certain ones, but spikes don't go away, they just get tamed  with certain tips.
 
It's relative to our sensitivities and IEMs of use as well. The EX600 wasn't as harsh when I was using the FX500 and HJE900, but when I started using the Xcape IE and GR07 the spike became more apparent.

 
Right!
 
So James, what is the FR graph at the end of this page actually telling us, about the difference in sound between EX700 and EX1000? -http://sonove.angry.jp/sony_MDR_EX1000.html

Hey, I'm not denying that there are spikes on graphs. In fact I held back from buying the EX1000 for several months in the first place, because of these graphs. But when I actually had them and listened to them, I simply didn't experience the sibilance or harshness that was to be expected from the graphs. And neither did dfkt, nor several other fellow head-fiers.
 
Quoting from the conclusion of my original review: "To the contrary, with my tips and to my ears the Sony's treble is amongst the most forgiving and refined I've ever heard."
 
Again, I'm not doubting the spikes on graphs, but for some of us they simply don't correspond to our listening experience, so go figure.

Seems to me that a majority of IEM's that are considered airy, bright or with sparkle have a spike between 6k and 8k.  Then those IEM's that are considered to have non-fatiguing treble, like the W4 or UM customs move their spike to 10k and everything between 6k and 8k is much lower.  This is just a broad generalization based on what I've noticed.  In the end, I like to find out for myself.
 
I myself never had a problem with the eX1000 treble either.  It's very airy sounding to me and helped to provide the best soundstage I've heard so far in an IEM.  The closest treble to the ex1000 I've heard was the UE TF10.

Like the CK10.

but it's more enhanced than EX700 treble, which was horrible, so someone must be at fault here.

The EX600/1000 soundspace is very good, it's a shame we don't have graphs to calculate that, and have to rely on the written word.
 
 

What is your problem?  Are you trying to be confrontational and annoying? If so, you have succeeded.

No, the EX700's spike is worse and it has a more enhanced (albeit in a poor way) treble. Compare it to the EX1000 here. 
 
 
EX700                                                                                                      EX1000

 
EX700s seem to have some nasty resonants in it's treble. 

 
Hm? I am just saying the FR graphs don't tell the whole story that's all, and using examples...
 
 
I'm not confronting your opinion, I'm just pointing out that the ER-4 is quite bright, sparkly and airy, and yet it's flat between 6kHz-8kHz, I'm confronting FR graphs not you, I just wanted to make people aware that they don't tell the whole story.
 
James said he was skeptical about the EX1000 via looking at the EX700 versus EX1000 graph, I've seen other people say that too, the point is the EX700 sound very different, and the EX1000 has nicer treble.
 
On the other hand, I don't think the harshness in the EX700 is coming from the treble at all, I think it's coming from the mids, so there might be some confusion there, when looking at the FR graph of the EX700.
 
I admire those that measure IEM's and users like Inks that try to analyze them, it's just difficult to analyse sound, that's all, but it is fun. )
 
 
Edit: Now that I think about it, I was skeptical of the new EX series too, I didn't want to own the EX600/1000 at the same time as EX700, thinking they'd sound too similiar, that wasn't the case.

Nice find!
 
Have you ever used the EX700? I tend to think it sounds nicer when lowering 1kHz a few dB... so I think there is something happening there too, which might show up in an IMD graph or something like that.
 

The resonants are in it's mids as well, it's higher mids. I think the EX600 is harsher than the EX1000 as well. Haven't used the EX700 and not interested at all. 

Probably the fairest way to measure would be with their own tips in a volume similar to a canal. That sony looks OK to me.

Yup, I remember that guy, wonder what he's up to.  Probably busy purifying his crystals.  

  
 
I will say when I pick tips, I choose tips that let the bore breathe, I want to get the full picture of what a driver is doing.  I rarely if ever use tips to attenuate FR but if one were to do so they could find many phones can be much more rewarding and pleasing.  There are however measurements that show the lower treble bump.

Yep those famous graphs that so many headfiers see as religion itself rflmao. But seriously I could clearly hear this treble spike and its nasty. No matter the tips, I even used a makeshift tip such as james to fill my ear canal super tight fit and that didn't fix the issue. I'm glad you folks can't hear what I hear otherwise we'd see a lot more of these EX1000s in the for sale forum, or in the garbage (joke).

Yep I found using tips with a wider bore to increase the sibilance on them. The extra large hybrid tip combined with a large double flange from the IE8 is what helped me to get a good seal.

My two-cents>>> Get the 7550.... Sibilance problem solved. The end....lol. 

The spike seems to be the nature of the driver. The spikes aren't that bad though, nothing like ones by the HJE900 or Q-Jays. Foam tips and possible smaller bore tips may make a good difference due to their nature in taming the whole treble region, check out how the EQ7 changes for the better which has a spike of similar altitude. 
 
EQ-7 with supplied silicone tips                                                      EQ-7 with supplied Comply tips.

 
I think gain is an important factor to consider. Haven't heard it much but the treble spikes weren't a problem until I had to turn the volume higher due to a lack of isolation and more outside noise. Like the FX700, I think these Sonys are more of a in-house relatively quiet setting use IEM. FX700's bass becomes too much in louder settings, same with the EX1000 happens with it's treble. 7550s do seem to do better in this aspect, it's treble seems to be in a Shure-like fashion, but you'll lack the air of the EX1000s. This does make the 7550s more versatile (though less "special"), been interesting in trying these because of that.
