The differences I detect using large bore tips are more air In the presentation and open soundstage, when you can measure that let me know.

I think there is an artificial brain option with the test equipment, so results for you should be forthcoming.ph34r.gif

Brace yourself, explanations are surely inbound.

Can someone please explain to me how driver flex happens? It's really an interesting thing. I never had this issue(it's not really an problem though) with any other iems...

I ordered the VModa tips H2O recommended.  The i-Digi I was using started feeling loose and would spin on the nozzle, probably fatigued since they were a few years old or the phones they were taken off of were slightly larger.  Will have to wait a bit though since the H200 are out for repair.  I'm hoping T-Peos will have the SPC cable ready to ship by the time the repair/replacement is finished. 

 

I too am looking forward to what Inks has to report on these, I think there is something to his sense that they're sensitive to insertion depth.

Impressions so far are positive overall so far.  Remind me a lot of the SuperDarts with more controlled bass (something that turned me off from them in the first place).  There is a hint of sibilance in vocals.  Detailing is a aggressive, similar to detailing stylings of an Ety, and clarity is very strong as are vocals.  Midrange is done beautifully except for that slight sibilance.  The dip you see around the 6 kHz isn't as audible as it seems partially due to the resonance at the 4 kHz making up for some of the instrumentals (lower treble) while the 10 kHz makes up a bit for the upper treble.  The formation does lead to more of a metallic sound though that can be a bit sibilant as well (on certain recordings).  That said, the dip is masked quite a bit overall.  That's about all for now. 

I am using the translucent grey tips right now.  I do hear differences between the tips, that's inevitable really.  I'll graph them when I have more time...  For now, it's time to eat. 

EDIT: last note, grey tips were used throughout for measurement.  Smalls were the size that was used (they are the size I use personally). 

EDIT 2: no problems with comfort or fit for me.  I can wear these over the ear fine and the form factor has no problems with me.  The elliptical protrusion on the buds help keep them stable if used properly.  Driver flex, however, does show itself.  It's stronger in my right ear (IEMs tend to seal better with that ear for me for some reason).  So release air pressure as you insert them and you shouldn't have problems. 

EDIT 3: the graph T-Peos has is accurate assuming you are using GoldenEars' compensation.  It highly resembles my graph (same dips and everything).  Since GoldenEars requires a boost in the bass, and mine compensation doesn't, that would be the reasoning for the bass boost. 

EDIT 4: before anyone asks, my measuring system has an early roll off in the bass.  I've created a compensation for it, using Rin's past graphs as a reference (as well as Tyll's), in the colored graphs.  Then use the standard DF compensation.

=) very nice.

Thanks for the work you did with the measurements.  I'm eagerly anticipating Rin's comments and measurements. 

 

Yeah, I was surprised myself too...  I listened and was, where is this difference every one is hearing?!  Where is it XD  Then I measured and was like...  Um...  Yeah...

 

Hopefully Rin can confirm my measurements ;)

If I have the time, I'll do this.  I know Rin will be doing something like this though ;)

Driver flex happens due to air pressure build up.  When you insert an IEM into your ear, you compress the air that's already in your ear by lowering the volume in which it has to take up.  If this air isn't equalized before the seal is completed, then it will press up against the driver of the IEM.  When it does this, little to no sound will be produced by the IEM because it can't move against the air pressure that's against it.  Driver flex can also be heard when inserting the IEM as well, since the air pressure changes cause the driver to crinkle up while inserting it.  It'll uncrinkle though once air pressure equalizes. 

 

So the idea is to equalize the air pressure as you insert them.  This can be done by creating a small hole between the tip and your ear right before you complete the seal, or using different tips.  Softer tips allow more air to escape.

Barely. Probably due to the fact that I used foam tips on my other iems.

Thanks for your explanation. It was a great help.

Since when do H-200's exist on eBay and Amazon?

They've been on amazon for a while. Few months at least.
