Headphoneus Supremus
Right the bore size is only 1 aspect / 1 part of big portion that affecting sounds. Material also affecting lot, then the shape of the umbrella and insertion depth, nozzle length also affecting the sound.
Generally small bores eartips will reduce 4-7khz area, with 5-6khz area affected the most. So this will reduce lower trebles thus will lead to resolution and the balance with lower end (will perceived as bigger bass because of actually reduced treble, also at the same time make the "bass tube" through the eartips smaller that leads to more higher pressure of mid bass.
While wide bores eartips as oppose to the former, will increase 4-7khz area with 5-6khz area affected the most, higher resolution, more detailed lower trebles and reduce bloated bass (aka reduced mid bass) with same sub bass.
then materials like foam absorb the trails, or muffled the resonance that leads to upper treble reduce. so foam with small bore and foam with wide bore will sounded different too. Even silicone, hard silicone, soft silicone, rubbery like silicone also affect difference resonances.
This can be measured as impulse response. and mostly are inline with what I'm hearing
See the middle left like edge of the leaf thingy, the harder material, they will shaped like rough zigzag lines (on original spiral dot), so the material is harder, they will resonance the edge more edgy, plus points is sharper mid bass, minimum smears, with more edgier or detailed micro details transients. Then the overall bushes like lines to the right are the macro dynamics, Original spiral dot have more macro dynamics, contrast resonance.
Compare with the lower impulse response of Spiral Dot ++ that made from softer and more rubbery like materials. The edge of the leaf thingy (left, mid) is more smoothen of, this will sounded less edgy, soften presentation, then to the right the macrodynamics are still there but less than original spiral dot. Can be plus or minus depends on what IEM you're going to pair with. To tame edgy and bright IEMs, the spiral dot++ is better. It's all about pairing ecosystem.
Same goes with dampening IEMs, if the manufacturer think deeply, they will have great match for their driver setup and tuning. But mostly, they never think this deep, just put the common nylon filter on the nozzle to chase the target that given by someone, or the collab partner.
I agree, just save and upgrade to IE600, IMHO the IE600 is the best among Senn's modern IE line ups. Even with IE900, I feel the IE600 have better tuning, and more value than the flagship.
Measurabation is strong with this one
And how about a teaser of.. umm, limited IEMs with :
-non bleeding bass, tight and impactful with 2DDs
-tribrid multidriver setup (many drivers) with great extension end to end
-non shouty mids, safe pinna gain but non recessed mids
-lot of dynamics
-properly dampened, with good airflow
-airy and detailed trebles
-priced below $170?
!!warning : need juice to drive these!!
That 1.5kHz scares me
The whole graph reminds me of certain multi-kilobuck but I can’t quite put my fingers on it. That 1.5Khz is reminiscent of the VE EXT to a degree. That 8k region also raises questions. But who knows, maybe everything would just click together into an interesting signature.
How hard to drive are we talking about? Btr5 via balanced output or portable amp only?
