Oh no, I didn't mean it to sound as if I don't believe your readings. I do believe it, I just can't believe that my ears can't pick that up.... I AM getting old though.. haha

Sorry, I didn't mean my reply to imply that. I just got my rig setup a short time ago so I can't be sure my measurements are up to par, so introducing another measurement was just a double check to my own measurement. @o0genesis0o even mentioned he thought my measurement was probably more representative than his, so that was a good confirmation that my rig is setup properly. All is good.

I haven't tried Huayunxin CNT can you give an impressionon them?

I am still playing with the combinations but it sounds very smooth, zero peak, no sibilance and extended, also very resolving. The lower mids and bass depends a lot on the shell so I need to find out what it is capable of.

I can relate to that to some extent I tried many foam covers and it really depends on how the sound reacts to it that's why I mod them add holes and such to improve sound quality
I really like fiio foam cover because it doesn't affect SQ that much you can also try using silicon rings and wings as replacement to foam covers
Main reason I prefer using earbuds with foams because is it helps create a better "seal" between the ears and the driver as it bridges the gap between them

Yea, I agree with the seal, but I think foam, by nature, as a network structure, disrupts the the sound by alteration of the sound paths and the amplitude so just IMO it cannot be overcome. I think it should be a better idea to make rings out of better silicone material (the ones in the market are all too stiff IMO).

The mass that design needs to move to produce sound pressure waves vs just a light weight diaphragm and vc wire seems counterintuitive.

Yea, so I wonder if it is possible to have a passive circuit to make the DD and the shaker be seen as driven by two identical but separte sources.

There's nothing wrong with not using foams. The early Apple (flat head) Earbuds were designed / tuned to be used without foams. Some of the buds from the '90s were also like that. If you have a good fit and the tuning is alright for you, then that's all that matters. Most commercially available buds are tuned in such a way that foams are required for best sound or they don’t sound right. Since you'll be making your own, then tune them so they sound perfect for you without using foams.

Exactly, I think most buds are tuned with foams, and that's why I don't think I am buying anymore aftermarket buds. I bought a few buds and not too long after that (well, it's less than a month since I received my first buds in years, lol) I have decided to DIY.

I can't tell you exactly what the specs are for this driver, but it appears to be this one, and either @saldsald or @jeejack would be able to tell you more about it (and I suspect more DIYers could as well).

I asked wheather it is this driver and @jeejack said yes:

Interesting fact:
The Chinese name of Qigom is 轻歌曼
and Yinman's is 龙谣音曼

I think 曼 is not a very commonly used word and I speculate that Yinman maybe related to Qigom?

looks like the FF5 is more boosted in the upper mids.

Interesting, I do not hear this boost but I do on the RW3000. Anyway, the main problem for me is not the upper mids.
Some instruments sound thin in the lower mids area. FF5 sounds fuller, close to my TOTL planars.

 

[droenald]

Strange, can:t delete the double post...

 

[droenald]

For what it's worth... looks like the FF5 is more boosted in the upper mids. Though both have different sound signatur

Looking at the graph I would think, that the RW3000 sounds probably both slightly "tinnier" with harder hitting snare drum (early rise in pinna gain starting at 1000 hz) as well as more detailed than the ff5 as it has about 2db more energy in between 6 and 9k. Quite the difference there. Where the presence region of voices are around 3-3.5khz the ff5 has more energy. This is where rw3000 has a dip. Probably thats why people say "never shouty" about rw3000. Judging only by the graph I'd be guessing the ff5 is the more correct/real sounding bud...

Yes, also have found some buds are better for me without foams (say, Yincrow X6).

 

[Kenyon]

Earbud graphing guru @Ronion always suggested to align somewhere between 100 and 500Hz. This is probably more realistic now.

Better to align at those frequencies as there is no substantial pinna/ear gain issue so can potentially apply to a wider range of people. (Bear in mind the first graph was conducted at a 45degree tilt which is not properly representative of how buds may be positioned or used. You can see the effect of directionality on the second (set) of graphs.)

Also most people hear lower/midrange frequencies similarly - deviation really starts above 4khz. Second set of graphs shows the individual differences between a group of people - (thanks @RikudouGoku for providing this elsewhere)

The PS100-500 sounds surprisingly awesome from the Mojo2. Now listening Tool's Fear Inoculum. Justin Chancellor bass.

I see you have some very high end buds. How would you rank the PS100–500 and the PS100–600? And how would you compare these two? Is it just that the PS 100 –600 has more subbass, or is there more to it than that?

Here you have some early thoughts.

I really don't like to make rankings but definitely they are TOTL earbuds. Crazy to think they were released years ago.

Why do you cut it assymetrically?

And what do you use to cut it?
I have ff3 , I will try to cut to the most outter diameter.
Even donut foam, the sound muddy a lot. Seems like the bass reverb back if no air out

Very helpful impressions! It's a little crazy how we all seem to jump on some of the same earbuds, and other TOTLs get lost in the crowd. Would you say the PS100-600 is a side-grade to the Yinman 600s -- that is, not so "necessary" (whatever that might mean) if you have the Yinmans?

I'm cutting them asymmetrically because the positioning and size of the hole change how earbuds sound significantly. It helps preserve details that otherwise would be muffled or lost by being covered by foam.

I use both leather punches and rotating leather punches.

If you plan on doing this, I recommend placing paper under the foam for a cleaner cut.

The Yinman has better not weight and dynamics. Also sounds warmer. Both benefit from a powerful source that definitely brings out more details and an wider soundstage.
