Looking back, I think people are right with different ear tip changing the experience of the sound.
Personally, I didn't see much difference of using the JVC eartip over the original stock. Yes, there was change but not as much people here had led me to believe.
That said, I must say, for those of you who had been fortunate to have had EPH 100 in the past, I say give the EPH 100 eartips a try to the CKR 9LTD.
The CKR9 LTD with EPH 100 eartips are like on a completely different level of openness (and the soundstage is MUCH bigger).
I understand for most people they will have to stay with JVC eartips (because EPH 100 eartips are never sold separately) but after having tried many other eartips, I think I have found the "perfect" eartips with the CKR9 LTD.
So yea, if you guys have the EPH 100 lying around at home or the EPH 100 eartips, try plugging them to the CKR9 LTD. You will be so surprised the difference in sound. Maybe because the eartips are super long by nature that you get the open space sound. Maybe because the eartips are bendable the sound can directly go to your eardrum.
Though I shall never know, I think what matters is the result of the sound. And I must say, the EPH 100 eartips take the CKR9 LTD to the next level.
**When I say the sound is on a different level, I actually mean it. You know the feeling from going to apple earpods to like your first true audiophile in ears? Ya, that's how dramatic the change of sound is for me. I really have no idea how an eartip can change this much but I have to assume this is mainly because of EPH 100 eartip's super unique design. Personally, I think any long eartip (like EPH 100's biflange eartips) will make the sound have a much bigger soundstage. And in case you are wondering how EPH 100 eartip looks like, .. they look like: http://www.amazon.com/Yamaha-EPH100SL-EPH-100SL-Inner-Ear-Headphone/dp/B00591GIMY/ref=sr_1_1?ie=UTF8&qid=1456795412&sr=8-1&keywords=eph+100
Yes. As you can see, it is not something you really can buy separately as to my knowledge only Yamaha have ever used these eartips and never decided to commercialize it.
That said, sound score wise, I give CKR 9LTD with Yamaha EPH 100 eartips a 9.3/10. And with the JVC, 8.8/10.
Having said that, if you guys don't have the EPH 100 eartips, don't bother buying an EPH 100 for the tips only. That I think is super silly. I am just posting this for people who have the eartips of EPH 100 at home. Just try sticking them in. I use the medium size and have been fortunate to have 2 sets of each (due to warranty).
