Q&A:
Q: How is it justified calling the sound delivered by j-phonic ear-monitors "super sound"?
A: We selected two balanced armature drivers that are used worldwide for professional use and fine-tuned the sound curve coming out of the plastic shell. Our sound curves have impressed and satisfied many top professionals and have amazed audiophiles who couldn’t believe the sound came from a dual driver earphone. In the end, it is not the numbers of drivers, but the balanced output of the combined speakers that makes all the difference.
Q: Why are there two versions - with two different sound signatures?
A: For many, sound is about preference. Professional monitoring normally requires flat, high resolution that can be used as a reference. We can liken it to a white canvass that is ready for paint to be applied. The SP (stage performance) version does just that, but with good sound. It is also good for music listeners who often care more about high resolution and clarity. On the other hand, MX (music extreme) has rounded off some of the high end peaks, giving a bit more presence to the low end-relatively speaking. This results in a more acoustic effect to the overall sound, harmonizing all the instruments, and allowing users to listen for longer periods.
Q: Can the "sound signature - be changed after the purchase - from sp to mx or the other way around?
A: Sorry, neither is possible.
Q: Wouldn’t j-phonic ear-monitors be inferior to full custom-made ear-monitors in terms of isolation?
A: Not necessarily so. It depends on the individual’s ear. So far, we have not had any beta-tester or customer who has complained about the level of seal relative to the custom-made. The Comply tips work really well on our earphones. That said, some people who even have gaps with the L-size foam tips may find custom earphones better
Q: So, j-phonic fits 85% of Japanese ears. What does that mean?
A: We studied impressions of 1,200 people; that is 2,400 ears). The figure of 85% is particularly significant when you consider the large number of people who gave up on canal phones. We can strongly recommended the use j-phonic earphones by women with smaller ears. And being able to fit smaller ears still allows j-phonic ear monitors to fit larger ones as well.
