To the people that have custom IEM, I have some questions:
1) How much isolation do you get with a proper fit? Are you able to clearly hear people next to you talk? If you walk around on the street, are the noises all very dim or just slightly dim?
I tried my JH13 for a week and it seems the isolation varies greatly between the type of sound that's around me. If someone stands in front of me and talk to me, I can hear them clearly. Sometimes even standing several feet away I can hear people's voice clearly. But sounds like plane engine are greatly reduced.
2) Is it normal to have the faceplate of the CIEM not vertical to the ground after I insert it?
The left size of my JH13 has the faceplate at an angle after I insert it. The fit is good I suppose, not pushing against anything but I'm always reminded of their presence so it's not ultra comfortable. The angled insertion makes it quite hard to take the left side out since I can't just twist it.
As far as the sound of the JH13, I like it and a pretty good improvement from what I had. I just went to a conference where they had some really nice subwoofer putting out massive bass, and the sound of the the stick hitting the drum from the speaker is so real I don't think any IEM can even touch it. Every time the bass hit, I felt like I was the drum with both my ear drum and the air in my lungs vibrating.
