I have the Head-Direct RE2s and they make way too much noise for me to enjoy them. I need to make a conscious effort to stay perfectly still to avoid getting unwanted sound. How do I tell if it is occlusion or microphonics? I get noise when I tap my cable, but I also get noise when my cables aren't touching anything and I just twitch my head. If seal matters, I feel like I'm getting a good one. When I remove them, I can hear the suction, and when listening, it doesn't sound bass deficient. I'm using the large clear bi-flanges.
Do different IEMs have different levels of occlusion, or is it entirely (or mostly) dependent on tips and deep insertion.
Also... I'm hearing my heart beat when listening in bed. I set my Clip between 1-5 volume. Any way to prevent this?
