Hello
A new member here, and barging straight on making a new thread. Please be gentle on me
A little background. I work in a high noise environment, 85 - 100+ dB. There's alot of lower frequencies present, not so much in the higher frequencies. I've been stepping up the ladder, from using hearing protection cups with built in radio, pathetic sound quality and noisy radio reception, regular earbuds pressed against solid yellow foam plugs inserted into ear, volume turned up to max to get through the foam, Koss Plug and most recently Sennheiser CX300. All worn under regular hearing protection cups.
As for physical comfort, I find that I can wear foam plugs and Koss Plug in ear all day long without problems. The CX300's rubber irritates my ears slightly.
The real problem I have with CX300, is that they make me really really uncomfortable. There's something constantly present in my head, a rumbling sound that really sort of both tranquilizes and makes me at unrest and stressed out at the same time. After a week of using the CX300 at work I just had to stop. My ears were beginning to hurt, even when I didn't play anything through them, and music sounded just strange.
I thought I was just imagining things, or that the presence of the CX300 and the cable coming out from underneath the cups was creating resonance, or..... well I went back to Plug, though it also annoys me to no end. I wore out my last pair and haven't been able to find a decent new one. There's so much individual variation between them. Replacement pair 1 had right earbud at half the volume of the left. Replacement pair 2 has significantly different frequency response between right and left... sigh.
As I was looking for a replacement, I was looking at headroom's measurements of various IEMs, and noticed something startling on the isolation graph:

What's going on at <30Hz? Is that amplification of the lower frequencies? Maybe I wasn't imagining things afterall...
Now I am slightly curious. What causes this? Has anyone else also experienced this in real life? Is it all bogus and just a side-effect of measurement methodology?
I am considering Shure E4C next, isolation looks excellent, and considering I can wear the Plug's foam tips forever I think I'll love Shure's foam tips
Maybe "excellent" is the wrong word, the isolation looks unbelievably good...
