Yeah, it happened in my left iem and I already have pretty massive hearing loss in my left ear, so idk how long it took for me to notice the issue. But this was definitely after a few hundred hours of use.
You're almost certainly correct, and I think I have a pair of spare filters from when I bought the reds. I'm on a trip right now, so I'll have to check when I get home.
My initial impression is that the zero 2 has better deep base but slightly recessed high mids. The reds have an overall more...
Hi Mark. You might benefit from including an estimate for how long this survey takes. I wasn't anticipating having to take time to actively listen to things.
Yeah. To be honest I just checked the markings on the battery and googled PN 805080. I found a whole mess of 8mmx50mmx80mm 4000mAh 3.7V batteries, so I think its a semi-standard battery type.
I agree that the elacs are a good option. You will need an amp, but something as simple as an Aiyima A07 (or whatever the current recommended budget amp is) would be fine. I think the genelecs you listed probably won't get loud/deep enough.
