I'd like to add that if I wear the UERM's very loosely, with the tops of the housings practically falling out of my ears but the bottom portion pushed in, I can wear them comfortably for much, much longer. The signature is definitely growing on me, I just wish that upper peak was slightly tamed.
Hi Shane, I'm wondering if maybe the hot treble on the UERM universal version would have anything to do with fit issues. I recently received my custom UERM and although I agree the treble is energetic I wouldn't call it metallic and sibilance isn't an issue with me. Mind you, I'm known for liking some energy in my top end so maybe my tolerance for treble spikes is better then yours. In your opinion, do you think the universal UERM is overly touchy with proper fit? Everything else you've said about the UERM I pretty much agree with. It would have been nice to have a touch more rumble in the low end but oh well.
