Hard to describe but I'll try (apols in advance). Maybe a bit of a dramatic metaphor, but when I'm listen to something with the kick that - say this (
Spotify link) introduces at 2:59 - there's that extra level of sensation beyond just what you can hear. The CL2 excels at this (imho) because it can provide this without the losing anything else. A bit reductive, but one track I use quite often is Burn the Witch (
Spotify link); has those urgent, eery violins at the same time as this momentous, energetic bass riff. CL2 nails doing both of those at once. Again, you'd need to hear it to really see what I mean (again, sorry - are you at RMAF?) but I hope that makes some kind of sense.
We use dB/mW to measure; I'll clarify that on the web page (thanks).
Preach! Makes an enormous difference when you get the fit right. I have a medium right ear, large left so it took me a while to get a proper fit with in-ears all those years ago, but the difference was instant.
Cheers,
