Is the Type 1 filter the standard filter hte M2s Pro shells come with? I switched the Super One into my old M2s Pro shells where I didn't remove the filter and it has grown on me. I gave it the new Fiio LC-RC cable as well. Because the fit is so good when worn over ear with the new cable, I find myself listening to it more than even the Bell Ti Plus. It definitely doesn't beat it in any regard, but it has grown on me. It's really enjoyable. I think the brighter response just makes things sound a bit more lively and detailed. Bass is just as good as the other drivers. One interesting thing is vocal presentation: I thought the mids were 'recessed' in terms of volume but I think it's more about their spatial positioning. The vocals on M2s Pro Super One sound like they're in my head, which may or may not be your cup of tea. LBBS they sound in front of me, and 150 ohm golden driver M2S Pro sound laid back, like almost behind me.
Maybe I was too quick to write off the Super One, maybe it just takes some time to get used to, maybe people need to experiment rolling filters and foams and cables and wear positions.. but overall I would recommend them. Just note the value isn't quite as good as stock m2s pro or LBBS. But it's a hell of a lot better than the actual Super One model at $300.
