Alclair CMVK here. Quite a bit different than my old Shure SE425s. I like them, and would do customs again. Great isolation and tons of low end. I can keep my volume low and not get fatigued with them in. I might go for a flatter model next time just to be able to compare, but I'm happy. Alclair came to the church I used to play at (they do a roadshow thing) and did my impressions then (for free). Thought about it for a while and then waited for a sale and ordered.
