An excellent example of this is here:
Owl City - If My Heart Was a House
Specially on the starting part of the song where you can hear his voice clearly, it sounded so light but full of presence. I know he high passed the vocals like crazy and probably boosted some on the 1.5K to make it sound like airy/radio-ish one. I tried to imitate this but my vocals ended up close to the target sound but it's sounding a bit harsh. Listen here for my attempt at the effect
And here's my EQ with that attempt
His vocals sounded a bit more "laid-back" even on the loud part of the song. How can I achieve something like this with eq?
