Tricky in the sense that I think the planar is offering a smooth refined quality mid so to 'boost' that...?
The nearest Ive come to a balanced sound is Pink lower and gold or red top..although Im using pink bottom and blue top at the moment
TBH. although the bass is awesome, I wish I could tune a more balanced sound over all especially in that its quite a full sound as is
I love the low end...its pretty incredible...but its usually always there...like switching on the bass boost button on an amp and frankly I can find it tiring...if Im tired!
Anything in a mix that always makes itself known..no matter how qualified the quality of it is has the potential to be fatiguing after a while
Having said that I haven't run the gamut of different tips yet
EDIT: of course as soon as I write this I find some tips that take off just enough low end to make them a tad more balanced ! o_0 . . . I think KZ stars
