I don't use them on the go, only at home or at the office, but I'll make the test. What kind of music do you usually listen to? What kind of tips are you using? I usually use them with jazz and classic and use a pair of Spiral Dots, smaller size than I have used with other IEMs.
I listen to everything, mainly rock and hiphop, iam using the sonys tips that came with it, i will give spiral dots a try.
I switched from the Sony tips to Spin Fits and it tamed the highs a bit, making the treble more bearable for some songs.
I don't know but spinfits were never my cup of tea, i like spiral dots more but i will give them a try, may be even comply foams and just kill the highs once and for all
If you want to tame the highs, try wide bore tips, like Spiral dots.
i always felt the opposite
