I always have been reluctant in applying EQ tweaks on IEMs unless it was only the bass that needs adjustment.
With the H300, I pushed myself to do so because I am really curious how these would have sounded without that peak...
Alas! Guys, after days of playing around with parametric EQ I've managed to tame the highs to almost flat and I must say the entire sound presentation is HEAPS better than the stock sound. My initial impression was that the bass and mids were almost perfect for my preference. After tweaking the treble, I am confident that the H300 COULD HAVE BEEN one of the best IEM I've heard along side the Noble 4. I'll even go as far as this could've been better sounding than the 1Plus2 ORIGINAL version.
But that peak... what a shame
So stay tune for my review guys... I'll elaborate more.
Cheers!
