I'm not a treble head or a person who likes a lot of treble in the sound, but because of the TWISTURA D-MAJOR, I think I'm becoming one. As long as I use the red nozzle and carefully select my sources, the overall tonality is near neutral but with extra treble goodness. The quality of the driver used in this IEM sounds like it belongs to a more expensive IEM in terms of performance, which is why I can forgive them for including an ordinary cable, as cables are easily replaced.

The TWISTURA D-MAJOR sounds so good that it earned a badge as one of my personal reference IEMs in this price range, and thus earns my high recommendation.
