Listening to the Sonys now with my usual diet of rock and metal. They’re certainly pleasant enough to my ears, but I doubt the Technics would disappoint either. You can find a bit of info on both earbuds on rtings if you haven’t seen their analysis. They mention the Sony’s memory foam tips, and I do personally like the fit, though YMMV there.
As far as the source goes, there’s probably not a lot of real room for sound quality improvement unless maybe you went for high definition files, and even then I wouldn’t hold my breath waiting for night and day differences. As convenience goes, a phone is pretty hard to beat.
