Sony NW-HD5 stock earbuds vs. Shure E2c - HUGE difference? ...well, will there be a clearly noticeable difference in sound quality? I'm thinking of getting the Shure E2c ones but I wont spend any more money right now if there wouldnt be a considerable improvement. I'm not an audiophile in any way but, will I be able to notice a clear difference? Could you try and quantify the sound quality gap betwen the two headphones? Is it worth spending the money? Are there any other similar in-ear isolating earphones you would recommend? Thanks you.
