I want to get your opinion abt good aftermarket earphone that cost reasonable how they measure up against the iphone earphones. I tried a few that are in the $35-$65. I tested a few brands I went to a shop that carries a wide variety of product lines. First I set my iphone sound to "flat". Then I begin testing different earphones and play a same song. After 1 minute I swithed back to iphone earphones and I repeated this on a few brands. I honestly think the iphone sound better than the others, sound more vibrant in almost all frequencies. Have you done a similar test? In summary, no need to buy an expensive aftermarket.
