I bought these earphones based on some positive reviews I read elsewhere. After burning in, I have to say that I am amazed by the details these earphones can deliver. It offers a dynamic sound experience, the bass is punchy, and it does not over-power the mids and highs, the mids are perfect with super details, the highs are crisp and the sound stage is just like any full-sized headphones. Once it's properly worn over your ears, you can listen for hours without fatigue. I'm very happy with this purchase.
