I bought these earphones hoping that they would be a good replacement for my existing earphones that came with my iPod clone. I have always had problems keeping 'in-the-ear' earphones wedged in my ear as they frequently drop out. Unfortunately I have the same problem with this model. The sound seems to be ok, but there is a noticeable lack of bass compared to other phones (even after playing with the EQ settings on the player). The built in volume slider is very convenient and is the only redeeming feature. If your ears are a non-standard shape then think twice before buying, but otherwise a reasonably good buy for the price.
