What are low impedance headphones? Are most cheap headphones low impedance? Will I be satisfied with the Lumia's audio quality? I don't have particularly high standards, and the most expensive headphones I will use are 10 dollars.
Also, I think that my iPod Nano 2G, iPod Classic 6G, and Clip+ all sound just fine. I know that the iPod Nano 2G especially isn't particularly known for its sound quality. I know the Clip+ is known for its sound quality, but I don't really notice a significant difference between the two. Will I be satisfied by the Lumia?
