Query: Superb for the price

These headphones work very well, especially for the price. The sound is very good and the design of the different sized in-ear buds helps with noise cancellation compared with headphones that just sit on the ear. As such, volume does not need to be high on your device to drown out crowd noise. They did not feel invasive, and after 3+ hours straight, 7+ hours on some days total, they did not hurt my ears like the "stock" ipod in-ear buds did after only a short while. And, surprisingly, they stayed in my ears without any problems, a concern when I was ordering them.
