Purchased these to enable background music whilst outside gardening or having a BBQ. They give a solid, coherent sound which is easy to listen to, and the volume is loud enough to cover other background noises and is of a reasonably good quality at low to mid / high volume. They seem sturdily built, and have a reasonable weight to them. I use them with an iPod touch with music stored as AIFF files.
A good buy to have as an outdoor solution without having to 'wire up' the back yard....
