I am very satisfied with the device, despite EU directives, I find the volume well. The sound is great, because Sony has developed a fine device. In sports, the plugs do not fall out of your ears. In addition, no more spaghetti wires. For swimming I have not tried it, but I suspect that it will work well, because the ear is well sealed by the plugs. Of course we hear generally less of its environment, but that's purpose when you hear music I find. The service is super easy if you have the device used a few times. The Walkman tells you if you play or shuffle pressing or pretending the volume. At various beeps you can hear if you continue on a song. The bad reviews I can not really understand so actually. Who likes to do sports and hates clutter, is well equipped with this device.
