Even at a healthy volume, the sound quality is stunning; classical music at normal volume is incredible! Im using these water shoes on a jet ski. Yes, I did put it in correctly. Durability:I have recently bought the Philips, so I am yet to see how long it lasts. Sound quality is amazing for ~$100 headphones. En cuanto a comodidad son muy buenos, si bien después de un par de horas de uso sientes la necesidad de retirarlos de tu cabeza para descansar un poco, creo yo que es algo normal, como traer una gorra o algo por el estilo. The on/off toggle switch is one of the nicest features many more expensive, name brand headphones dont have. It last me 3 month. I have had these for almost 2 years. My wife likes the way the slippers look.
