I got these because I live in sandals when it?s warm out and my flatness bottomed ones weren?t cutting it anymore for walking purposes. Id have given it 5stars if the side storage pockets were waterproof. While battery life always degrades over time, I am very pleased with their behavior so far. These beads are horrible. I paid a good chunk of change, but my daughter is happy, and so am I. But it seems to have made some seriously abused Birks look better/shinier, and possibly rebonded some broken cork, so yeah, is good. This however is not a problem if you are listening at safe normal volumes. Andererseits bieten Flugzeuge und Züge heute oft einen USB-Anschluss. Ive jumped between Corsair, Razer, Keystone, Logitech and Hexgears looking for just the right keyboard. This is my 5th pair, first from amazon.
