So far they are very sturdy. Sad to say, Ive learned my lesson. I like the color of both of these shirts and the fabric, and Im sure it would be great for someone whos got tighter abs, but for a large, it fits a little tight around the middle and doesnt hide my tummy the way I like. I bought this one for my grandson whos American sandals is 11, but was azlittle to small so I returned and got a size 13 for havaianas and fits perfect. ¿Cuáles son los puntos débiles del sonido? Bien, en mi opinión la espacialidad es pobre; difícilmente se puede percibir el sonido más allá de tus orejas (a diferencia de los DT770, DT1990, T50RP e inclusive los HD598, o los SHP9500, entre otros). I cant afford a fall, so I pulled the tattered layer off and checked the other slipper. Ive had some good headphones from the likes of AKG, Grado and Sennheiser and Ive noticed that all manufacturers have their distinctive sonic stamp. I would highly recommend purchasing this beer bong. I bought these for my husband for Christmas and he LOVED them. The sound is good.
