The good news is you can put a barbell on the opposite to bring stability. LOVED for years! I purchased 6 pair for friends at a ladies retreat and the slippers were a welcome surprise. I prefer male vocal on the hd600 because it sounds fuller, and I prefer female vocal on the Ety because it sounds sweeter. Im 6 tall, and it fits for any exercises I do. Will not buy again I can feel when someone is in front of me to the right. Quizá sea un poco caro (tampoco exagerado) pero valió la pena, pase toda mi información del celular a la memoria y la velocidad de escritura es un 10/10, fueron casi 50gb de datos y en menos de 5 min ya mi cel había quedado limpio. I am not sure if my beard is growing because of these products, but I know it is doing just that. They tend to slip a bit on my feet when walking and cause a drag on any carpet.
