La diferencia está en cómo nos ponemos los auriculares, los Sennheiser tengo que medir al milímetro cómo ponérmelos para que no me causen fatiga, mientras que los Sony me los puedo poner según caigan. Inside material is not sticky but has no slide to it! I compared the TR3?s with a set of wired over the ear AKG studio headphones. Der Schuh ist zwar zu lang aber viel zu eng. Love this shirt looks exactly like the picture. The shoe is absolutely beautiful, it fits true to size. These earbuds are very nice quality. I set the nozzle on wide angle, and boom, here comes the juice. This is best stand for my efatty. Not this device, it has to be special.
