Thats not the only thing knocking. I only had these for about a week but during that week I have used everyday and they are great! I figured I’d keep them because they are quite sturdy. The silver pair seemed to fit the backings better BUT fell off after less than a week and were lost, even with new backings. Las compré únicamente para bañarme aunque el diseño y estilo me agradaron bastante. Für Sennheißer typisch sind die Bässe ohne Equalizer etwas zu stark und dumpf. However, the comfort factor is just okay. Im very careful with my things. I use this yoke and quadrant with Saitek Pro rudder pedals on my Mac Pro 5,1 for X-Plane 10. I absolutely love these products.
