I suspect that is where the problem is. Many thanks! La instalación fue muy fácil, los auriculares funcionaban también muy bien, y estéticamente eran muy bonitos. I ordered the standard pillows a few months ago and really liked them so I just purchased the King size pillows. Nice big surprise was the shape of the zipper pull - it is curved and made it easier to hold on to versus a flat bar shape like many others. If you are a fan of the Bose signature sound, then you will not be disappointed. I am so happy I just may order another pair! Edit: unfortunately after a month or so my heavy has ripped. At first this seemed to play extremely well. I dont know if these were cheap knock offs with similar branding or if the quality has been down graded.
