but these dont feel as good quality as mine did. If you get those headphones, you have to get this I stead of the little pouch that they come with. Basically neither slipper will work unfortunately I have to return them both. Replacing the old with these replacements is easy enough to do but the left side took more work than the right - there was so much glue residue on the left side that it took at least 20 minutes to get it all off but it was well worth it. I purchased these in an attempt to join the 21st technology. NOTHING TO DO WITH THE SELLER. I decided to look for a used Bose QuietComfort 15 & found one on Amazon. Como era de esperarse, en las portátiles el volumen no es muy alto, pero aún así es suficiente para que esto no represente problema alguno. The circumstances of the main body is too big and the inserts do not stick out far enough. Fortunate I found the right size and different color, other than the black or greenish.
