Replacement Audio 2.5mm to 3.5mm Cable Compatible Bose QuietComfort 25 QC25 Headphones with Mic and Volume Control (Black)

Though it has the proper size audio jack, the black plastic surrounding the headphone jack doe not fit all the way into the headphone so you don't get both ears working. AND They charged me $5.99 to return the item even though I have PRIME. Very annoyed.

The item doesn't fit the Bose headphones.
