Carrying Case for Bose QC2, QC15 and AE2 Headphones Important: Most all new headphones are sold with a carrying case included. Only buy this case as a replacement for the original case. This carrying case has a water resistant zipper with fabric covering the zipper seam. For that reason the zipper on this case will be stiffer than others. Candle wax or lip balm makes a very good zipper lubricant. There is also a very good commercial lubricant by McNett that can be located by doing a search for B000GKFCUW. Great protection for your expensive headphones. Sturdy shoulder strap External elastic pouch for more storage.
