WC Freeze QC Ultra - Cooling Gel Ear Pads for Bose Quietcomfort Ultra Headphones Made By Wicked Cushions | Breathable Sports Fabric, Cooling Gel, Extra Thick & Cooler for Longer | Black

MUCH better than Bose's stock ones (which seem engineered to fail after 3 months). I don't know what kind of magic material they're made of, but they genuinely do feel cool on the head, which is great for someone that runs quite hot. The thicker material here actually provides better passive noise cancellation than the stock earcups, and ANC and audio quality don't sound much changed. Installation was easy, came with a QR code for video instructions.Quite impressed with Wicked Cushions, the build quality and fit is great.
