I recently purchased a pair of these HY80's to replace my original ear cushions on my Minelab headphones on my Excalibur II. I have read that some people glued them on with Aqua Seal or Gorilla Glue. I peeled the cushions off the plastic backing and repressed them on to the original headphone backings without any issues. They seem to fit well and be just a tad smaller then the original ear pads. Has anyone else switched them out using the procedure I used? Gluing the plastic back of the HY80's to the backing of the original headphones seemed a little messy and may prevent putting the original pads back on.
