3D scanning is a real step forwards.
Miles knows what he is doing. I was pleased to find him at the Guitar Show, and took the opportunity to have my ears scanned. The new plugs were delivered two weeks later, which is faster than anyone has delivered them in the past. 3D scanning is a real step forwards. My new ear plugs feel a much better fit than the plugs and IEMs I’ve had made in the past using rubberised gunk moulds.
