Just a bit of a heads up really, anyone looking to replace the foam ear cups on their Howard Leight ear defenders with the gel variety. I bought some replacement ear cups of the gel type off the 'Bay', which arrived today. They seem a lot thicker than the originals and took all of 5 minutes to fit, being a straight replacement. They do feel a lot more comfortable and cost £8.44 including postage. They took around 3 weeks to arrive (from China) and to be honest, I am hard pushed to see any difference between these and others costing up to some £36.00. As to their longevity..........................we shall see, but at their price and being just a straight swap, they seem splendid value for money.
