I agree. I had a NIB David Clark 10-40 that I bought 20 some yrs, ago.Never had them out of the box. I had another 10 40 that I used for those yrs then got a set of Bose. I could'nt get use to the light clamping pressure so I found the Headset Inc. kit and put it in both Clarks, started using the NIB pair and put the Bose back in the box. I prefer the Headset Inc. reduction.
