Yes, I've learned that there is a difference between headphones with foam type cushions vs. those with the gel-type cushions (and an NRR rating), such as the Dave Clark products. The sound of a door closing is a good indicator. I always come back to using my Dave Clark 10S-DC stereo headset, with NRR 23dB, because I operate in a very noisy part of the house and find that it offers the best isolation over a wide frequency range. I hear a lot of complaints about Dave Clark being uncomfortable to wear, some based on experience many years ago, but find the 10S-DC to be just fine myself - perhaps the cushion design has improved over time?
