I think this is a very individual issue, because shape of head for comfort feel and our ears are not equal tuned when listen..
Our age matters as well, and I guess some of us at SZ are close to the hearing aid equipment age.

Tried many head phones during the years, at the moment I've found pleasure by use Shure SRH840 for the T4.
Also a low cost, light weight Sony set does a nice job connected to MicroArr.
