Man7rah, I believe I found your email and sent you a reply.
More higher end plug makers are starting to realize it is a good idea to put more plug options out there for the headphone arena.
The hope is they will eventually figure out that 4-pin XLRs are good plugs to think about releasing as well. But certainly other
connector makers have to be taking notice of those few that have been releasing headphone related plugs lately, so hopefully this will stimulate some new options from other places in the future as well (including 4-pin XLR connectors).
