My rig is IEC60318-4 coupler. Sadly a person that sent my those forgot to include spare tips, so I had to measure them classic 711 way, so without pinna even tho they are shallow fit. Although Space Travel tips fit just fine, they do not have additional rubber that covers nozzle exit, so they may affect the sound.
I will measure ANC as soon as I get the tips and can fit it on pinna with seal.
Looks shouty
