The OP stated he was going to use them with Apple devices via the lightning to 1/4" adapter which will probably struggle to deliver satisfying dynamics with either high impedance cans or planars. Open back cans have already gotten the 'thumbs down' from the family so if it comes down to a choice between soundstage and your family, I assume you'll choose family. So, closed cans it is, unless you want to go down the IEM route. That might be a solution if high isolation in both directions is needed, in which case i'd say investigate Etymotics.
