    Headphones which are swappable between open-back and closed-back

    I've recently come across a few headphones that are swappable between open-back and closed-back. For instance, HiFiMan's Edition S and Monoprice's Monolith M560. I was wondering how many of these are out there. Are there any that are on par with regular audiophile grade headphones?
