Yes, by adding a male plug to the speaker's wiring (which is what I did years ago with the Q series) you can switch back and forth. I eventually got tired of inserting/removing the canalphones and simply added some backing to the speaker's mounting so they were placed closer to my ears which made them usable at any speed at very low volumes and with foam ear plugs when on longer trips. YMMV
