I think there is just as much air, but the slightly more U-shaped sound signature may mask some of that on certain tracks. For me, the green Andro's have a perfect balance of air and a fairly flat signature. I would see if you could demo the Solaris first if you like the sound of a BA design like I do. My Lyra II's seemed to be somewhere in the middle between the gold and green with the signature, but the imaging and sound-stage was very different being a single dynamic design. One more comment on the gold's, they have the best low frequency response control I have ever heard in an IEM or even a headphone.
