Yes, I also did that test as well! They are so sleek that glasses, sun glasses, and just about any other piece of head gear you can think of, will fit with them on and be comfortable as they usually would be.
They really are low profile and I haven't had a single problem with them.
I even managed to put them on under a ski hat, helmet, goggles, and turtle neck while I was shredding down the slopes of Colorado on a snowboard while listening to my music on my Titan at the time.
I love this little device and will support it whole-heartedly. It's really worth the money.
