Thanks, Tom. With Amazon Prime, the free returns means if it is too tight, I can swap for the larger. My IEM are in their own case, though having everything in one case might be nice. I flew cross country (including blistering red eye) this week with Mojo. With the length of the flights, normal delays and a not-so-normal delay, it helped the long hours pass nicely. I had some nice playlists ready in "off line content" and timed it just right. Mojo has provoked some interesting conversations, too!
