Whether they are worth keeping or not will depend upon your own means and priorities. Of course, you are on a site filled with people for whom having only three headphones would seem like a cruel punishment. If you can tell the difference between them soundwise, appreciate that difference, and can afford to keep a harem, I say keep them. If you can't keep all three, I would keep the MrSpeakers. In fact, if I could only have one of the headphones that I have ever owned, heard, or heard of, it would be the AEON C's. For me, they are exactly neutral and excel in every aspect. Now, I don't want to come off like I am exaggerating. There are headphones that do specific things better or that have a different flavor that I like as much, but these are by far the best all-rounder, everyday headphone and by far the most comfortable. Because of their exceptional isolation, they also have a very high Wife Acceptance Factor. (In fact, my wife will often bring the AEON C to me and demand that I listen to them instead of whatever open headphones I'm listening to.) Of course, that is only my opinion. However, the numerous, seemingly endless accolades that these have received back up that opinion. Anyway, welcome aboard!
