I bought the Custom Art Music One that I linked to in the above post. Most of the reviews I'd read agreed that it was an insanely good deal considering the quality-per-dollar ratio. And I don't regret it.

Maintenance: there's a little wire loop with a plastic handle included in the pelican case it ships with, lets you clean wax out of the canal. Tip: if you think one of your headphones is dead, just clean the wax out of the canal, it was blocking the sound. That's it – super simple, no idea what other maintenance you might be talking about.

Insertion/removal: nope, still quite easy. You have to give them a slight twist but definitely not hard.

Can't speak to the Music Two vs. Music One because I only have the latter, but I'll tell you that I've owned a decent number of headphones (in ear, over ear) and that the Music One are the best I've ever had.

EDIT: I swear I'm not shilling for this company. There are plenty of other great IEMs on the market. I just like these.

Thanks a lot for the feedback!
