Can I ask you which model you did buy? I am in the process of doing precisely the same and wondering if their acrylic models are isolating enough. Silicon apparently isolates better but requires more maintenance, makes them more difficult to insert and remove, and I'm not fully convinced I should go for a Music Two sound-wise. Thanks a bunch!
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.
