It's been some time I've posted in this thread, ever since I moved to another pair of IEM's, the experience had all been up and down. For those who are still deciding to get the MylarOne series, here's some advice from an ex-MylarOne user for all of you out there.
To start it off, let me describe my music tastes. My music collection varies from classic oldies of the Carpenters to modern mainstream music. Besides that, I'm a big fan of trance, house and euro-dance music from various DJ's (PvD, Tiesto & "Uncle Ben" to name a few). Obviously, a good amount of bass is what I look from the earphones that I wear.
The first IEM that got plugged into my ears are MylarOne's. Initial impression from me was the lack of bass (or some of you called it 'musical bass'). I was kinda disappointed with it at first but I'd remembered that I got it to accompany me during my bus travels, which worked kinda okay since it DID manage to block out some noise but I end up not hearing any good levels of bass at all due to the lower-level frequencies did manage to travel through my bones are not blocked.
It served me for more than a couple of months and finally I sold it off to another member here a couple months ago..

Now that I've got myself an EP630, I kinda missed the detailed mids that my MylarOne used to have. The Creative is actually quite bassy and had plenty of low-end power which is why I went for at the first place, but it turned out that the mids are all laid back when compared to to the Mylar. Despite that, I do felt that its sound-stage is actually wider than the Mylar and I'm kinda used to its sound signature already since I've been using it for some time. Isolation-wise, I had yet to test it on bus trips since I've just graduated and currently have yet to had the need to be on public transport..

But.. initial testing does prove that EP630 does isolate a little bit better than MylarOne's..

In the mean time, I've found out that I'm using more of my older EP480 earbuds than the EP630 IEM's when I'm out listening to music because I don't need total noise isolation while I'm at work. At home, I'm using my cheapo Philips HP250 can more than any other types of earphones at all, probably due to it's comfort and more than decent sounding quality that had sufficient clarity and bass.
As a conclusion, for those who thinks that they want to get these IEM's for noisy trips, don't expect much of the 'full-spectrum' of sound from IEM's since most of the time they do not provide 100% sound isolation to let you enjoy every single musical note. What it'll do is to seal off some noise so you wouldn't turn up the volume and end up having painful ears at the end of your musical session. Just don't expect hi-fi sound quality from it though (I did over estimate it.. what? it's my first IEM anyway..

)
Oh yeah, on a side note, newer iPod earbuds sucked.. Clarity and bass-wise, the one that is supplied with my 'fatty' Nano lost to my EP480 earbuds when compared side by side.
